AC DC TIG-MMA PLUSE Welding Machine WSME400/ TIG Welding/ TIG Welder/ ARC Welding/ ARC Welder/ Welding/ Welder

WSME series are AC/ DC tig welder for Aluminum, copper and magnesium and their alloys are best welded using alternating current ( AC) . AC TIG should be utilized when welding aluminum due to its unique properties. Aluminum, when exposed to welding, forms an oxide layer on the surface ( commonly called sapphire) , which can contaminate the weld.

PULSE current is also most useful when welding dissimilar metals ( e.g. welding steel to aluminum) . In case of dissimilar metals, the joint must have an accurate fit, with proper gap dimensions and bevel angles. Care should be taken to avoid melting excessive base material. PULSE current is particularly useful for these applications, as it helps limit the heat input.
