A wire feeder including a motor driving a set of feed rolls to force a welding wire from a spool through a welding torch to a welding operation. The wire feeder has an input lead to be comiected to the output lead of one of a plurality of remotely located power sources, each having a signal receiver for receiving transmitted signal with a code unique to one of the power sources. The receiver having an output for controlling a parameter or condition of the one power source in accordance with a received signal with the unique code. A transmitter on each of said plurality of power sources for transmitting on its output lead a coded signal specific to the power source. A signal receiver on said wire feeder to receive a unique code from the specific power source actually connected to the wire feeder and a circuit on the wire feeder for transmitting command signals fi-om. the wire feeder, which command signals each have the unique code specific to the power source comiected to said wire feeder.
