0418090001 - ESAB Wire Feeder Pressure Tension Spring 0418090001

Keep Your Welder Running Smoothly

Every welder knows the frustration of a wire feeder that just won't cooperate. You pull the trigger, and the wire slips, stutters, or feeds unevenly, ruining your bead and your rhythm. Often, the culprit isn't the motor or the liner—it's a simple, worn-out spring. The ESAB 0418090001 Pressure Spring is the direct replacement you need to get your machine back to feeding like it did on day one.

This spring sits inside your wire drive assembly and is responsible for pushing the pressure roller down onto the wire. If it's old or tired, it can't apply enough pressure, causing the drive rolls to spin without moving the wire. Cranking down the tension knob to compensate is a bad habit that can flatten your wire and cause it to shave off inside the liner, leading to even more headaches down the road. The smart fix is to simply replace the spring.

Designed specifically for ESAB equipment, this spring drops right into place without any modification. It restores the snappy, firm tension you need for consistent feeding, whether you are running solid wire or flux-cored. It’s built tough to handle the daily grind of a welding shop, ensuring that once you swap it out, you won't have to worry about it for a long time.

Don't let a five-dollar part cost you hundreds in lost time and frustration. If your tension knob feels loose or your wire is slipping, check your pressure spring. Upgrading to a fresh ESAB 0418090001 is a quick, easy maintenance task that pays off immediately with a stable arc and smooth wire delivery. Keep your focus on the puddle, not the feeder.
