Gas tungsten arc welding (GTAW), also known as tungsten inert gas ( TIG welder) welding, is an arc welding process that uses a nonconsumable tunsten electrode to produce the weld.
DC/AC TIG welding machine, mosfet technology, high frequency arc starting. AC suitable for welding aluminum alloy products. DC for welding stainless steel ,alloy steel,carton steel,copper and other non-ferrous metals. Support MMA welding
Argon arc welding, advanced MOSFET technology, Stepless current adjustment, smooth arc and stable welding performance, gas saving.
