Measuring welding circuit resistance r
General 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
The calculated welding circuit resistance is displayed on the right-hand digital display.

NOTE!
Make sure that the contact between the earthing clamp and the workpiece is on a
cleaned section of the workpiece.
Make a grounding (earthing) connection to the workpiece
Open the TIG setup menu - level 2, or the rod electrode setup menu - level 2

NOTE!
Make sure that the contact between the electrode and the workpiece is on a cleaned
section of the workpiece.
While the measurement is being performed, the cooling unit and the cold wirefeeder are
deactivated.
Place the electrode fully on the surface of the workpiece
Briefly press the torch trigger or the Gas-test button
The welding circuit resistance is now calculated; during the measurement the right-
hand digital display reads "run".
The measurement is finished when the welding circuit resistance is shown on the
right-hand digital display (e.g. 11.4 milliohms)
