square wave ac/dc tig welder can used to welded aluminum,aluminum alloy,magnesium alloy,carbon steel,stainless steel
1.upgrade square wave power source,current with high speed through the zero ,arc is stable no high frequency stabilizer is necessary.
2.good arc stiffness,heat concentrated,easy to fill wire .is especially suitable for filler wire welding in bicycle inductry.
3.super oxide film clean capability ,clean time is adjustable steplessly ,beautiful and bright welded seam.
4.has connector to foot control,convenient for worker's operation.
5.built in over current ,overy heat ,overy voltage ,low voltage alarm and protection circuit ,safe and relaible when operating.
6.high duty cycle,may worl continuously with high current.
7.suitable for welding aluminum and its alloy ,carbon steel,stainless steel,copper ,titanium etc metal
