  • EXTERNAL CONNECTOR AND SENSOR UNIT FOR WELDING EQUIPMENT
    Publication number: 20220075003
    Abstract: A connector and sensor unit for a welding apparatus, including a first port configured to be connected to a first welding cable of the welding apparatus, a second port configured to be connected to a second welding cable of the welding apparatus, current sensor circuitry configured to sense a current being supplied by the first welding cable and the second welding cable, and to output a corresponding current sense signal, voltage sensing circuitry configured to sense a voltage between the first welding cable and the second welding cable, and to output a corresponding voltage sense signal, and supply power circuitry configured to generate a predetermined voltage for at least the current sensor circuitry, wherein the supply power circuitry receives power from the first welding cable and the second welding cable via at least one inductor.
    Type: Application
