Why Kemppi MASTERTIG AC/DC 2500W Welding System shows Uin Err error message?
- C
  Cheryl SparksAug 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.

  Rachel ShawAug 21, 2025
  If the Kemppi Welding System power source doesn't start and the panel lights and displays remain blank, the issue might stem from several causes: * Burnt net fuses: Check and replace them if necessary. * Damaged supply cable: Repair or replace the cable. * Faulty main switch S001: Inspect the switch's condition. * Faulty auxiliary transformer T002 or bad connections: Check the transformer and connectors, fixing any bad connections or replacing T002 if needed. * Faulty control card A002: Check the control card fuses and replace A002 if necessary.

What to do if the net fuse gets burnt during startup of Kemppi MASTERTIG AC/DC 2500W Welding System?
- D
  David PhillipsAug 27, 2025
  If the net fuse burns during startup of the Kemppi Welding System, consider these possible causes: * A faulty supply cable: Inspect and replace if necessary. * A faulty primary circuit component: Check components like the main switch, primary rectifier, and primary IGBT. * A faulty secondary circuit component: Examine the diode cards, secondary IGBT, and control card A003.

Why fans remain rotating but the panel isn't operating correctly on Kemppi MASTERTIG AC/DC 2500W Welding System?
- P
  pschroederSep 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.
