What to do if Fronius TransPocket 4000 CEL Welding System shows Err | PE error?
- RRobert SantiagoAug 21, 2025
If you see the error message 'Err | PE' on your Fronius Welding System, it indicates that the earth-fault current watchdog has triggered the power source’s safety cut-out. To resolve this, switch off the power source, wait for 10 seconds, and then switch it on again. If the error persists after several attempts, you should contact After Sales Service.
