0445850030 - ESAB V-K Knurled Drive Roll 1.0mm/1.2mm for Flux-Cored Wire

Get a Grip on Your Flux-Cored Welding

If you are running flux-cored or metal-cored wire through your ESAB feeder, you know that standard smooth rollers just don't cut it. They slip, they slide, and if you crank down the tension to compensate, you end up crushing the wire and causing feeding issues down the liner. That's where the ESAB 0445850030 Feed Roller V-K comes in. This is the "teeth" your machine needs to push tubular wire consistently, hour after hour.

This roller features a knurled groove—think of it like the tread on a tire—that grabs onto the wire without needing a massive amount of pressure. This means your wire stays round, your liner stays clean, and your arc stays smooth. No more stuttering starts or varying wire speeds ruining your bead appearance. Whether you are welding structural steel or heavy equipment, consistent wire delivery is half the battle, and these rollers win that battle for you.

One of the best features of this roller is its versatility. It's a two-in-one tool. One side is sized for 1.0mm (.040") wire, and the other is sized for 1.2mm (.045") wire. If you need to swap wire sizes for a different job, you don't need to go hunting for a different part box; just take the roller off, flip it around, and you are ready to rock. It’s a simple, time-saving design that makes life in the shop just a little bit easier.

Don't let worn-out or incorrect drive rolls hold back your production. Using the right roller for the wire type is Welding 101, but it's often overlooked. If you see metal shavings piling up under your feeder or feel the wire surging, check your rollers. Upgrading to fresh, genuine ESAB knurled rollers is one of the cheapest ways to improve your weld quality and reduce frustration. Keep a spare set in your toolbox so you're never caught off guard.
