Why does my Fronius TransSteel 2200 Power Supply have no welding current?

If your Fronius Power Supply has no welding current, it might be due to overloading. In this case, observe the duty cycle. Another cause could be that the thermal automatic circuit breaker has tripped. If so, wait for the power source to automatically come back on after the cooling phase. It could also be due to a limited supply of cooling air, so clean the air filter and ensure accessibility to the ventilation openings. If the fan in the power source is faulty, contact After-Sales Service.
