The plasma welding torches work with two independently adjustable arcs (pilot
and main arcs) that are supplied with power from the power source. The pilot
arc burns between a cathodically poled tungsten electrode and an anodically
poled copper nozzle. It is ignited by means of a high-frequency voltage and
used to ignite the main arc. The main arc burns between the tungsten electrode
and the anodically poled workpiece. The plasma gas is expelled from the
plasma nozzle's opening as a high-energy plasma jet and provides the thermal
energy required for welding. The filler material can be optionally fed to the
process in wire form. The arc and the molten pool are protected by the inert
gas or the active gas components. The cable assembly serves as a supply line
and is equipped with all connection elements.
