GTAW (TIG) WELDING

 

 

 

 

 

 

The POWER FEED® / Power Wave system is excellent

 

 

for Touch Start TIG welding.

 

 

 

 

 

 

The system supports TIG torches with or without gas

 

 

control valves. TIG torches with gas control valves con-

 

 

nect directly to the gas flow regulator. For TIG torches

 

 

without gas control valves, connect the output gas

 

 

hose on the wire feeder to the TIG torch gas hose.

 

 

The wire feeder gas solenoid may be enabled or dis-

 

 

abled by parameter P.8 in the set-up menu found in this

 

 

operations section.
