The RESANTA SAI-250AD AC/DC welding machine is a modern inverter argon-arc unit that allows you to work both on direct current (welding of ferrous and stainless steels, copper, titanium, etc.) and on alternating current (alloys of aluminum, magnesium, copper alloys of large thickness etc.), where it is required to remove oxides from the welded surface in the TIG mode, and MMA welding with a coated electrode (rutile and basic coating) is also possible.
