Abstract
Disclosed are welding systems and methods for conducting a completed circuit testing process. The welding system includes a power source to deliver power via one or more power outlets. Control circuitry receives an input to initiate a welding process and to command the power source to deliver a power signal with a current below a threshold level. The control circuitry monitors characteristics of the power signal at the one or more power outlets and determines whether a completed circuit condition exists. The control circuitry performs this determination based on information obtained through monitoring the characteristics of the power signal. The control circuitry controls the power source to prevent delivery of power if a completed circuit condition exists.
