  Your Kemppi Welding System might stop working due to several reasons: * If you're using a gas-cooled gun, it may have overheated. Wait for it to cool down. * A wire feeder may have overheated. Allow it to cool and ensure the welding current cable is properly attached. * The power source could be overheating. Wait for it to cool, and check that the cooling fans are working correctly and that airflow isn't blocked. * Also, check all cables to make sure none are loose.
