254003 - Miller 4-Pin Circular MS Connector Plug Size 14S

Miller 254003 4-Pin Size 14S Plug

Maintain the reliability of your Miller welding equipment with the Miller 254003 Circular Connector. This specialized component is a 4-pin, cable-mount plug designed to fit Size 14S receptacles found on various Miller power sources and accessories. Engineered to the "MS" (Military Standard) specification, this connector features a durable metal housing that shields the internal connections from physical damage and electromagnetic interference.

The Miller 254003 is typically utilized for low-voltage control signals, such as those used in remote amperage controls, contactor switches, and wire feeder trigger cords. The connector employs solder cup contacts, allowing for a permanent and low-resistance bond between the wire and the pin. This is critical in welding applications where consistent signal transmission is necessary for precise arc control. The solder termination also offers excellent resistance to pull-out forces and vibration, common issues in mobile welding setups.

Installation of this plug requires soldering skills. The rear of the connector is designed to accommodate a cable clamp or backshell (often indicated by the "B/L" or similar designation in parts lists) to provide strain relief, preventing the wires from breaking at the solder joints. By using genuine Miller OEM parts like the 254003, you ensure that the thread pitch, keyway orientation, and pin alignment match your machine's receptacle perfectly, avoiding potential damage to the panel-mount socket.

Don't let a broken connector halt your production. Keeping a spare Miller 254003 in your maintenance kit allows for quick field repairs of crushed or corroded plugs. This component represents the quality and durability expected from Miller Electric, ensuring your welding operations continue smoothly with minimal downtime.
