GTAW (TIG) WELDING

 

 

 

 

 

 

 

The POWER FEED™ / Power Wave system is excel-

 

 

 

lent for Touch Start TIG welding.

 

 

 

 

 

 

 

The system supports TIG torches with or without gas

 

 

 

control valves. TIG torches with gas control valves

 

 

 

connect 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.
