Why Unitor Welding System has no output and a yellow warning light?
- TTheresa PattersonJul 31, 2025
The Unitor Welding System might show no output and a yellow warning light due to several reasons: * Voltage protection might be activated because the input voltage is too high (it should be below 285V AC). * Thermal protection could be activated if the system was used at too high a duty cycle. In this case, wait for the machine to cool down. You can weld with more breaks or at a lower current. * Cooling airflow may be obstructed; remove any obstructions. * Heat may be developing in loose electrode holder or ground cable connections. * The fan might be broken; repair or replace it. * There might be too much dirt in the power source compartment; clean it out.
