Error messages (power source)

7.2 Error messages (power source)
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.
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.
