What to do if AUTO ARC Toolmate 100 has no weld output and wire feed but the fan runs?
- Jjason89Aug 11, 2025
If your AUTO ARC Welding System has no weld output, and the wire does not feed, but the fan motor continues to run, try the following: * Allow the fan to run with the gun trigger switch off to cool the unit if thermostat TP1 is open due to overheating. The thermostat will close when the unit has cooled. * Ensure the Voltage switch is set to positions 1, 2, 3, or 4, as there's no weld output or wire feed in the Fan Only position. * Make sure the gun trigger switch is fully depressed and held. * If the Over Temperature Light PL1 is illuminated, allow the fan to cool the unit until the light turns off. This indicates the unit has overheated.
