The AC / DC welding device is used for joint and build-up welding. In addition to steel, nickel, titanium, zirconium and copper, weldable materials are also aluminum alloys. With the plasma taphole process, it is possible to weld in one layer without processing edges, material thicknesses of up to 12mm.


An arc, which burns between a non-melting tungsten electrode, around which plasma gas flows, and the workpiece, is geometrically constricted by a copper nozzle. A plasma arc (beam) is created, which has a significantly higher energy density than a comparable free-burning arc. Thanks to the concentrated arc, in conjunction with the controllable plasma gas, high welding speeds and welding depths can be achieved with narrow heat-affected zones, which saves time and money. The high welding speed means that only a narrow heat-affected zone is formed, which results in less thermal distortion in the component.
