WELDING SYSTEM DEVICE DETECTION

Abstract: a welding system includes a welding power supply, wire feeder, and welding circuit connecting the power supply to the wire feeder. the power supply and the wire feeder are configured for bidirectional communication over the welding circuit. the power supply includes a voltage sensor that measures a voltage level, and a current sensor that measures a current level, on the welding circuit. the power supply is configured to operate in a first welding mode to output a power voltage level to the welding circuit to power the wire feeder in response to a communication from the wire feeder over the welding circuit. the power supply generates periodic voltage dip pulses on the welding circuit, and automatically switches to a second welding mode different from the first welding mode based on the voltage level on the welding circuit falling below a threshold voltage level during a voltage dip pulse.
