0558102591 - ESAB Wire Feeder Pressure Arm Assembly

Stop Fighting Your Wire Feeder

There are few things more frustrating in the shop than a wire feeder that just won't cooperate. You pull the trigger, and the wire stutters, slips, or birdnests right at the drive rolls. Often, the culprit isn't the machine itself, but a worn-out pressure assembly. The ESAB Pressure Roller Assembly (0558102591) is the direct replacement part you need to get your ESAB welder running like new again. This is the "upper hand" of your drive system—the part that clamps down on the wire and ensures it gets pushed through the liner to the contact tip smoothly and consistently.

Over time, the bearings in the pressure roller can seize, the spring tension can weaken, or the arm itself can become misaligned due to wear and tear. When this happens, you find yourself constantly cranking down the tension knob just to get the wire to move, which only flattens the wire and causes more feeding issues down the line. By swapping out the old assembly for this genuine ESAB replacement, you restore the proper grip and traction your machine was designed to have. It’s a quick fix that saves hours of troubleshooting and grinding out bad starts.

This assembly is built tough for the daily grind. It handles the pressure required for flux-cored wires and the delicate touch needed for aluminum. Don't let a small mechanical part compromise your weld quality or slow down your production. Keep a spare pressure roller assembly on hand or replace your worn one today to ensure that every time you drop your hood and pull the trigger, you get the smooth, sizzling arc you expect from your ESAB equipment. It’s an investment in frustration-free welding.
