• • • • • • user exits the MEMORY mode by using the SELECT switch. pinch settings are preferable for welding FCAW and GMAW with CO2. Most self-shielded wires work well at an Arc Control setting of 5. In the Pulse Mode, the Arc control regulates the frequency of the pulse. In the Pulse & Pulse Mode, the Arc Control regulates the frequency of oscillations between high and low level of amperage. In the CC-Stick modes, the Arc Control regulates the Arc Force to adjust the short circuit current. The minimum setting will produce a soft arc and will result in minimal spatter. The maximum setting will produce a crisp arc and will minimize electrode sticking. The Arc-control adjustment will be selected by toggling the SELECT switch until the LED next to ARC CONTROL is lit. The Arc-control value will be displayed. Arc-control can be adjusted by positioning the SET switch up or down. The default value is "OFF." The value is adjustable from –10.0 to 10.0 in 0.1 increments. If the SET switch is pushed up, the four dashes will change to "S-1" to indicate that the present weld mode and associated parameters will be Saved to user memory #1 when the SELECT switch is used to exit the memory mode. Pressing the SET switch down past the four dashes will cause the display to change to "r-1" to indicate that the weld mode and associated parameters currently stored in user memory #1 will be recalled when the SELECT switch is used to exit the memory mode. The following table summarizes the action taken when the user exits the memory mode: MSP3 Action taken when the user uses the SELECT switch to exit the MEMORY mode display "S-8" Save to user memory #8 … … "S-2" Save to user memory #2 "S-1" Save to user memory #1 "---" Exit "r-1" Recall from user memory #1 "r-2" Recall from user memory #2 … … "r-8" Recall from user memory #8 Crater • The Crater function offers the ability to set an endpoint for WFS and Voltage that will be reached over a specified time period. At the end of the weld when the trigger is released, the crater timer will begin and the WFS and Volts settings will ramp down from the Weld Mode WFS and Voltage settings to the Crater WFS and Voltage settings over the time selected. This creates a ramp down of the WFS and Volts during the Crater time. • The Crater timer will be selected by toggling the SELECT switch until the LED next to CRATER is lit and flashing. A crater time may be adjusted using the SET switch. • The default value is "OFF" (0 seconds). • Crater time is adjustable from 0 to 10.0 seconds in 0.1 second increments. • In the GMAW, FCAW, and Power weld modes, crater WFS and voltage are adjustable using the control knobs on the upper case front. This in indicated by the flashing LED’s next to "WFS" and "VOLTS.". • In the GMAW-P weld modes, Crater WFS and trim are adjustable. This is indicated by the flashing LEDs next to "WFS" and "TRIM.". When a memory save or memory recall is performed, the MSP3 panel will briefly scroll a text message to indicate that an action occurred. When a memory saved is performed, "SavEd" will be displayed. When a memory recall is performed, "rEcALLEd" will be displayed. When the memory mode is exited when the four dashes are displayed, the display stays on "r-1" or "s-1" to show the memory position. If the user attempts to restore from memory location that was not previously saved, the memory mode will exit without scrolling the "rEcALLEd" message as an indication that no action occurred. There will be no timeout time associated with memory saving and recalling. The user must exit the memory mode using the SELECT switch. Pulse & Pulse Welding Mode On this machine, Lincoln has introduced the possibility to weld with "Pulse-on-Pulse" MIG process for aluminium. Burnback • The Burnback feature will allow current to continue to flow for a specified time period at the end of a weld after wire feeding has stopped. • The Burnback timer will be selected by toggling the SELECT switch until the LED next to BURNBACK is lit. A burnback time may be adjusted using the SET switch. • The default value is "OFF" (0 seconds). • Burnback time is adjustable from 0 to 0.25 seconds in 0.01 second increments. Pulse-on-Pulse uses a modification of the Pulsed MIG process where the output is quickly switched between a Low-Energy Pulse procedure and a High-Energy Pulse procedure. Memory - Functional Specification The memory mode is entered when the MEMORY LED is illuminated and exited when the MEMORY LED is extinguished using the SELECT switch. Each time the MEMORY LED is selected using the SELECT switch, the display on the MSP3 will show four dashes "----" to indicate that no action will occur if the A-6
