Miller 179851 Welding Machine Pointer Knob

The Miller 179851 Welding Machine Pointer Knob is a genuine OEM replacement component designed for use on compatible Miller Electric welding machines. It features a push-on mounting design with an integrated spring that grips onto a 0.250-inch diameter control shaft, providing secure attachment without requiring tools or set screws. The pointer-style knob measures 1.670 inches in diameter, giving you a clear visual reference when adjusting voltage, amperage, or other dial-controlled settings on your welder.

Weighing just 0.03 pounds, this knob is built for manual operation and maintains the same feel and responsiveness as the original factory-installed control. If your existing knob has cracked, lost its pointer marking, or no longer grips the shaft reliably, this direct replacement restores precise, repeatable adjustments. As with any OEM part, it is advisable to confirm part number 179851 against your specific Miller welder's parts diagram to ensure compatibility before purchasing.
