INSTALLATION
DO NOT operate a water-cooled torch unless water is
flowing. Water doesn’t flow until solenoid is actuated.
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
malfunction 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 conditions, consult the manufacturer’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
damage to the welding output terminals if the cables
are pulled excessively. Select cable size according to
Table 1.
Observe the safety precautions necessary for
handling and using compressed gas containers.
Contact your supplier for specific information.
___________________________________________
The welder fittings have the following threads: Gas
Inlet and Outlet: 5/8”-18 right-hand female; Water inlet
and Outlet: 5/8”-18 left-hand female. The cylinder of
inert shielding gas must be equipped with a pressure
regulator and flow meter. Install a hose between the
flow meter and gas inlet on the welder.
WARNING
Do not connect a TIG torch and stick electrode cable
at the same time. They will both be electrically HOT
whenever the output contactor is energized.
