0558102331 - ESAB Wire Feeder Pressure Arm Assembly

Fix Your Feed Issues Fast

Is your wire slipping? Are you hearing the motor run but seeing the wire hesitate? You might need a new ESAB Pressure Arm (0558102331). The pressure arm is the muscle behind your wire feeder—it's the part that clamps down on the wire, ensuring the drive rolls can grab it and push it through the torch. When this part wears out, cracks, or loses its ability to hold tension, your welding frustrates quickly turn into a nightmare of birdnests and sputtering arcs.

We know that in the shop, time is money. You can't afford to stop every ten minutes to re-feed wire or adjust tension knobs that no longer respond. This genuine ESAB replacement arm is the exact part you need to get your machine running like new again. Because it is an OEM part, it drops right into place without any modification or "making it fit." It restores the firm, consistent grip your drive rolls need to feed solid or flux-cored wire smoothly, even through long torch cables.

Why replace the pressure arm?

• Eliminate Slippage: A fresh arm applies the correct, even pressure across the wire surface.
• Stop Burn-backs: Consistent feeding prevents the wire from stopping unexpectedly in the puddle.
• Protect Your Drive Rolls: Proper tension prevents the rolls from grinding against the wire unnecessarily, extending their life.

Don't let a small plastic or metal part hold up your production. If you've noticed that tightening the tension knob no longer fixes the slip, or if the arm itself is visibly cracked or bent, swap it out immediately. This ESAB 0558102331 Pressure Arm is built to handle the daily grind of the welding shop. Pair it with clean drive rolls and a fresh liner, and you'll feel the difference the moment you pull the trigger. Keep your beads smooth and your downtime low with quality replacement parts.
