Miller Replacement Lobed Control Knob 3/8-16 Thread

Restore Control to Your Welder

There are few things more frustrating on a job site than trying to adjust your voltage or wire speed with a pair of pliers because a control knob has broken off. The Miller 292552 Replacement Knob is the quick and easy solution to get your machine back to full functionality. Designed with the welder in mind, this knob features a "lobed" shape—a series of rounded protrusions around the circumference—that provides excellent torque and grip. This design is particularly important when you are wearing thick welding gloves; it allows you to make precise adjustments to your settings without having to take your gloves off, keeping you safe and efficient.

This is a genuine Miller part, not a cheap generic knock-off. It is built to the exact specifications of your machine, featuring a .375-16 thread that screws smoothly onto the control stud. The "blind" design means the top is solid, so it covers the metal shaft completely, giving your machine a clean, finished look while keeping grime out of the mechanism. At nearly 1.5 inches long, it is substantial enough to grab easily but tough enough to handle the rough environment of a fabrication shop or field site.

Don't let a small broken part slow down your production or compromise your weld quality due to inability to fine-tune your settings. Whether you are refurbishing an older machine or just fixing a recent mishap, swapping out a damaged knob is one of the simplest repairs you can perform. Simply unscrew the old fragment (if any remains) and thread this new black lobed knob into place. It’s a small investment that makes a big difference in the daily usability of your Miller equipment.
