Abstract: Welding power supplies and user interfaces to control output polarity for welding power supplies are disclosed. An example welding power supply includes: a first terminal and a second terminal configured to be connected to welding equipment; power conversion circuitry configured to convert input power to weld power and to output the weld power via the first and second terminals; an interface, including: one or more first input devices configured to receive a selection of a wire feeding weld process; and one or more second input devices configured to receive a selection of a polarity of the weld power; and control circuitry configured to, in response to receiving, via the interface, an input associated with at least one of the wire feeding weld process or the selection of the output polarity, control the polarity of the weld power output via the power conversion circuitry to the first and second terminals.

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.
