Single-phase welding units on wheels, microprocessor-controlled, suitable for MIG/MAG (continuous or pulsed), TIG-DC (continuous or pulsed) and electrode. A 3,3” display shows all the welding parameters, and makes the adjustment very easy and intuitive. Ideal for applications in welding carpentries and body workshops and specifically for the welding of stainless steel, aluminium and zinc-coated steels. Ideal for the use with five welding torches (not at the same time), two gas bottles (Ar/Co2 and Ar, Ø170mm max) and three wire spools (Fe/CrNi, Al and CuSi) enabling then a simple and fast use.
