The Miller 254808 is a specialized power input cord set designed for specific 250-volt welding applications. Engineered to meet the rigorous standards of Miller Electric, this component ensures a safe and reliable electrical connection between the power supply and the welding machine. The assembly features a 7-foot length, providing sufficient reach in standard workshop environments without creating excessive slack that could become a tripping hazard. The core of the cable consists of 12 AWG (American Wire Gauge) copper conductors in a 3-conductor configuration (hot, hot, ground), optimized for single-phase 230/250V power transmission.
A key feature of this cord set is the factory-molded NEMA 6-50P plug. The NEMA 6-50 standard is the prevalent configuration for 250V, 50-amp welding circuits in North America. The molded design offers superior strain relief compared to field-installed replacement plugs, preventing internal wire separation at the connection point during frequent handling. The plug's solid brass blades ensure low-resistance contact, minimizing heat generation at the receptacle. It is important to note that while the plug fits a 50-amp receptacle, the 12 AWG wire sizing is engineered based on the specific duty cycle requirements of the compatible welding power source, in accordance with NEC Article 630 provisions for welding equipment.
The cable is encased in an SPT-3 jacket. SPT (Service Parallel Thermoplastic) is a flat, parallel cord construction that offers a balance of flexibility and durability. The "-3" designation indicates a heavy-duty insulation thickness, providing enhanced protection against abrasion, cuts, and environmental factors compared to lighter SPT-1 or SPT-2 cords. This construction makes the cord suitable for the indoor environments typical of light industrial or garage settings where these welders are often employed. Using genuine Miller replacement parts like the 254808 ensures that the replacement cord matches the thermal and electrical specifications of the original equipment, maintaining the machine's safety listing and performance integrity.
