The Miller WC-115A weld control with contactor operates on 115V power with constant current DC power sources. This can also be used with constant voltage power sources or DC engine drives supplying 115V. Used with a CC source, the control circuit functions in a voltage-sensing mode and with a CV source, it functions as a constant speed circuit. The control box includes wire run-in and drive motor acceleration controls which ensure optimum arc starting performance.
This is the correct control box for Miller Bobcat Generators utilizing a spoolmatic spoolgun.
