222094 - Miller GFCI Receptacle Ivory with Capacitor

Reliable Auxiliary Power for Miller Generators

The Miller 222094 GFCI Receptacle is a critical replacement component designed specifically for Miller engine-driven welding generators. Unlike standard residential outlets found at local hardware stores, this OEM part is engineered to handle the unique electrical environment of a welding machine. The unit comes in a standard Ivory color and features a straight blade duplex configuration, allowing operators to power tools, lights, and grinders directly from their welder.

Why the Capacitor Matters

The defining feature of the Miller 222094 is the inclusion of a specialized capacitor. Welding generators, while powerful, often produce "dirty" power characterized by harmonic distortion and high-frequency electrical noise. Standard Ground Fault Circuit Interrupters (GFCIs) are highly sensitive to these irregularities and often suffer from "nuisance tripping"—cutting power when no actual ground fault exists. The integrated capacitor on this Miller receptacle acts as a filter, smoothing out the noise and ensuring the GFCI only trips when a genuine safety hazard is detected. This ensures your auxiliary tools stay powered without constant interruptions.

OEM Quality and Safety

Safety on the job site is paramount, and maintaining functional GFCI protection is a requirement for OSHA compliance. This receptacle provides essential protection against electric shock in wet or conductive environments often encountered in field welding. As a genuine Miller Electric part, it guarantees a perfect fit for the mounting panel of compatible machines (such as Bobcats and Trailblazers) and withstands the heavy vibration associated with engine operation. Using non-OEM substitutes can lead to loose connections, melted terminals, or persistent power failures.

Installation and Compatibility

This receptacle is designed for 120V AC applications. It is a direct replacement for the original ivory outlet found on many Miller machines. When replacing your old receptacle, ensure the machine is off and locked out. The pre-wired capacitor simplifies installation, ensuring you restore the machine to factory specifications for both performance and safety.
