Why Kemppi MASTERTIG AC/DC 2500 Welding System shows Uin Err error message?
- K
  kevin15Aug 8, 2025
  If the Kemppi Welding System power source won't start and shows a Uin Err error message with the over or under voltage signal lamp on, it could be due to a wrong supply voltage selection. Disconnect the power source plug and select the correct supply voltage using the selector switch S003 (ACDC 2500 and 2500W). Also, ensure all supply phases are present, as a missing phase could be the cause.

Why fans remain rotating but the panel isn't operating correctly on Kemppi MASTERTIG AC/DC 2500?
- M
  melissakelleySep 1, 2025
  If, after starting your Kemppi Welding System, the fans keep rotating but the panel isn't working correctly, it could be due to a bad contact in the flat cable between the function panel and control card A002. Check the flat cables and connectors X1 and X2. Alternatively, the panel itself might be faulty. If some panel function is not working after resetting the panel, replace the panel membrane or the panel.
