Why is there no welding current in my Fronius Portable Generator, even when the mains switch is on and overtemperature service codes are displayed?

The absence of welding current, despite the mains switch being on and overtemperature service codes being displayed, may be due to several reasons: * **Overload:** Consider the duty cycle of your operations. * **Thermostatic safety cut-out:** Allow the power source to cool down, after which it should automatically restart. * **Limited cooling air:** Ensure the air filter on the rear of the housing is clean and that cooling air ducts are accessible. * **Faulty fan:** If the fan is faulty, it is recommended to contact After-Sales Service.
