278903 - Miller 2.0M Power Cord 14GA 3C with NEMA 6-50P Plug

Miller 278903 OEM Power Cable Assembly

The Miller 278903 is a specialized power input cable designed to provide a reliable electrical connection for compatible Miller welding power sources. Engineered to meet strict OEM specifications, this cable assembly features a 2.0-meter (approximately 6.5 feet) length, offering sufficient reach for standard workshop setups while maintaining a tidy workspace. The cable is constructed from high-quality 14 AWG wire with 3 conductors, ensuring durability and consistent power delivery for machines rated for this gauge.

A key feature of this assembly is the pre-molded NEMA 6-50P plug. The NEMA 6-50P is the industry standard for 250V welding outlets, rated for up to 50 Amps. While the 14-gauge wire is designed for the specific current draw of the intended machine (often lower amperage inverters), the inclusion of the 50A plug allows users to plug the machine directly into standard heavy-duty welding receptacles without the need for adapters or electrical modifications. This ensures seamless integration into existing shop infrastructure.

This component is critical for maintaining the safety and performance of your equipment. Using non-OEM power cables can lead to fitment issues, improper voltage drops, or safety hazards. The Miller 278903 ensures that the strain relief, conductor insulation, and plug termination meet the rigorous standards set by Miller Electric for their equipment.
