Claims20
A welding system, comprising:
- a power source configured to generate power and deliver the power to a welding electrode, wherein the power source comprises a positive stud and a negative stud;
- and
- control circuitry configured to determine whether the welding electrode is properly connected to the positive and negative studs of the power source.
A method, comprising:
- applying a test voltage across positive and negative studs of a power source;
- detecting voltages at the positive and negative studs;
- and
- determining if a welding electrode is improperly connected to the positive stud or the negative stud by comparing the detected voltages.
