287269 - Miller XR-Alumafeed Tension Adjustment Assembly

Keep Your XR-Alumafeed Running Smoothly

Every welder knows the frustration of a wire feeder that just won't cooperate. You're in the middle of a critical weld, and suddenly the wire slips, the arc stutters, and you're left with a defect to grind out. Often, the culprit isn't the machine itself, but a worn-out tension knob that can no longer hold the setting. The Miller 287269 Tension Knob Kit is the direct replacement you need to get your XR-Alumafeed Suitcase back in fighting shape. These feeders are built for the toughest jobs, often dragged around shipyards and construction sites, and the external knobs can take a beating. Whether yours has been sheared off, stripped out, or just lost its grip, this kit is the fix.

Designed specifically for the XR-Alumafeed, this kit isn't just a generic plastic knob; it's the key to consistent wire delivery. When you are welding aluminum, tension is everything. Crank it too tight, and you crush the wire; leave it too loose, and it birdnests. You need a tensioner that adjusts smoothly and stays put. This genuine Miller part restores that tactile control, allowing you to dial in the perfect pressure for 4043 or 5356 aluminum wire without the guesswork. It is a small part that makes a massive difference in your daily welding experience.

Don't let a ten-dollar problem cause a thousand-dollar delay. Keeping a spare tension knob kit in your job box or maintenance locker is smart planning. Installation is quick and requires no special tools, meaning you can swap it out in the field and get back to burning wire in minutes. Trust genuine Miller parts to maintain the performance and reliability you expect from your blue equipment.
