For additional safety information, it is strongly recommended that you purchase a copy of “Safety in Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society, P.O. Box 351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199. BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS. FOR ENGINE powered equipment. 1.h. To avoid scalding, do not remove the radiator pressure cap when the engine is hot. 1.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running. ____________________________________________________ 1.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors. ____________________________________________________ 1.c. Do not add the fuel near an open flame welding arc or when the engine is running. Stop the engine and allow it to cool before refueling to prevent spilled fuel from vaporizing on contact with hot engine parts and igniting. Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been eliminated. ____________________________________________________ 1.d. Keep all equipment safety guards, covers and devices in position and in good repair.Keep hands, hair, clothing and tools away from V-belts, gears, fans and all other moving parts when starting, operating or repairing equipment. ____________________________________________________ 1.e. In some cases it may be necessary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is complete. Always use the greatest care when working near moving parts. ___________________________________________________ 1.f. Do not put your hands near the engine fan. Do not attempt to override the governor or idler by pushing on the throttle control rods while the engine is running. ELECTRIC AND MAGNETIC FIELDS may be dangerous 2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines 2.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding. 2.c. Exposure to EMF fields in welding may have other health effects which are now not known. 2.d. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit: 2.d.1. Route the electrode and work cables together - Secure them with tape when possible. 2.d.2. Never coil the electrode lead around your body. 2.d.3. Do not place your body between the electrode and work cables. If the electrode cable is on your right side, the work cable should also be on your right side. 2.d.4. Connect the work cable to the workpiece as close as possible to the area being welded. ___________________________________________________ 1.g. To prevent accidentally starting gasoline engines while turning the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate. 2.d.5. Do not work next to welding power source. Mar ‘95 Return to Master TOC Return to Master TOC ii ELECTRIC SHOCK can kill. ARC RAYS can burn. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. 4.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards. 3.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground. 4.b. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays. In addition to the normal safety precautions, if welding must be performed under electrically hazardous conditions (in damp locations or while wearing wet clothing; on metal structures such as floors, gratings or scaffolds; when in cramped positions such as sitting, kneeling or lying, if there is a high risk of unavoidable or accidental contact with the workpiece or ground) use the following equipment: • Semiautomatic DC Constant Voltage (Wire) Welder. • DC Manual (Stick) Welder. • AC Welder with Reduced Voltage Control. 4.c. Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal. 3.c. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or semiautomatic welding gun are also electrically “hot”. 3.d. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded. 3.e. Ground the work or metal to be welded to a good electrical (earth) ground. 3.f. Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation. Return to Master TOC ii SAFETY 3.g. Never dip the electrode in water for cooling. 3.h. Never simultaneously touch electrically “hot” parts of electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders. 3.i. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock. 3.j. Also see Items 6.c. and 8. FUMES AND GASES can be dangerous. 5.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases.When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone. When welding with electrodes which require special ventilation such as stainless or hard facing (see instructions on container or MSDS) or on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low as possible and below Threshold Limit Values (TLV) using local exhaust or mechanical ventilation. In confined spaces or in some circumstances, outdoors, a respirator may be required. Additional precautions are also required when welding on galvanized steel. 5. b. The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV limits. 5.c. Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and other irritating products. 5.d. Shielding gases used for arc welding can displace air and cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe. Return to Master TOC 5.e. Read and understand the manufacturer’s instructions for this equipment and the consumables to be used, including the material safety data sheet (MSDS) and follow your employer’s safety practices. MSDS forms are available from your welding distributor or from the manufacturer. 5.f. Also see item 1.b. AUG ‘06 Return to Master TOC iii WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available. 6.b. Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations. Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1) and the operating information for the equipment being used. Return to Master TOC 6.c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard. 6.d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even though they have been “cleaned”. For information, purchase “Recommended Safe Practices for the Preparation for Welding and Cutting of Containers and Piping That Have Held Hazardous Substances”, AWS F4.1 from the American Welding Society (see address above). 6.e. Vent hollow castings or containers before heating, cutting or welding. They may explode. 6.f. Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position or in confined places. Always wear safety glasses with side shields when in a welding area. Return to Master TOC iii SAFETY 6.g. Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail. 6.h. Also see item 1.c. CYLINDER may explode if damaged. 7.a. Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition. 7.b. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support. 7.c. Cylinders should be located: • Away from areas where they may be struck or subjected to physical damage. • A safe distance from arc welding or cutting operations and any other source of heat, sparks, or flame. 7.d. Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder. 7.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve. 7.f. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use. 7.g. Read and follow the instructions on compressed gas cylinders, associated equipment, and CGA publication P-l, “Precautions for Safe Handling of Compressed Gases in Cylinders,” available from the Compressed Gas Association 1235 Jefferson Davis Highway, Arlington, VA 22202. FOR ELECTRICALLY powered equipment. 8.a. Turn off input power using the disconnect switch at the fuse box before working on the equipment. 8.b. Install equipment in accordance with the U.S. National Electrical Code, all local codes and the manufacturer’s recommendations. 8.c. Ground the equipment in accordance with the U.S. National Electrical Code and the manufacturer’s recommendations. Return to Master TOC Mar ‘95 Return to Master TOC Return to Master TOC Return to Master TOC Return to Master TOC iv iv SAFETY PRÉCAUTIONS DE SÛRETÉ Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent dans ce manuel aussi bien que les précautions de sûreté générales suivantes: Sûreté Pour Soudage A L’Arc 1. Protegez-vous contre la secousse électrique: a. Les circuits à l’électrode et à la piéce sont sous tension quand la machine à souder est en marche. Eviter toujours tout contact entre les parties sous tension et la peau nue ou les vétements mouillés. Porter des gants secs et sans trous pour isoler les mains. b. Faire trés attention de bien s’isoler de la masse quand on soude dans des endroits humides, ou sur un plancher metallique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grande partie du corps peut être en contact avec la masse. c. Maintenir le porte-électrode, la pince de masse, le câble de soudage et la machine à souder en bon et sûr état defonctionnement. d.Ne jamais plonger le porte-électrode dans l’eau pour le refroidir. e. Ne jamais toucher simultanément les parties sous tension des porte-électrodes connectés à deux machines à souder parce que la tension entre les deux pinces peut être le total de la tension à vide des deux machines. f. Si on utilise la machine à souder comme une source de courant pour soudage semi-automatique, ces precautions pour le porte-électrode s’applicuent aussi au pistolet de soudage. 2. Dans le cas de travail au dessus du niveau du sol, se protéger contre les chutes dans le cas ou on recoit un choc. Ne jamais enrouler le câble-électrode autour de n’importe quelle partie du corps. 3. Un coup d’arc peut être plus sévère qu’un coup de soliel, donc: zones où l’on pique le laitier. 6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque d’incendie dû aux étincelles. 7. Quand on ne soude pas, poser la pince à une endroit isolé de la masse. Un court-circuit accidental peut provoquer un échauffement et un risque d’incendie. 8. S’assurer que la masse est connectée le plus prés possible de la zone de travail qu’il est pratique de le faire. Si on place la masse sur la charpente de la construction ou d’autres endroits éloignés de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer des risques d’incendie ou d’echauffement des chaines et des câbles jusqu’à ce qu’ils se rompent. 9. Assurer une ventilation suffisante dans la zone de soudage. Ceci est particuliérement important pour le soudage de tôles galvanisées plombées, ou cadmiées ou tout autre métal qui produit des fumeés toxiques. 10. Ne pas souder en présence de vapeurs de chlore provenant d’opérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs du solvant pour produire du phosgéne (gas fortement toxique) ou autres produits irritants. 11. Pour obtenir de plus amples renseignements sur la sûreté, voir le code “Code for safety in welding and cutting” CSA Standard W 117.2-1974. PRÉCAUTIONS DE SÛRETÉ POUR LES MACHINES À SOUDER À TRANSFORMATEUR ET À REDRESSEUR a. Utiliser un bon masque avec un verre filtrant approprié ainsi qu’un verre blanc afin de se protéger les yeux du rayonnement de l’arc et des projections quand on soude ou quand on regarde l’arc. b. Porter des vêtements convenables afin de protéger la peau de soudeur et des aides contre le rayonnement de l‘arc. c. Protéger l’autre personnel travaillant à proximité au soudage à l’aide d’écrans appropriés et non-inflammables. 1. Relier à la terre le chassis du poste conformement au code de l’électricité et aux recommendations du fabricant. Le dispositif de montage ou la piece à souder doit être branché à une bonne mise à la terre. 4. Des gouttes de laitier en fusion sont émises de l’arc de soudage. Se protéger avec des vêtements de protection libres de l’huile, tels que les gants en cuir, chemise épaisse, pantalons sans revers, et chaussures montantes. 3. Avant de faires des travaux à l’interieur de poste, la debrancher à l’interrupteur à la boite de fusibles. 2. Autant que possible, I’installation et l’entretien du poste seront effectués par un électricien qualifié. 4. Garder tous les couvercles et dispositifs de sûreté à leur place. 5. Toujours porter des lunettes de sécurité dans la zone de soudage. Utiliser des lunettes avec écrans lateraux dans les Mar. ‘93 v - MASTER TABLE OF CONTENTS FOR ALL SECTIONS RETURN TO MAIN MENU Page Safety .................................................................................................................................................i-iv Installation.............................................................................................................................Section A Operation...............................................................................................................................Section B Accessories ..........................................................................................................................Section C Maintenance ..........................................................................................................................Section D Theory of Operation .............................................................................................................Section E Troubleshooting and Repair ................................................................................................Section F Electrical Diagrams ..............................................................................................................Section G Parts Manuals .................................................................................P438 (455M) & P450 (455M/STT) POWER WAVE 455M/MSTT v Return to Master TOC Section A TABLE OF CONTENTS - INSTALLATION SECTION - Installation.............................................................................................................................Section A Technical Specifications.......................................................................................................A-2, A-3 Safety Precautions ......................................................................................................................A-4 Select Suitable Location..............................................................................................................A-4 Lifting ....................................................................................................................................A-4 Stacking ................................................................................................................................A-4 Machine Grounding.....................................................................................................................A-4 High Frequency Protection..........................................................................................................A-4 Input Connection .........................................................................................................................A-5 Return to Master TOC Input Fuse and Supply Wire Considerations ........................................................................A-5 Input Voltage Change Over (For Multiple Input Voltage Machines Only).............................A-6 Welding with Multiple Power Waves ...........................................................................................A-6 Electrode and Work Cable Connections .....................................................................................A-7 Negative Electrode Polarity.........................................................................................................A-7 Voltage Sensing ..........................................................................................................................A-8 Work Voltage Sensing ..........................................................................................................A-9 Electrode Voltage Sensing ...................................................................................................A-9 Power Wave / Power Feed Wire Feeder Interconnections.........................................................A-9 Control Cable Specifications ................................................................................................A-9 External I/O Connector .........................................................................................................A-9 Return to Master TOC Return to Master TOC Dip Switch Settings and Locations .....................................................................................A-10 Control Board Dip Switch ...................................................................................................A-10 Feed Head Board Dip Switch .............................................................................................A-10 Devicenet/Gateway Board Dip Switch, Bank (S2)..............................................................A-11 POWER WAVE 455M/MSTT Section A Return to Master TOC Return to Section TOC A-2 A-2 INSTALLATION TECHNICAL SPECIFICATIONS - POWER WAVE 455M (K2202-1, K2202-3) INPUT AT RATED OUTPUT - THREE PHASE ONLY AMPS / VOLTS / DUTY CYCLE INPUT CURRENT AMPS 208/230/460/575V - 60HZ.

WARNING ELECTRIC SHOCK can kill. DO NOT MOUNT OVER COMBUSTIBLE SURFACES. Where there is a combustible surface directly under stationary or fixed electrical equipment, that surface shall be covered with a steel plate at least .06”(1.6mm) thick, which shall extend not less than 5.90”(150mm) beyond the equipment on all sides. Return to Master TOC Return to Section TOC • Only qualified personnel should perform this installation. • Turn the input power OFF at the disconnect switch or fuse box before working on this equipment. Turn off the input power to any other equipment connected to the welding system at the disconnect switch or fuse box before working on the equipment. LIFTING • Do not touch electrically hot parts. STACKING • Always connect the Power Wave grounding lug (located inside the reconnect input access door) to a proper safety (Earth) ground. Power Wave machines can be stacked a maximum of three high. CAUTION SELECT SUITABLE LOCATION Return to Master TOC Return to Master TOC Return to Section TOC Do not use Power Waves in outdoor environments. The Power Wave power source should not be subjected to falling water, nor should any parts of it be submerged in water. Doing so may cause improper operation as well as pose a safety hazard. The best practice is to keep the machine in a dry, sheltered area. Return to Section TOC Lift the machine by the lift bail only. The lift bail is designed to lift the power source only. Do not attempt to lift the Power Wave with accessories attached to it. Place the welder where clean cooling air can freely circulate in through the rear louvers and out through the case sides and bottom. Dirt, dust, or any foreign material that can be drawn into the welder should be kept at a minimum. Do not use air filters on the air intake, because the air flow will be restricted. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdowns. Machines above code 10500 are equipped with F.A.N. (fan as needed) circuitry. The fan runs whenever the output is enabled, whether under loaded or open circuit conditions. The fan also runs for a period of time (approximately 5 minutes) after the output is disabled, to ensure all components are properly cooled. If desired, the F.A.N. feature can be disabled (causing the fan to run whenever the power source is on). To disable F.A.N., connect leads 444 and X3A together at the output of the solid state fan control relay, located on the back of the Control PC board enclosure. (See the Wiring Diagram.) The bottom machine must always be placed on a firm, secure, level surface. There is a danger of machines toppling over if this precaution is not taken. MACHINE GROUNDING The frame of the welder must be grounded. A ground terminal marked with the symbol is located inside the reconnect/input access door for this purpose. See your local and national electrical codes for proper grounding methods. HIGH FREQUENCY PROTECTION Locate the Power Wave away from radio controlled machinery. CAUTION The normal operation of the Power Wave may adversely affect the operation of RF controlled equipment, which may result in bodily injury or damage to the equipment.

A 1.75 inch (45 mm) diameter access hole for the input supply is located on the upper left case back next to the input access door. Connect L1, L2, L3 and ground according to the Input Supply Connection Diagram decal located on the inside of the input access door, or refer to Figure A.1. Refer to the Technical Specifications at the beginning of this Installation section for recommended fuse and wire sizes. Fuse the input circuit with the recommended super lag fuse or delay type breakers (also called “inverse time” or “thermal/magnetic” circuit breakers). Choose an input and grounding wire size according to local or national electrical codes. Using fuses or circuit breakers smaller than recommended may result in “nuisance” shut-offs from welder inrush currents, even if the machine is not being used at high currents. POWER WAVE 455M/MSTT Return to Master TOC Return to Master TOC Return to Section TOC Return to Section TOC A-6 A-6 INSTALLATION INPUT VOLTAGE CHANGE OVER (FOR MULTIPLE INPUT VOLTAGE MACHINES ONLY) WELDING WITH MULTIPLE POWER WAVES CAUTION Welders are shipped connected for the highest input voltage listed on the rating plate. To move this connection to a different input voltage, see the diagram located on the inside of the input access door. (Figure A.1.) If the main reconnect switch or link position is placed in the wrong position, the welder will not produce output power. Special care must be taken when more than one Power Wave is welding simultaneously on a single part. Arc blow and arc interference may occur or be magnified. If the Auxiliary (A) lead is placed in the wrong position, there are two possible results. If the lead is placed in a position higher than the applied line voltage, the welder may not come on at all. If the auxiliary (A) lead is placed in a position lower than the applied line voltage, the welder will not come on, and the two circuit breakers in the reconnect area will open. If this occurs, turn off the input voltage, properly connect the (A) lead, reset the breakers, and try again. Each power source requires a work lead from the work terminal to the welding fixture. Do not combine all of the work leads into one lead. The welding travel directions should be in the direction moving away from the work lead as shown in Figure A.2. Connect all of the work sense leads from each power source to the work piece at the end of the weld. For the best results when pulse welding, set the wire size and wire feed speed the same for all the Power Waves.

Every welding gun requires a separate shielding gas regulator for proper flow rate and shielding gas coverage. Do not attempt to supply shielding gas for two or more guns from only one regulator. If an anti-spatter system is in use, each gun must have its own anti-spatter system. See Figure A.2. Return to Master TOC Return to Section TOC ELECTRODE AND WORK CABLE CONNECTIONS Connect a work lead of sufficient size and length (per Table A.1) between the proper output terminal on the power source and the work. Be sure the connection to the work makes tight metal-to-metal electrical contact. To avoid interference problems with other equipment and to achieve the best possible operation, route all cables directly to the work or wire feeder. Avoid excessive lengths and do not coil excess cable. Do not tightly bundle the electrode and work cables together. Use K1796 coaxial welding cables wherever possible. Return to Master TOC Return to Section TOC Minimum work and electrode cables sizes are as follows: TABLE A.1 (Current (60% Duty Cycle) MINIMUM COPPER WORK CABLE SIZE AWG Up To 100 Ft. Length (30 m) 400 Amps 500 Amps 600 Amps 2/0 (67 mm ) 3/0 (85 mm2) 3/0 (85 mm2) Return to Master TOC Most welding applications run with the electrode being positive (+). For those applications, connect one end of the electrode cable to the positive (+) output terminal on the power source (located beneath the spring loaded output cover near the bottom of the case front). Connect the other end of the electrode cable to the wire drive feed plate using the stud, lockwasher, and nut provided on the wire drive feed plate. The electrode cable lug must be against the feed plate. Be sure the connection to the feed plate makes tight metal-to-metal electrical contact. The electrode cable should be sized according to the specifications given in Table A.1. Connect a work lead from the negative (-) power source output terminal to the work piece. The work piece connection must be firm and secure, especially if pulse welding is planned. CAUTION Excessive voltage drops caused by poor work piece connections often result in unsatisfactory welding performance. When welding with the STT process, use the positive output connection labeled (STT) for STT welding. (If desired, other welding modes can be used on this terminal; however, their average output current will be limited to 325 amps.) For non-STT processes, use the positive output connection labeled (Power Wave), so that the full output range of the machine is available. CAUTION 2 When using an inverter type power source like the Power Wave, use the largest welding (electrode and ground) cables that are practical. At least 2/0 copper wire - even if the average output current would not normally require it. CAUTION Return to Section TOC A-7 INSTALLATION When pulsing, the pulse current can reach very high levels. Voltage drops can become excessive, leading to poor welding characteristics, if undersized welding cables are used. Do not connect the STT and Power Wave terminals together. Paralleling the terminals will bypass STT circuitry and severely deteriorate STT welding performance. NEGATIVE ELECTRODE POLARITY When negative electrode polarity is required, such as in some Innershield applications, reverse the output connections at the power source (electrode cable to the negative (-) terminal, and work cable to the positive (+) terminal). When operating with electrode polarity negative, the Dip switch 7 must be set to ON on the Wire Feed Head PC Board. The default setting of the switch is OFF to represent positive electrode polarity. To set the Negative Polarity switch on Wire Feed Head PC board, refer to the section DIP SWITCH SETTINGS AND LOCATIONS. POWER WAVE 455M/MSTT Return to Master TOC Return to Section TOC A-8 The sense leads connect to the Power Wave at the four-pin connector located underneath the output terminal cover. Lead 67 senses electrode voltage. Lead 21 senses work voltage. VOLTAGE SENSING The best arc performance occurs when the Power Wave has accurate data about the arc conditions. Depending upon the process, inductance within the electrode and work lead cables can influence the voltage apparent at the terminals of the welder. Voltage sense leads improve the accuracy of the arc conditions and can have a dramatic effect on performance. Enable the voltage sense leads as follows: TABLE A.2 CAUTION Return to Master TOC If the voltage sensing is enabled but the sense leads are missing or improperly connected, extremely high welding outputs may occur.

It is recommended that genuine Lincoln control cables be used at all times. Lincoln cables are specifically designed for the communication and power needs of the Power Wave / Power Feed system. For processes requiring work voltage sensing, connect the (21) work voltage sense lead from the Power Wave to the work. Attach the sense lead to the work as close to the weld as practical. To enable the work voltage sensing in the Power Wave, refer to the section DIP SWITCH SETTINGS AND LOCATIONS. Enabling or disabling electrode voltage sensing is automatically configured through software. Electrode sense lead 67 must be connected at the wire feeder. CAUTION The use of non-standard cables, especially in lengths greater than 25 feet, can lead to communication problems (system shutdowns), poor motor acceleration (poor arc starting) and low wire driving force (wire feeding problems).

Depending on configuration, it can support constant current, constant voltage, Surface Tension Transfer and pulse welding modes. • Designed to the IEC 974-1 Standard. The Power Wave power source is designed to be used with the family of Power Feed wire feeders, operating as a system. Each component in the system has special circuitry to “talk with” the other system components, so each component (power source, wire feeder, electrical accessories) knows what the other is doing at all times. The components communicate using ArcLink protocol. Robotic systems can communicate with other industrial machines via DeviceNET protocol. The result is a highly intigrated and flexible welding cell. The Power Wave 455/R is a high performance, digitally controlled inverter welding power source capable of complex, high-speed waveform control. Properly equipped, it can support the GMAW, GMAW-P, FCAW, GTAW and STT processes. It carries an output rating of either 450 amps, 38 volts; or 400 amps, 36 volts (both at 100% duty cycle), depending on input voltage and frequency. The Surface Tension transfer process (STT) is supported at currents up to 325 amps, at 100% duty cycle. • Power Wave 455 multiple process output ranges: 5 - 570 amps • Easy access for input connections. Connections are simple strip and clamp (no lugs required). • F.A.N. (Fan As Needed). Cooling fan runs only when necessary (above Code 10500 only, and all STT machines). • Modular construction for easy servicing. • Thermostatically protected. • Electronic over-current protection. • Input over-voltage protection. • Utilizes digital signal processing and microprocessor control. • Simple, reliable input voltage change over. • All system components communicate and transfer information. • Auto device recognition simplifies accessory cable connections. If the duty cycle is exceeded, a thermostat will shut off the output until the machine cools to a reasonable operating temperature.

Each machine is factory preprogrammed with multiple welding procedures, typically including GMAW, GMAW-P, FCAW, GTAW and STT for a variety of materials, including mild steel, stainless steel, cored wires, and aluminum. The STT process supports mild steel and stainless steel welding. • Control Cables (for use on FANUC robot arm, 22 pin to 14 pin, 10 ft), K1804-1 The Power Wave 455/R is recommended only for automatic or mechanized applications such as robotic welding. LIMITATIONS RECOMMENDED EQUIPMENT • Power Waves are not to be used in outdoor environments. Automatic Operation All welding programs and procedures are set through software for the robotic Power Wave. FANUC robots equipped with RJ-3 controllers may communicate directly with the Power Wave. Other pieces of equipment such as PLCs or computers can communicate with the Power Wave using DeviceNET. All wire welding processes require a robotic Power Feed wire feeder. • Control Cables (for use on FANUC robot arm, 22 pin to 14 pin, 18 in), K1805-1 • Control Cables (for use on FANUC robot arm, 22 pin to 14 pin, 18 in), K1804-2 • The Power Wave 455/R is not suitable for SMAW, CAC-A or other processes not listed. • Only ArcLink Power Feed wire feeders and user interfaces may be used. Other Lincoln wire feeders or non-Lincoln wire feeders cannot be used. DUTY CYCLE AND TIME PERIOD The Power Feed wire feeders are capable of welding at a 100% duty cycle (continuous welding). The power source will be the limiting factor in determining system duty cycle capability. Note that the duty cycle is based upon a ten minute period. A 60% duty cycle represents 6 minutes of welding and 4 minutes of idling in a ten minute period. POWER WAVE 455M/MSTT Return to Master TOC Return to Section TOC B-6 CASE FRONT CONTROLS 3.

The preprogrammed voltage is the best average voltage for a given wire feed speed. With synergic programs, when the wire feed speed changes, the Power Wave will automatically adjust the corresponding voltage. Wave control adjusts the inductance of the wave shape. (This adjustment is often referred to as "pinch". Inductance is inversely proportional to pinch.) Increasing wave control greater than 0 results in a harsher, colder arc, while decreasing the wave control to less than 0 provides a softer, hotter arc. (See Figure B.2.) FIGURE B.2 – CV WAVE CONTROL CHARACTERISTICS Wave Control +10.0 Wave Control 0.00 Wave Control -10.0 Current Return to Master TOC Time Return to Section TOC B-7 POWER WAVE 455M/MSTT Return to Master TOC Return to Master TOC Return to Section TOC Return to Section TOC B-8 OPERATION PULSE WELDING Pulse welding procedures are set by controlling an overall “arc length” variable. When pulse welding, the arc voltage is highly dependent upon the waveform. The peak current, background current, rise time, fall time and pulse frequency all affect the voltage. The exact voltage for a given wire feed speed can only be predicted when all the pulsing waveform parameters are known. Using a preset voltage becomes impractical, and instead the arc length is set by adjusting “trim.” The Power Wave utilizes “adaptive control” to compensate for changes in electrical stick-out while welding. (Electrical stick-out is the distance from the contact tip to the work piece.) The Power Wave waveforms are optimized for a 0.75" (19mm) stick-out. The adaptive behavior supports a range of stickouts from 0.50" (13mm) to 1.25" (32mm). At very low or high wire feed speeds, the adaptive range may be less due to reaching the physical limitations of the welding process. Trim adjusts the arc length and ranges from 0.50 to 1.50, with a nominal value of 1.00. Trim values greater than 1.00 increase the arc length, while values less than 1.00 decrease the arc length. Wave control in pulse programs usually adjusts the focus or shape of the arc. Wave control values greater than 0 increase the pulse frequency while decreasing the background current, resulting in a tight, stiff arc best for high speed sheet metal welding. Wave control values less than 0 decrease the pulse frequency while increasing the background current for a soft arc good for out-of-position welding. (See Figure B.3.) Most pulse welding programs are synergic. As the wire feed speed is adjusted, the Power Wave will automatically recalculate the waveform parameters to maintain similar arc properties.

They are not drawn to scale, and are intended only for the purpose of showing how the variables affect the waveform. Trim in the STT mode adjusts the tailout and background portion of the waveform. Trim values greater than 1.0 add more energy to the weld and make the weld puddle hotter; trim values less than 1.0 reduce energy to weld. A nominal value of 1.0 will work for most applications. (See Figure B.4.) Return to Master TOC Return to Master TOC Return to Section TOC Return to Section TOC FIGURE B.4 – STT TRIM CONTROL CHARACTERISTICS Trim 1.50 Current Trim 1.00 Time Trim 0.50 For most programs, peak current is adjusted by wave control values. A value of +10.0 maximizes the peak current, while a wave control of -10.0 minimizes peak current. In general, the peak current is proportional to torch arc length. (See Figure B.5.) NOTE: The ranges on Wave Control and Trim are dependent on the weld programs. The values shown are typical ranges.

The water cooler is designed to cool only one welding gun and should be not used to cool multiple guns or other devices. FIELD INSTALLED • Return to Section TOC ACCESSORIES Gas Guard Regulator (K659-1) The Gas Guard regulator is available as an optional accessory for the Power Feed Robotic wire drive unit. Install the 5/8-18 male outlet on the regulator to the proper 5/8-18 female gas inlet on the back panel of the wire drive. Secure the fitting with the flow adjuster key at the top. • Voltage Sense Leads (K940-10, -25 or -50) The voltage sense leads connect at the front of the machine. (See Figure A.2.) • Power Wave Water Cooler (K1767-1)* The K1767-1 is the recommended water cooler for the Power Wave. Incorporated into the cooler is an automatic flow sensor to detect low coolant flow. In the event of a low flow condition, a fault signal is sent to the Power Wave, and welding output automatically stops to protect the torch. Water cooler manufacturers often specify additives to the coolant such as fungicides or alkalies. Follow the manufacturers’ recommendations to achieve proper operation and long lifetime without clogging. • Water Flow Sensor (K1536-1) Water cooled guns can be damaged very quickly if they are used even momentarily without water flowing. Recommend practice is to install a water flow sensor such as on the water return line of the torch. When fully integrated into the welding system, the sensor will prevent welding if no water flow is present. • Dual Cylinder Undercarriage, K1570-1* • Coaxial Welding Cable, K1796 *The Dual Cylinder Undercarriage, K1570-1, is not compatible in combination with the Power Wave Water Cooler K1767-1.

GENERAL DESCRIPTION The Power Wave 455M/MSTT power source is designed to be a part of a modular, multi-process welding system. It is a high performance, digitally controlled inverter welding power source capable of complex, high-speed waveform control. Depending upon configuration, it can support constant current, constant voltage, surface tension transfer and pulse welding modes. Each machine is factory preprogrammed with multiple welding procedures. Typically these procedures include GMAW, GMAW-P, FCAW, GTAW and LEFT S.B. CAP. V/F RIGHT S.B. CAP.

The STT process supports mild steel and stainless steel welding. PW455M/STT only. The Power Wave 455M/STT has an output rating of either 450 amps at 38 volts or 400 amps at 36 volts. The two output ratings are dependent upon input voltage and frequency. Both have a duty cycle of 100%. The STT process is rated at currents up to 325 amps at a 100% duty cycle.

Refer to Figure E.2. The initial input power is applied to the Power Wave 455M through a line switch located on the front of the machine. Two phases of the three-phase input power are applied to the Input Board and both auxiliary transformers. The various secondary voltages developed by transformer T1 are applied to the Input Board, the fan motor (via a control relay) and the Bus Board rectifier. The 65VDC produced from the Bus Board rectifier is used by the Bus Board to provide various DC voltages for the Power Board, the Feed Head Board and the wire feeder receptacle. The 115/230VAC developed on the secondary of auxiliary transformer T2 is applied to the 115VAC receptacle and to the water cooler receptacle. the precharge or "soft start" sequence, these two phases are current limited by the Input Board. The AC input voltage is rectified, and the resultant DC voltage is applied through the reconnect switches to the input capacitors located on the right and left switch boards. The Control Board monitors the voltage across the capacitors. When the capacitors have charged to an acceptable level, the Control Board signals the Input Board to energize the main input contactor, making all three phases of input power, without current limiting, available to the input capacitors. At this point the Power Wave 455M is in the "Run Mode" of operation. If the capacitors become undervoltaged, overvoltaged, or unbalanced, the Control Board will signal the Input Board to de-energize the main input contactor, and the Power Wave 455M will be disabled. See Figure E.2. The two phases that are connected to the Input Board, through the input line switch SW1, are connected to the input rectifier through the CR1 precharge relay.

Each contains an input capacitor and insulated gate bipolar transistor (IGBT) switching circuitry. Refer to Figure E.3. When the machine reconnect switches are configured for a lower input voltage (below 300VAC), the input capacitors are connected in parallel. When the machine is configured for higher input voltages (300VAC and above), the input capacitors are connected in series. When the input capacitors are fully charged, they act as power supplies for the IGBT switching circuits. The insulated gate bipolar transistors switch the DC power from the input capacitors "on and off," thus supplying pulsed DC current to the main transformer primary windings. See IGBT OPERATION DISCUSSION AND DIAGRAMS in this section. Each switch board feeds current to a separate, oppositely wound primary winding in the Main Transformer. The reverse directions of current flow through the main transformer primaries, and the offset timing of the IGBT switch boards induce an AC square wave output signal at the secondary of the main transformer. Current transformers located on the switch boards monitor the primary currents. If the primary currents become abnormally high, the Control Board will shut off the IGBTs, thus disabling the machine’s output. The firing of the two switch boards occurs during halves of a 50microsecond interval, creating a constant 20 KHZ output. NOTE: Unshaded areas of Block Logic Diagram are the subject of discussion.

This regulated 40VDC is applied to the Feed Head Board, the Power Board, and the wire feeder receptacle. The switching power supplies on the Power Board supply a variety of regulated DC voltages to the Control Board and a +20VDC to the STT Chopper Board.

Externally the Power Wave 455R communicates using the industry standard Device Net protocols. The Gateway Board makes the translation between the two platforms possible. The Power Wave 455R does not have a dedicated interface device or board. The robot (or other input device – PLC, etc.) acts as the user interface, issuing commands through the Device Net protocol that are translated by the Gateway Board to ArcLink compatible messages.

The function generator and weld files exist within the Control Board hardware and software. Digital command signals and feedback information is received and processed at the Control Board. Software within the Control Board processes the command and feedback information and sends the appropriate pulse width modulation (PWM) signals (see PULSE WIDTH MODULATION in this section) to the switch board IGBTs. In this manner, the digitally controlled high-speed welding waveform is created. The Control Board also monitors and controls the STT (Surface Tension Transfer) circuitry incorporated in the Power Wave 455R. STT output currents and arc voltages are monitored, and the appropriated gate firing signals are applied (or removed) from the STT Chopper Board and switch boards to create a low spatter, low fume MIG welding process. See GENERAL DESCRIPTION OF STT (SURFACE TENSION TRANSFER PROCESS) in this section. In addition, the Control Board monitors the thermostats, the main transformer primary currents and input filter capacitor voltages. Depending on the fault condition, the Control Board will activate the thermal and/or the status light and will disable or reduce the machine output. In some conditions the input contactor will be de-energized.

Since the outuput choke is in series with the negative leg of hte output rectifier and also in series with the welding load, a filtered DC output is applied to the machine output terminals. Refer to Figure E.7. When in the STT mode, the control circuit monitors the voltage conditions at the arc, and turns the STT chopper module on or of as necessary to generate an STT output waveform. The STT current transducer in the STT circuit signals the control board to limit output to 375 amps maximum. POWER WAVE 455M/MSTT Return to Master TOC Return to Master TOC Return to Master TOC Return to Master TOC Return to Section TOC Return to Section TOC Return to Section TOC Return to Section TOC E-9 THEORY OF OPERATION E-9 THERMAL PROTECTION OVER CURRENT PROTECTION Three normally closed (NC) thermostats protect the machine from excessive operating temperatures. These thermostats are wired in series and are connected to the control board. One of the thermostats is located on the heat sink of the output rectifier, one on the DC bus, and one on the output choke. Excessive temperatures may be caused by a lack of cooling air or by operating the machine beyond its duty cycle or output rating. If excessive operating temperatures should occur, the thermostats will prevent output from the machine. The yellow thermal light, located on the front of the machine, will be illuminated. The thermostats are self-resetting once the machine cools sufficiently. If the thermostat shutdown was caused by excessive output or duty cycle and the fan is operating normally, the power switch may be left on and the reset should occur within a 15-minute period. If the fan is not turning or the intake air louvers are obstructed, the power must be removed from the machine and the fan condition or air obstruction corrected. On later production machines (above code 10500) the cooling fan runs only when necessary. The F.A.N. (fan as needed) system is controlled by the Control Board via a solid state relay. If the average current exceeds 570 amps, the peak current will be limited to 100 amps until the average current decreases to under 50 amps or the system is retriggered. PROTECTIVE CIRCUITS 3. Voltage across a capacitor is under 70 volts. (This would be due to improper input voltage connections.) Protective circuits are designed into the Power Wave 455/R to sense trouble and shut down the machine before damage occurs to the machine’s internal components. UNDER/OVER VOLTAGE PROTECTION A protective circuit is included on the Control Board to monitor the voltage across the input capacitors. In the event that a capacitor voltage is too high, too low, or becomes unbalanced side-to-side, the protection circuit will de-energize the input contactor. Machine output will be disabled, and the "soft start" mode will be repeated. The protection circuit will prevent output if any of the following circumstances occur. 1. Capacitor conditioning is required. (This may be required if the machine has been off for a long period of time and is connected for high input voltage operation.) 2. Voltage across a capacitor exceeds 390 volts. (This could result from high line surges or improper input voltage connections.) 4. Internal component damage.

ACTIVE A. PASSIVE INSULATED GATE BIPOLAR TRANSISTOR (IGBT) OPERATION An IGBT is a type of transistor. IGBTs are semiconductors well suited for high frequency switching and high current applications. Drawing A shows an IGBT in a passive mode. There is no gate signal, zero volts relative to the source, and therefore, no current flow. The drain terminal of the IGBT may be connected to a voltage supply; but since there is no conduction, the circuit will not supply current to components connected to the source. The circuit is turned off like a light switch in the OFF position. Drawing B shows the IGBT in an active mode. When the gate signal, a positive DC voltage relative to the source, is applied to the gate terminal of the IGBT, it is capable of conducting current. A voltage supply connected to the drain terminal will allow the IGBT to conduct and supply current to circuit components coupled to the source. Current will flow through the conducting IGBT to downstream components as long as the positive gate signal is present. This is similar to turning ON a light switch.

Changing the pulse width is known as MODULATION. Pulse Width Modulation is the varying of the pulse width over the allowed range of a cycle to affect the output of the machine. MAXIMUM OUTPUT MINIMUM OUTPUT Return to Master TOC By controlling the duration of the gate signal, the IGBT is turned on and off for different durations during a cycle. The top drawing below shows the minimum output signal possible over a 50-microsecond time period. Return to Section TOC The shaded portion of the signal represents one IGBT group1, conducting for 1 microsecond. The negative portion is the other IGBT group. The dwell time (off time) is 48 microseconds (both IGBT groups off). Since only 2 microseconds of the 50-microsecond time period are devoted to conducting, the output power is minimized. 1 By holding the gate signals on for 24 microseconds each and allowing only 2 microseconds of dwell or off time (one microsecond during each half cycle) during the 50 microsecond cycle, the output is maximized. The darkened area under the minimum output curve can be compared to the area under the maximum output curve. The more darkened area, the more power is present. An IGBT group consists of the sets of IGBT modules grouped onto one switch board.

Have an electrician install and service this equipment. Turn the machine OFF before working on equipment. Do not touch electrically hot parts. Sometimes machine failures appear to be due to PC board failures. These problems can sometimes be traced to poor electrical connections. To avoid problems when troubleshooting and replacing PC boards, please use the following procedure: 1. Determine to the best of your technical ability that the PC board is the most likely component causing the failure symptom. 2. Check for loose connections at the PC board to assure that the PC board is properly connected. Return to Master TOC Return to Master TOC Return to Section TOC 3. If the problem persists, replace the suspect PC board using standard practices to avoid static electrical damage and electrical shock. Read the warning inside the static resistant bag and perform the following procedures: Return to Section TOC F-3 PC Board can be damaged by static electricity. ATTENTION Static-Sensitive Devices Handle only at Static-Safe Workstations • Remove your body’s static charge before opening the static-shielding bag. Wear an anti-static wrist strap. For safety, use a 1 Meg ohm resistive cord connected to a grounded part of the equipment frame. • If you don’t have a wrist strap, touch an unpainted, grounded, part of the equipment frame. Keep touching the frame to prevent static build-up. Be sure not to touch any electrically live parts at the same time. • Remove the PC Board from the static-shielding bag and place it directly into the equipment. Don’t set the PC Board on or near paper, plastic or cloth which could have a static charge. If the PC Board can’t be installed immediately, put it back in the staticshielding bag. • If the PC Board uses protective shorting jumpers, don’t remove them until installation is complete. • If you return a PC Board to The Lincoln Electric Company for credit, it must be in the static-shielding bag. This will prevent further damage and allow proper failure analysis. 4. Test the machine to determine if the failure symptom has been corrected by the replacement PC board. NOTE: Allow the machine to heat up so that all electrical components can reach their operating temperature. 5. Remove the replacement PC board and substitute it with the original PC board to recreate the original problem. a. If the original problem does not reappear by substituting the original board, then the PC board was not the problem. Continue to look for bad connections in the control wiring harness, junction blocks, and terminal strips. b. If the original problem is recreated by substitution of the original board, then PC board was the problem. Reinstall replacement PC board and test machine. the the the the 6. Always indicate that this procedure was followed when warranty reports are to be submitted. NOTE: Following this procedure and writing on the warranty report, “INSTALLED AND SWITCHED PC BOARDS TO VERIFY PROBLEM,” will help avoid denial of legitimate PC board warranty claims. • Tools which come in contact with the PC Board must be either conductive, anti-static or static-dissipative.
