What to do if my Kemppi KEMPOMIG 4000 fuses blow during machine startup?
If the fuses blow during the startup of your Kemppi Welding System, it could be due to several reasons. Check the primary rectifier and IGBT-module condition, as a faulty primary side power semiconductor might be the cause. Inspect the main circuit card for any signs of insulation damage. Also, check the auxiliary transformer and the secondary diodes for faults.
Why won't my Kemppi KEMPOMIG 4000 start and the displays remain blank?
If your Kemppi Welding System won't start and the displays are blank, the issue could stem from several causes. First, check the net fuses. If they are fine, inspect the supply cable and the main switch. Also, check the auxiliary transformer and the intermediate cable between the power source and the WF-unit.
What to do if Kemppi KEMPOMIG 4000 power source stays on MMA when MIG is selected?
If your Kemppi Welding System's power source remains on MMA even when MIG is selected on the panel, the issue may be with the flat cables or the synergy card. Check the flat cables and connectors between the control card A001 and the operating panel. Try disconnecting the flat cable from the P002 synergy card; if the power source then switches to MIG, replace the P002 card.
What to do if my Kemppi Welding System welds but the displays remain blank?
If your Kemppi Welding System is welding, but the displays remain blank, the problem may be with the flat cables or the operating panel. Check the flat cables and connectors between the control card A001 and the operating panel. If the cables are not the issue, replace the operating panel.
