circuit inductivity
L
The way that the hosepack is arranged has a very significant effect on the weld properties.
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 arranged. The
result is that the current rise is restricted.
Correct arrangement of the hosepack
Changing the way the hosepack is arran-
ged may help to improve the welding re-
sults. The hosepack must be laid out as
shown in the illustration.

circuit resistance
R
Measuring the welding circuit resistance "r" provides information on the overall resistance
of the torch hosepack, welding torch, workpiece and grounding (earthing) cable.
If an increased welding circuit resistance is detected, e.g. after changing the torch, this may
mean that the following components are faulty:
-
Torch hosepack
-
Welding torch
-
Grounding (earthing) connection to the workpiece
-
Grounding (earthing) cable
