If an increased welding circuit resistance is detected, e.g. after changing the welding torch,
this may mean that the following components are faulty:
- Torch hosepack
- Welding torch
- Grounding (earthing) connection to the workpiece
- Grounding cable
Welding circuit inductivity L [μH]
The way that the hosepack is arranged has
a very significant effect on the weld proper-
ties.
Particularly with pulsed-arc welding and AC
welding, a high welding circuit inductivity
may occur, depending on the length of the
hosepack and on the way that it is arran-
ged. The result is that the current rise is re-
stricted.
The weld results can be optimised by chan-
ging the arrangement of the torch hose-
pack.
The hosepack must be laid out as shown in
the illustration.
