What to do if there is no weld output but wire feeds on Miller Electric Welding System?
- DDeborah BestJul 31, 2025
If your Miller Electric Welding System isn't producing any weld output and the wire is feeding, several factors could be at play. First, the thermostat TP1 might be open due to overheating; allow the fan to run so the unit can cool down and the thermostat will close. Ensure the work clamp has good metal-to-metal contact. It could also be a worn contact tip, so replace it. If an overload occurred, release the gun trigger. If these steps don't resolve the issue, have a Factory Authorized Service Agent check the main control board and main rectifier.
