What to do if overheating indicator is illuminated on Kemppi Minarc Mig Evo 200?
- MMatthew RichardsonJul 26, 2025
If the overheating indicator is on in your Kemppi Welding System, it means the machine has overheated and reached its maximum operating temperature. The thermostat has shut off the welding power. To fix this, let the unit cool down, and it will automatically reset. Also, make sure the cooling air flow is not blocked. If you have exceeded the machine’s duty cycle, wait for the indicator to turn off. Sometimes, this light can also mean there's an issue with the supply voltage being too low or too high.
