Miller RCSP-45 allows you to connect a remote pendant control and utilize additional features beyond standard wire feeder control, such as: reduced voltage wire inching, voltage sensing gun trigger lock, contactor contactor control, and programmable welding schedules. This can come in handy when working on a project that requires precise control over the welding process. For example, if you are welding thin metal, you can use the reduced voltage wire inching feature to slowly feed the wire into the weld pool without causing burn-through.
