Is a damaged connector stopping you from getting the job done? The Miller 212378 19-Pin CPC Plug is the exact replacement part you need to fix broken control cables and get back to welding. In the world of welding, communication between your power source and your accessories—like wire feeders, remote controls, and foot pedals—is critical. A smashed or corroded plug can cause erratic wire feeding, loss of arc control, or complete machine failure. This genuine Miller replacement part ensures you restore factory-level performance to your rig.

This connector is a 19-pin, Size 23 Circular Plastic Connector (CPC), a standard format used across many Miller systems for its reliability and durability. It is designed as a cable-mount plug, meaning it attaches to the end of your control cord to mate with the receptacle on your machine or extension. The push-in design facilitates a secure connection for the internal pins, helping to prevent loose connections that can cause frustrating intermittent faults while you are trying to lay a bead.

Don't risk your weld quality or your machine's electronics with generic, ill-fitting connectors. The Miller 212378 is built to the tight tolerances required for Miller equipment, ensuring a weather-resistant and secure fit when mated. Whether you are a maintenance technician repairing a fleet of machines or a fabricator fixing your own gear, this plug is the professional choice for electrical repairs.
