Machine faults (error messages)

7.2 Machine faults (error messages)
A welding machine error is indicated by the collective fault signal lamp (A1) lighting up and an
error code (see table) being displayed in the machine control display. In the event of a machine
error, the power unit shuts down.
The display of possible error numbers depends on the machine version (interfaces/functions).
•
If multiple errors occur, these are displayed in succession.
•
Document machine errors and inform service staff as necessary.
