254007 - Miller 14-Pin Circular Control Plug, Solder Type

Technical Overview of the Miller 254007 Connector

The Miller 254007 is a high-quality circular connector plug designed for the transmission of control signals between welding power sources and peripheral equipment. This component features a standard 14-pin configuration, widely utilized across the Miller Electric product ecosystem for interfaces involving remote foot controls, fingertip controls, wire feeders, and spool guns. The connector utilizes Size 20 contacts, which are optimized for the low-voltage and low-amperage signals typical of potentiometer and contactor control circuits (often 24 VAC).

Constructed with a durable metal shell, this MS-style (Military Standard) connector provides robust protection against the physical abuse common in industrial welding environments. The plug is designed for cable mounting, making it the primary interface on the cord side of the connection. Termination is achieved via solder cups, allowing technicians to create a permanent, low-resistance electrical bond between the cable conductors and the connector pins. This solder-type termination is preferred for its reliability and resistance to vibration-induced failure compared to crimp connections in field-repair scenarios.

Proper installation of the 254007 requires precision soldering to ensure no bridging occurs between the closely spaced Size 20 pins. It is an essential component for MRO (Maintenance, Repair, and Operations) professionals tasked with maintaining the functionality of Miller welding fleets. Whether replacing a crushed plug on a TIG foot pedal or fabricating a custom-length interconnect cable for a boom-mounted wire feeder, this OEM part ensures compatibility with the mating receptacles found on Miller power sources.
