DO NOT operate a water-cooled torch unless water is flowing. Water doesn’t flow until the solenoid is actu- ated.

If using a water-cooled torch with a Magnum water cooler, connect the cooler water outlet to the “Water Valve In” fitting. Connect the TIG torch inlet to the “Water Valve Out” fitting.

If using a water-cooled torch with a free-running water supply, install a water line between the welder “Water Inlet” and the supply. Include a strainer in the water supply line to prevent dirt particles from obstructing water flow in the valve and cooling chamber of the TIG torch. Failure to do so could result in water valve mal- function and overheating of the water-cooled torch. Connect the torch water line to the welder “Water Out” fitting. Use a nonmetallic drain line from the electrode connection to the drain or water recirculating pump.

For other water coolers or torches, consult the manu- facturer’s instructions for the water cooler or TIG torch being used.

STICK ELECTRODE CABLE

CONNECTION

Turn the Power switch Off. Run the electrode and work cables through the strain relief holes below the welding output terminals and connect the cables to the proper terminals. This strain relief prevents dam- age to the welding output terminals if the cables are pulled excessively. Select cable size according to Table A.3

WARNING

Do not connect a TIG torch and stick electrode cable at the same time. They will both be electrically HOT whenever the output terminals are energized.
