What to do if Kemppi WeldForce KPS 3500 MVU power source doesn't reach maximum power?
If your Kemppi Welding System's power source isn't reaching its maximum power, begin by inspecting the net fuses and supply cable. Then, check the primary rectifier VG101 and examine the condition of the secondary diode cards.
How to fix Kemppi WeldForce KPS 3500 MVU when the power source will not start?
If the Kemppi Welding System power source won't start and the signal lamps remain blank, check the net fuses, and ensure all 3 phases are correctly connected to the power source's connector X1. Also, verify the auxiliary transformer's secondary voltages from control card A001, between connectors X12 - X11 and X12 - X10 (approximately 20 VAC). Try updating the control card’s flash memory program. If reprogramming doesn't resolve the issue, consider replacing the control card A001.
What to do if net fuses blow immediately when Kemppi WeldForce KPS 3500 MVU is switched on?
If the net fuses blow immediately when you switch on the Kemppi Welding System power source, check the semiconductors on the primary side, as a faulty primary circuit semiconductor may be the cause.
