Abstract
Systems and methods of the present invention are directed to welding systems having a welding power supply and wire feeder, where the power supply and wire feeder communicate over the welding power cables. In exemplary embodiments, the wire feeder communicates with the power supply over the welding cables using current draw pulses which are generated and recognized by the power supply. Similarly, the power supply generates voltage pulses which are transmitted over the welding power cables and recognized by the wire feeder.
