electrode is overloaded. This means that there is a risk of an excessively large cap
being formed.
Causes:
- The tungsten electrode does not have a large enough diameter
- Main current I has been set to too high a value
1
- "Balance" has been set too far towards "+"
Remedies:
- Use a tungsten electrode with a bigger diameter
- Reduce the main current
Important! The "Electrode overload" indicator (41) is fine-tuned to work with the
following tungsten electrodes:
- TIG-AC welding: Pure tungsten electrodes
- TIG-DC welding: Ceriated electrodes
For all other electrodes, the "Electrode overload" indicator (41) must be taken as a
guideline only
