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.
