NOTE:
Lift TIG operation requires an optional valved TIG torch & argon gas cylinder.
NOTE:
The Weldforce 175MST is a DC (Direct Current) output welder only, this means that it is
unable
to
TIG weld reactive metals such as Aluminium alloys and Brass (which require AC output). DC TIG output is
suitable for steel, stainless steel and copper.
