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 inductiv-
ity 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
arranged may help to improve the welding
results. 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 resist-
ance 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
L/R alignment Calibration of welding circuit inductivity and resistance can be done both in TIG setup
2nd and rod electrode setup 2nd.
NOTE!
L/R alignment must be carried out separately for each welding process.
