Warnings and Safety
Welding and plasma cutting may be dangerous to the operator and to bystanders, if the
equipment is not operated properly. Welding or cutting must be performed in accordance with
all relevant safety regulations. Carefully read and understand this instruction manual before
installing and operating this equipment.
Changing function modes during welding may damage
equipment.
Before welding, disconnect the electrode-holder cable from the
equipment.
A circuit breaker is required to prevent electrical overload of the
equipment.
Only high quality welding tools should be used.
Electric Shock can be fatal.
Ensure that ground cable is connected in accordance with
applicable safety codes.
Never touch electrodes, wires, or circuit components with bare
hands. Wear dry welding gloves when welding.
The operator must be insulated from the work piece.
Smoke and gas can be harmful to health.
Ensure that the working area is well ventilated.
Avoid breathing smoke and gas generated during the welding
process. Cutting and welding can cause cancer because of the
smoke that comes from the welds and cuts.
Arc-light emission can be harmful to eyes and skin.
Always wear a welding helmet, anti-radiation glass, and work
clothes while welding.
Ensure that people in or near the working area are protected.
Welding splash is a fire hazard.
Keep flammable material away from the work place.
Keep a fire extinguisher nearby, and have all personnel trained in
7
ForceCut 42i 110v/220v PFC 40amp Plasma Cutter
its use.
Surface noise generated while welding or cutting can be harmful
to hearing.
In the event of a machine fault.
Refer to this instruction manual.
If the fault cannot be determined, contact your local dealer or
supplier for assistance.

Safety Tips
Consider the following tips to ensure safe operation of your welding/cutting equipment:

Ensure that this welding equipment is installed in an area free of corrosive chemical gases,
flammable gases or materials, and explosive chemicals.

The area should contain little dust, and have a humidity of no more than 80%.

Operate the welding equipment in an area sheltered from direct sunlight and precipitation. Work
area temperature should be maintained at to

If, because of an overload, the machine suddenly stops, and it is necessary to restart it, leave the
internal fan operating to lower the inside temperature.

Always wear protective clothing and a welding mask to protect your skin.

Wear safety goggles designed to darken the arc generated by your machine.

Wear suitable noise protection to protect your hearing.

Ensure that machine is grounded through the power cord or on the machine case.

Never operate the machine in bare feet or on a wet floor.

Never switch the machine off while it’s in use. Doing so will damage the internal circuitry.

Ensure that your circuit breaker is rated to handle the current requirements of your machine.

Use a UL approved receptacles and plugs with your machine. Never hard wire the machine to
main power.

Work in a well-ventilated area to avoid smoke. Keep your head out of the smoke. Ensure that air is
flowing away from you to avoid inhaling smoke.

Ensure proper ventilation through the machine’s louvers. Maintain a distance of at least 12
inches between this cutting equipment and any other objects in the work area.

Use a screen or curtain designed to keep passer byes from viewing the arc.

The arc spray and metal spray from machine use may cause nearby fires. Use caution.

If, after reviewing this manual, you have any problems in setting up or operating your machine,
contact us at [email protected].

Installation
Unpacking
1. Inspect each item for possible shipping damage. If damage is evident, contact your distributor and / or shipping
company before proceeding with the installation.
Input Power Connections
Note: Check your power source for correct voltage before plugging in or connecting the unit
Gas Connections
A. Connecting Gas Supply to Unit
Connect the gas line to the inlet port of the gas filter on the rear panel.
B. Check Air Quality
To test the quality of air, put the RUN / SET switch in the SET (down) position, check if there are Any oil or moisture
in the air.

Layout Of The Front And Rear Panel
1.
Power Light: The light will illuminate when the unit is powered on
2.
Temperature /Over-Heat Light: When the duty cycle is reach, the TEMP will turn on. Once it is safe to operate
the machine, the light will turn off. If duty cycle is reached, allow machine to run with the fan on to accelerate
cooling.
3.
Tip/Air Light
When adequate air pressure is reached, the Tip/Air light should turn on
4.
Pilot/Voltage Light: The Pilot/Voltage light is illuminated when the machine is ready to use.
5.
Amperage Control Knob: Allows the user to precisely set the desired amperage output. The machine is
limited to 30A when connected to 110v power supply
6.
RUN/SET: When cutting the, turn the switch to “RUN”; when doing a gas test, turn to the “SET”.

ForceCut 42i 110v/220v PFC 40amp Plasma Cutter
Basic Operation
1. Ensure that all cables are connected to the machine.
2. Ensure that the machine’s OFF/ON switch is set to OFF, and plug the machine into the electrical
outlet.
3. Connect the air compressor supply line to the air input side on the unit.
4. Turn the ON/OFF switch to ON. The cooling fans should operate and the ON indicator LED or power
switch (if applicable) should illuminate.
5. Clean the contact point on the work piece to ensure a good electrical connection. Ensure that no rust
of paint is present that could create an open circuit.
6. Connect the ground clamp to the work piece to be cut.
7. Connect the torch to the unit properly.
8. With the pilot arc knob connected, you should get a full continuous arc when the trigger on the torch
is pressed.
9. Depress the button on your torch to start the arc and begin cutting.
10. You can test the air to insure that is it properly flowing by selecting Gas (Air) Test. Air will pass
through the torch.
11. If necessary remove slag from the under part of the cut using a grinder or chisel.
13
ForceCut 42i 110v/220v PFC 40amp Plasma Cutter
Cutting Methods
Different material thicknesses require different cutting techniques.

Thin material: Start perpendicular to the work piece. It is unnecessary to angle or start on the
edge, as the arc will pass through quickly.
 Medium material: Angle the torch tip to avoid damaging the tip. Once the arc passes through the
material, you may begin cutting normally.
 Thick material: Drill a pilot hole through which to start your arc, or start on the edge of the work
piece.
Never cut material on a flat surface. Raise the work piece above the surface to avoid blow back which
may burn you or cause fires.
Real Time Arc-Curve Delay
When cutting thick materials you must maintain a steady even motion in the direction of the cut. Moving
the torch too quickly causes an arc-curve delay. An arc-curve delay can leave the work piece with uncut
sections, requiring you to re-cut those sections, which could distort or damage the work piece.
To avoid arc-curve delay, allow the arc to pass completely through the work piece before moving too far
ahead. The arc-curve should lag not more than the thickness of the material being cut. In other words, if
the work piece is one-half inch thick, the arc curve should lag not more than one-half inch behind the
torch, as shown below.

Routine Maintenance
The life of your machine and the quality of the work performed using your machine, will be
enhanced by practicing periodic routine maintenance.
• At regular intervals, clear dust that may accumulate in the machine using clean and dry
compressed air. If the working condition has heavy smoke and pollution, the welding machine
should be cleaned once a month.
• Keep the machine exterior clean with mild soap and water.
• Do not walk on or store items on the cables or cords.
• Do not jar, drop, or stack items on top of the machine.
• Always connect the machine to a well-grounded electrical outlet.
• Always check the torch consumables before and after use and ensure that they are clear of
obstructions, and that no parts are damaged.
• Replace any worn or damaged consumables before using machine.
• For periods of prolonged non-use, remove cables and store them in their original boxes in a
cool dry place.
