292552 - Miller Replacement Lobed Control Knob 3/8-16 Thread

Genuine Miller OEM Replacement Component

The Miller 292552 is a high-quality replacement lobed knob designed specifically for Miller welding equipment. As a genuine OEM (Original Equipment Manufacturer) part, it guarantees precise fitment and reliable performance, eliminating the guesswork often associated with universal aftermarket components. This knob features a standard .375-16 UNC thread pitch, making it compatible with a variety of control shafts found on Miller power sources and wire feeders. The internal threading is precision-molded to ensure a secure fit that will not strip or loosen under vibration, a critical factor in heavy-duty industrial environments.

The physical configuration of the knob is engineered for utility and protection. It utilizes a "blind" hole design, meaning the threaded cavity does not pass all the way through the top of the knob. This creates a sealed cap over the end of the mounting stud, effectively shielding the threads and the internal component shaft from shop dust, metal shavings, and moisture. With a length of 1.460 inches, the knob provides sufficient standout from the machine faceplate to be easily grasped, yet remains low-profile enough to avoid accidental snagging or breakage during transport.

Material selection for the 292552 prioritizes durability. Constructed from a robust black composite, it is designed to withstand the thermal cycling and UV exposure typical of welding operations. The material resists cracking and fading, ensuring the machine maintains a professional appearance and functional integrity over years of service. Maintenance personnel looking to restore equipment to factory specifications will find this part essential for replacing lost, cracked, or stripped control knobs on compatible Miller units.
