System and method for conditioning an output of a welding type power supply

A welding-type system, comprising:

• a wire feeder to provide an electrode wire to a welding-type torch;
• and
• a welding-type power supply, comprising:
• a switched mode power supply configured to output power to one or both of the welding-type torch or the wire feeder;
• a sense voltage circuit configured to output a sense voltage signal separate from the power provided by the switched mode power supply;
• and
• a controller configured to:
• control the sense voltage circuit to output the sense voltage signal to an output of the power supply for the wire feeder;
• monitor a voltage feedback signal associated with the sense voltage signal at a voltage sensor over a predetermined period of time;
• determine if a value of the voltage feedback signal is increasing during the predetermined period of time;
• determine whether the wire feeder is activated or deactivated based on a change in the voltage feedback signal;
• receive an indication that the voltage feedback signal is increasing;
• control the switched mode power supply to provide a first pulsed power output after the predetermined period of time to operate the wire feeder in response to a determination that the wire feeder is activated;
• or
• in response to receiving an indication that the voltage feedback signal is not increasing, control the sense voltage circuit to continue to generate and provide the sense voltage signal and continue to monitor the sense voltage signal in response to the determination that the wire feeder is deactivated, wherein the sense voltage signal is separate from the first pulsed power output;
• and
• in response to detecting an arc, control the switched mode power supply to output a welding-type power output after the predetermined period of time.
