Miller 287164 Circuit Card Assembly: Power/Aux Regulator W/Program

Keep your Miller engine drive running at peak efficiency with the Miller 287164 Circuit Card Assembly. This is a genuine Miller Electric replacement part, specifically designed to serve as the Power and Auxiliary Regulator for compatible machines, such as the Bobcat series. If your welder is experiencing issues with voltage regulation, inconsistent arc starts, or failure to generate auxiliary power for your job site tools, a faulty control board is often the culprit.

The 287164 assembly is a sophisticated piece of electronics that arrives pre-programmed. This is a significant advantage for repair technicians, as it removes the need for specialized programming tools or software downloads during installation. The board is ready to communicate with your welder's system immediately upon installation. It precisely controls the field current to the generator, ensuring that your output voltage remains constant under varying loads, which is vital for high-quality welds and protecting sensitive power tools plugged into the generator outlets.

Welders Supply provides only authentic Miller parts to ensure durability and performance. Circuit boards in engine-driven welders are subjected to harsh conditions, including heat, dust, and vibration. The Miller 287164 is built with robust components and conformal coating where necessary to resist these elements. Replacing a damaged board with this OEM part restores your machine's reliability, ensuring you can get back to work without worrying about power fluctuations.

Technical Compatibility

Please verify your machine's serial number against the parts manual to ensure the 287164 is the correct board for your specific unit. This part is most commonly associated with the Miller Bobcat 260 and related models requiring a programmed power/aux regulator.
