Miller Replacement Control Knob Pointer Assembly

Fix Your Rig with a Genuine Miller 228400 Control Knob

There is nothing more frustrating than trying to dial in your welder when the control knob is cracked, spinning loosely, or missing entirely. The Miller 228400 Knob, Pointer Assembly is the exact replacement part you need to get your machine back to looking and feeling brand new. We know that welding gear takes a beating. Between being tossed in the truck, hit by sparks, or just used every single day with heavy gloves, the plastic knobs on the front of your machine are often the first things to show wear. But a broken knob isn't just an eyesore; it's a hindrance to your workflow.

This isn't just a generic piece of plastic; it's the official Miller pointer assembly. That means it features the correct indicator mark to line up with your machine's settings. When you turn the dial to "20 Volts" or "300 IPM," you want to know that's exactly what you are getting. Using pliers to turn a bare shaft or struggling with a slipping knob is a waste of time and can lead to inconsistent welds if your settings drift. This knob offers the textured grip and precise fitment that Miller operators expect.

Swapping out a damaged knob is one of the easiest and cheapest repairs you can do to extend the life of your welder. It protects the potentiometer shaft underneath from damage and moisture intrusion. Whether you are refurbishing an older shop machine or fixing a field unit that took a knock, the Miller 228400 is the right part for the job. Don't settle for "close enough" hardware store fixes that fall off in a week. Stick with the brand that built your machine and keep your arc smooth and your settings accurate.
