Classification: CPC B | IPC B

Claim 0:
1. A welding-type system, comprising:
a wire feeder configured to provide an electrode wire to a welding-type torch; and
a welding-type power supply configured to:
provide welding-type output power to the welding-type torch and the wire feeder during a welding-type operation; and
during a non-arc period, provide power to the wire feeder as a pulsed output signal, the welding-type power supply comprising a controller configured to:
monitor the pulsed output signal of the welding-type power supply, the pulsed output signal to provide power sufficient to operate the wire feeder;
calculate a change in the pulsed output signal to the wire feeder based on the monitored pulsed output signal;
determine whether the wire feeder is activated or deactivated based on the change in the pulsed output signal to the wire feeder; and
control the welding-type power supply to adjust a pulse interval of the pulsed output signal to the wire feeder from a first RMS value to a second RMS value that is within a predetermined threshold RMS range based on the determination that the wire feeder is deactivated by extending the pulse interval of a low voltage level of the second RMS value to achieve the predetermined threshold RMS range.
