Rectifying faults
All products are subject to rigorous production checks and final checks. If, despite this, something fails to
work at any time, please check the product using the following flowchart. If none of the fault rectification
procedures described leads to the correct functioning of the product, please inform your authorised
dealer.

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.
