Measuring the
welding circuit re-
sistance "r"
IMPORTANT! For optimum welding results, determine the welding circuit resistance " r "
before starting welding.
The welding circuit resistance " r " must also be determined if one of the following compo-
nents of the welding system is changed:
- Torch hosepack
- Welding torch
- Grounding cable
For more information on determining the welding circuit resistance, refer to the 2nd TIG
menu (see page70).
