Abstract

A welding-type system includes a wire feeder to provide an electrode wire to a welding-type torch. A welding-type power supply to provide power to one or both of the welding-type torch or the wire feeder. A controller is configured to control a sense voltage circuit to provide a sense voltage to charge a control capacitor, monitor a voltage feedback signal, determine that a wire feeder is activated based on a first change in the voltage feedback signal, control the switched mode power supply to provide a constant voltage output signal during a welding operation, control the switched mode power supply to provide the pulsed power output in response to completion of the welding operation, determine that the wire feeder is deactivated based on a second change in the feedback signal, adjust a pulse rate of the output signal to achieve an RMS value below a predetermined RMS level.
