Miller Pointer Knob 1.250 OD x .250 ID with Set Screws

Restore Your Machine's Precision with the Miller 193919 Knob

There are few things more frustrating in the shop than trying to dial in your voltage or wire speed with a broken, slipping, or missing knob. The Miller 193919 Pointer Knob is the genuine replacement part you need to get your machine back to looking and performing like new. Whether your original knob was lost during transport or simply wore out after years of heavy use, this direct replacement ensures you can make adjustments confidently and accurately. A welder's control panel is their dashboard; keeping it in top shape is key to professional results.

Designed specifically for Miller equipment, this knob features a 1.250-inch diameter that feels substantial in your hand, making it easy to turn even when you are wearing welding gloves. The clear pointer design takes the guesswork out of your settings, allowing you to see exactly where your dial is set at a glance. Unlike cheap universal knobs that might wobble or strip out, this OEM part is built to fit the 1/4-inch shafts on your machine perfectly. It uses two set screws to lock onto the shaft, ensuring that when you turn the knob, the setting actually changes—no more free-spinning dials.

Installation is incredibly simple and takes just seconds with a small Allen wrench or screwdriver (depending on the screw head type). By securing the knob with two points of contact, it stays put even when the machine is vibrating or being moved around the job site. Don't settle for makeshift repairs or pliers that damage the potentiometer shaft. Invest in the correct Miller part to maintain the value and functionality of your welding rig. This package includes one knob with the set screws pre-installed, ready to go right out of the bag.
