Kemppi X3 400-500A


X3 Powerful Tool for Serious Welders

Made In Finland

X3 MIG Welder is a trustworthy partner for a serious welder. It is a hard-boiled inverter-based MIG/MAG welding machine
by the Finnish manufacturer of quality welding equipment, Kemppi – the number one pioneer in energy efficient welding inverter technology in the world.

X3 MIG Welder is a welding system consisting of a power source that is available in two power options: 400 and 500 A, a wire feeder for 300 mm wire spools, and Kemppi’s GX welding gun with a Euro connection. Different cable lengths and wheel sets are available as an option. The machine connects to any 380-440-volt 3-phase mains supply. It can be used for gas-cooled MIG/MAG welding, and It accepts a wide range of filler wire diameters from 0.8 to 1.6 mm, and with cored wires up to 2.0 mm. The power source also supports carbon arc gouging* in both 400 and 500 amperage models.

The MIG/MAG process has been carefully tuned at Kemppi welding lab to give the welding arc an outstanding stability. This makes the arc easy to manage and minimizes the amount of spatter. The arc stability and weld quality are easily achieved also with inexpensive CO2 shielding gas. With less spatter, the time needed for post-weld grinding is reduced, and the welders can focus entirely on productive welding.
