WARNING! Work that is carried out incorrectly can cause serious injury and
damage. The following activities must only be carried out by trained and quali-
fied personnel. Follow the safety regulations.
Adjusting the
PTW 500 tungs-
ten electrode
*) Loosen the torch cap - caution, the tungsten
electrode may fall out of the plasma torch if the
torch is in a particular position.
Alongside the specified plasma gas flow rate, the position of the tungsten electrode
plays a crucial role in determining the loading limits.
By loading limits we mean the maximum possible welding current
- for a particular plasma nozzle,
- for a particular plasma gas flow rate,
- for a particular tungsten electrode position.
The setting process for the tungsten electrode for plasma welding / plasma brazing is
described in the following section.
