Overview

The Miller 174991 is a genuine OEM pointer knob designed to replace the original control dial on compatible Miller welding equipment. Measuring 1.250 inches in diameter with a 0.250-inch inner diameter, this knob fits directly onto the control shaft and secures with a spring clip mechanism — no tools or adhesives needed. The pointer design allows for clear visual alignment with the marked settings on your welder's control panel, ensuring you can dial in voltage, wire speed, or other parameters with confidence.

Built to Miller's factory specifications, this replacement knob is constructed to handle the heat, vibration, and general wear that welding environments demand. Whether your original knob has cracked from age, melted from heat exposure, or simply gone missing, the 174991 restores full functionality and a factory-original appearance to your machine's control interface. It is a small but essential part that keeps your welder operating as intended.
