What to do if Hobart Welding System has no weld output, wire doesn't feed, but fan motor runs?
- A
  Aaron HartmanAug 30, 2025
  If your Hobart Welding System exhibits these symptoms, it could be due to a few reasons. First, the thermostat TP1 might be open due to overheating; in this case, allow the fan to run with the gun trigger switch off until the unit cools down and the thermostat closes. Also, ensure the Voltage range switch is correctly positioned by rotating the knob until it clicks into place at the desired range setting. Finally, check and secure the gun trigger leads.
