Why won't my Kemppi Welding System start and the panel signal light (green) is not ignited?
- J
  joegutierrezAug 9, 2025
  If your Kemppi Welding System doesn't start and the green panel light is off, the issue could stem from: * Aux transformer T002: Check the aux. Transformer T002 secondary voltage between connectors X8/1-X8/2 (approx. 23 Vac). * Control card A001: If the aux. transformer secondary voltage is approximately 23 Vac, then replace the control card A001.
