7.2 Error messages (power source)
A welding machine error will be signalled by an error code (see table) on the control display. In
the event of an error, the power unit shuts down.
The display of possible error numbers depends on the machine version (interfaces/functions).
• Document machine errors and inform service staff as necessary.
• If multiple errors occur, these are displayed in succession.
