GTAW (TIG) WELDING
The Power Feed / PowerWave system is excellent for Touch Start TIG welding.
The system supports both 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 Power Feed™ 10M Single Wire Feeder.
