DC TIG OPERATION
⚠WARNING
High voltage danger from power source!
• Consult a qualified electrician for proper installation of receptacle at the power source. This welder
must be grounded while in use to protect the operator from electrical shock. If you are not sure if
your outlet is properly grounded, have it checked by a qualified electrician. Do not cut off the
grounding prong or alter the plug in any way and do not use any adapter, other than the supplied
adapter, between the welder's power cord and the power source receptacle. Make sure the POWER
switch is OFF then connect your welder's power cord to a properly grounded 230 VAC (220V -
240V), 60 HZ, single phase, 50-amp power source. If operating on 120V, attach the 120V Adapter
cord to the unit power cord and then connect the assembly to a properly grounded 120 VAC (110V-
130V), 60 Hz, single phase, 25-amp power source.
⚠WARNING
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN!
• Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc or begin
welding until you are adequately protected. Wear flame-proof welding gloves, a heavy long-sleeved
shirt, trousers without cuffs, high topped shoes, and an ANSI approved welding helmet.
⚠CAUTION
Be aware that the TIG torch will be electrically HOT when the Input Power Switch on the welder is turned
on.
1. Remove the ground cable and the electrode holder from the weld output connections. Install
the ground cable to the Positive (+) weld output connection (Figure 8 pg.22).
2. Secure the ground clamp to the work piece.
3. Connect a regulator to a bottle of ARGON gas. Then connect the gas connection from the TIG
torch to the regulator.
4. Connect the TIG torch weld cable to the Negative (-) weld output connection.
5. Connect Foot Pedal 5 pin to 5 Pin Trigger Assembly (Figure 8).
6. Set the desired amperage on the amperage control knob on the front panel of the welder.
7. Turn on the input power switch on the welder.
8. Turn on the regulator on the bottle of shielding gas and adjust the regulator to approximately
20 CFH. Open the shielding gas valve on the torch to start the flow of shielding gas.
9. To operate using Lift ARC, follow steps in DC TIG OPERATION on pages 49-50 in this manual.
9. Follow these steps for striking an arc while Lift Start TIG welding.
9.1 Open the shielding gas valve on the torch handle to begin gas flow.
9.2 Rest the TIG torch nozzle on the work piece, taking care to not touch the installed tungsten
electrode.
