Abstract

An example welding-type system includes: processing circuitry; and a machine readable storage medium comprising a machine readable instruction, when executed by the processing circuitry, cause the processing circuitry to: control a first switch to disconnect a motor circuit from a motor power source, the motor circuit comprising a wire feed motor and a second switch; control the second switch to permit current to flow while the first switch disconnects the motor circuit from the motor power source during a test period; and in response to feedback indicative of a current through the motor circuit while the first switch is open and the second switch is closed, detecting a fault condition associated with the motor circuit.
