2-004100.1 - 0.8mm / 1.0mm V-Groove Drive Roll for MIG Wire Feeder

Stop Fighting Your Wire Feeder

There is nothing more frustrating than being in the middle of a bead and feeling the wire stutter or slip. If you are constantly adjusting your tension knob or dealing with burn-backs, your drive rolls might be the culprit. The Car-O-Liner 2-004100.1 Drive Roll is the direct replacement you need to get your machine running smoothly again. Designed with a reversible dual-groove system, it handles the two most common wire sizes we use in the shop: 0.8mm and 1.0mm.

This isn't just a piece of metal; it's the traction control for your welder. The V-Groove design is specifically made for solid wires like ER70S-6 or stainless grades. It provides the necessary friction to push the wire through the liner and out the gun without crushing it. If you've been trying to run solid wire with worn-out rollers or the wrong groove type, you know the headache of erratic feeding. Swapping in a fresh 2-004100.1 roller eliminates that variable, giving you a consistent wire speed that lets you focus on your puddle control rather than fighting the machine.

Durability matters in a busy shop. These rollers are made from hardened steel to resist the grooving and wear that eventually kills cheaper rollers. The reversible design is a huge plus—if you mostly weld with 0.8mm and that groove eventually wears out, you can often flip it (if you haven't used the 1.0mm side) or simply use it to switch between jobs quickly. Don't let a cheap consumable ruin your welds. Keep a spare 2-004100.1 in your toolbox and ensure your wire delivery is as smooth as your technique.
