Remote polarity detection and control for welding process

Abstract:

A system includes a welding torch, a welding power supply unit, a remote device, and control circuitry. The welding power supply unit is configured to supply power to the welding torch. The remote device is coupled between the welding torch and the welding power supply unit. Additionally, the remote device is configured to detect a polarity of a welding operation. The control circuitry is configured to determine if the detected polarity is appropriate based on one or more welding parameters. Further, the control circuitry is configured to adjust the polarity of the welding operation.
