( 1 )Argon itself is insoluble in metal and does not respond with metal. It can successfully isolate air. In the welding procedure, the arc can additionally instantly eliminate the oxide film externally of the molten pool, can be utilized for welding easily oxidized, nitrided, chemically active non-ferrous steels such as stainless-steel and various alloys.

( 2) Tungsten arc is security combustion also in small welding current( much less than 10A), specifically appropriate for slim plate, ultra-thin alloy welding.

( 3 )The heat source and also filler cord can be controlled respectively, and also the warmth input and welding placement can be conveniently changed. It is likewise an optimal technique to realize single-side welding and double-side developing.

( 4) The filling up welding wire decreases do not pass through the arc, no dash and lovely weld creating.
