Abstract
A method of operating a welding wire feeder includes receiving an input power from a welding power source, actuating a power relay to close and open a first current carrying path for application of the input power, and actuating bypass circuitry coupled in parallel to the power relay to close and open a second current carrying path in coordination with actuating the power relay. The method of operating the welding wire feeder also includes providing a welding wire to a welding torch.
