ESAB Replacement Skirted Control Knob - 1/4 Inch Shaft

Restore Precision Control to Your Welder

There are few things more frustrating in the shop than trying to adjust your welder's settings with a broken, slipping, or completely missing knob. If you are operating ESAB equipment and have lost a control dial, the ESAB 950584 Replacement Skirted Knob is the direct fix you need to get back to welding with precision. Over time, knobs can crack from impact, get lost during transport, or simply wear out from daily use. Trying to turn a bare metal potentiometer shaft with welding gloves is not only difficult but can lead to accidental setting changes or even electrical shorts if the shaft is live or damaged.

This replacement knob is designed specifically for 1/4-inch shafts, which are standard on many ESAB wire feeders and power sources. It features a "skirted" design, meaning the bottom of the knob flares out slightly. This isn't just for looks—the skirt helps cover the nut that holds the control pot to the faceplate, keeping dirt and grime out of the electronics while giving your machine a clean, professional appearance. The plastic material is tough enough to handle the heat and knocks of a busy garage or job site, ensuring it won't brittle and crack after a few weeks of use.

Installation is typically straightforward. Depending on the specific shaft type of your machine, this knob will slide on securely, restoring the grip and leverage you need to dial in that perfect voltage or wire speed. Don't settle for generic knobs from the hardware store that stick out too far or wobble when you turn them. Stick with genuine ESAB parts to ensure your machine looks and functions exactly as the manufacturer intended. Whether you are refurbishing an older unit or just fixing a recent mishap, this small part makes a big difference in your daily welding experience.
