Installation
Power Cord Plug Connection (Figure 2.2)
1. Be sure to connect the power cord plug to the appropriate power voltage, and use a proper
hookup to avoid damage to internal circuitry. Typically, the ground wire is GREEN with a
YELLOW stripe.
2. Ensure that the power cord is properly connected to the power switch to prevent oxidation.
Make sure the power voltage is within the specified safety range.
3. Please refer to the Plug Wiring Instructions of this manual for detailed instructions on plug
wiring.
Connecting the Cables to the Machine (Figure 2.4)
1. Properly connect the high pressure tube of pressed air to copper connector.
2. Ensure that copper screw at the opposite end of the torch is securely connected to the torch.
To avoid gas leakage, turn screw clockwise until it locks into position. Connect the mobile plug
at one end of the grounding cable pincer to the positive terminal located on the front panel;
and then tighten.
3. Ensure that the air plug of the torch is connected to the switch connector on the panel. For
cutters with pilot arc, connect the fork connector to the red terminal on the front panel.
Check-list before Operation
1. Ensure that the cutting machine is properly grounded.
2. Ensure that all connectors are connected appropriately and firmly.
3. Ensure that power voltages are correct.
Operating the Plasma Cutter
1. Make sure the machine on/off switch is in the off position. Plug the power cord plug into the
outlet.
2. Connect air compressor with air regulator/filter.
3. Connect the ground clamp to your work piece. Caution: Rust or paint on the work piece could
create an open circuit; therefore, the contact point should be cleaned thoroughly to ensure a
good connection between clamp and work piece.
4. Turn on the power switch. The cooling fan should start to operate and the LED should come
on. The front panel should show the machine's electrical current volume, and you can adjust it
by turning the nob below the display.
