Troubleshooting

EN
In the unlikely event of a fault, do not send the welder to us without speaking to us beforehand. A
short telephone call and a short description of the fault is usually enough to identify the cause of
the problem. In most cases problems can be resolved with a correct replacement part, which we will
send to you as quickly as possible.
This prevents unnecessary costs for all parties involved.
You can find our service contact details on the back of this operating manual.
