The welding torch is a device that provides an arc for welding, cutting or related
processes using the relevant resources. A plasma-welding torch works with two
independently adjustable welding arcs (pilot and main arc). Both arcs are fed
from their own current source. The welding arcs are described as main and pilot
arc. The pilot arc is struck between a cooled cathodic tungsten electrode and a
liquid-cooled anodic copper nozzle. It is ignited with the aid of high-frequency
voltage and its main purpose is to promote ignition of the main welding arc. The
main arc is struck between the tungsten electrode and the anodic work piece.
The plasma gas emerges from the plasma nozzle aperture as a high-energy plas-
ma beam and provides the heat energy required for welding.
The additional material is added to the process in the form of rod or wire. It is
transported into the melt pool zone by means of a cold wire feeder or manually.
The arc and the molten pool are protected by inert gas or active gas. The gas
nozzle fixed at the front end of the torch feeds the protective gas around the arc
and over the molten pool. The cable assembly serves as a supply line and is fit-
ted with all necessary connection elements.
Fitting the torch body
1. Insert the tungsten electrode with the blunt end
approx. 5 mm into the torch cap.
2. Screw the torch cap into the torch body from the top as
far as it will go.
3. Loosen the torch cap again by one full anti-clockwise
rotation.
