messages
A welding machine error is indicated by an error code being displayed (see table) on the display
on the machine control.
In the event of a machine error, the power unit is shut 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.
