0455896001 - ESAB Wire Feeder Pressure Arm Spring

Keep Your Wire Running Smoothly

There is nothing more frustrating than a wire feeder that just won't feed right. You check your liner, you change your tip, but the wire still slips or stutters. Often, the culprit is a small, tired spring in your drive roll assembly. The ESAB 0455896001 Spring is the exact replacement you need to get that tension back where it belongs. When the spring in your pressure arm gets weak, the drive rolls can't grip the wire hard enough, leading to inconsistent feeding and a sputtering arc that ruins your bead.

Don't let a five-dollar part cost you hundreds in wasted time and frustration. This genuine ESAB spring is built to the exact specs of your machine, meaning it's not too stiff and not too soft—it's just right. It provides the perfect amount of down-pressure on your drive rolls to push that wire through the torch liner smoothly, whether you are running solid MIG wire or flux-core. Installing it is usually a quick fix that you can do right in the shop, getting you back under the hood and burning metal in no time.

Using genuine parts like this spring means you aren't fighting with components that don't fit quite right. It drops right into the pressure assembly of compatible ESAB feeders. If you've noticed you have to crank your tension knob tighter and tighter just to get the wire to feed, it's time to swap out the spring. A fresh spring restores the mechanical advantage of your feeder, allowing you to set the tension correctly without crushing the wire.

Grab a couple of these for your toolbox. It's one of those small parts that can shut down a whole job if it breaks, and having a spare on hand is the mark of a pro who is ready for anything. Keep your arc smooth and your puddles wet with the right maintenance parts.
