Low Gas Indicator Light
This light will be on when the gas flow is low.
Ground Cable Connection
Connect the ground cable to the postive (+) receptacle on the front of the plasma
cutter. The ground cable clamp connects to your work piece.
Torch Control Cable Connection
The black cable on the torch connects to the 3-Prong receptacle on the front of
the machine. Push on to snap in place. This is the control cable for the torch.
Torch Arc Starting Cable Connection
This connector is for the red cable of the torch. It is used to help the arc starting.
Torch Connection
Connect the torch to the negative (-) receptacle.
Protection indicator Light
When the unit is in thermal overload, is over voltage or lacking voltage, the
indicator will be on and the machine will stop working. When the unit is cooled
down and voltage stabilizes, the unit will return to work automatically.
Power indicator Light
This light will turn on when the input power cord is plugged into the power supply
and the power switch on the back of the plasma cutter is in the "ON" position.
Gas Hose Connection
The gas hose connection is on the back panel of the plasma cutter. This
connections requires a 1/4 inch NPT connection (Not supplied). The other end of
the gas hose connects to an air compressor or compressed air supply.
Power switch
It is the on/off switch. After the machine is connected to the input power supply,
turn on this switch. The power indicator on the front panel will turn on.
Power cord
Specification Table

-Always be aware of your work environment. Be sure to keep other people,
especially children, away from you while you are cutting.
-Keep harmful arc rays shielded from the view of others.
-Mount the plasma cutter on a secure bench or cart that will keep the welder
secure and prevent it from tipping over or falling.
1.2 Your Plasma Cutter’s Condition
-Check all cables, power cord and torch to be sure the insulation is not damaged.
Always replace or repair damaged components before using the plasma cutter.
-Check all components to ensure they are clean and in good operating condition
before use.
1.3 Use of Your Plasma Cutter
Do not operate the plasma cutter if the torch is wet. Do not immerse the plasma
torch. Do not stand in water while using this plasma cutter. These components
and the plasma cutter must be completely dry before attempting to use it.
-Follow the instructions in this manual.
-Keep the plasma cutter in the off position when not in use.
-Connect ground lead as close to the area being cut as possible to ensure a
good ground.
-Do not allow any body part to come in contact with the material being cut, or to
the ground or electrode from another plasma cutter or welder.
-Do not cut if you are in an awkward position. Always have a secure stance while
cutting to prevent accidents. Wear a safety harness if working above ground.
-Do not drape cables over or around your body.
- Wear eye protection (see ANSI Z49.1 safety standard) while cutting to protect
your eyes from harmful UV and IR ray’s.
-Wear proper gloves and protective clothing to prevent your skin from being

-Do not overuse or overheat your plasma cutter. Allow proper cooling time
between duty cycles.
-Keep hands and fingers away from moving parts.
- Do not point the Plasma torch at any body part or at anyone else.
-Always use this plasma cutter in the rated duty cycle to prevent excessive heat
and failure.
1.4 Specific Areas of Danger,
Caution or Warning
Electrical Shock
Plasma cutters can produce a shock that can cause injury or death.
Touching electrically live parts can cause fatal shocks and severe
burns. While cutting, all metal components connected to the wire
are electrically hot. Poor ground connections are a hazard, so secure the ground
lead before cutting.
-Wear dry protective apparel: coat, shirt, gloves and insulated footwear.
