0445850002 - ESAB V-Groove Drive Roll 0.030/0.040 Solid Wire

Keep Your Wire Running Smooth

We've all been there: you're in the middle of a long bead, and suddenly the gun starts sputtering. It feels like the machine is losing power, but nine times out of ten, it's a feeding issue. If your drive rolls are worn out, the wrong size, or the wrong type, you're going to fight your machine all day long. The ESAB Feed Roller V 0.8/1.0 is the fix you need if you are running solid steel or stainless wire. This isn't just a spare part; it's the heartbeat of your wire feeder.

This roller features a classic V-Groove design. Why does that matter? Because if you use a knurled roller on solid wire, you chew up the copper coating, creating dust that clogs your liner. If you use a flat roller, you have to crank the tension so high you flatten the wire. The V-groove cradles the wire perfectly, giving you grip without the crush. This specific roller is a two-in-one deal. One side is machined for 0.030" (0.8mm) wire, and the other handles 0.040" (1.0mm). Changing sizes is as easy as taking the roller off, flipping it around, and sliding it back on.

Durability is key in a shop environment. These rollers are made from hardened steel, so they don't groove out after a few spools. A worn roller will cause the wire to slip, leading to burn-backs where the wire fuses to your tip—a massive waste of time and consumables. By keeping a fresh ESAB 0445850002 in your feeder, you ensure that the wire speed you set is the wire speed you get. It’s a small investment that saves you from the headache of birdnesting and erratic arcs.

Whether you are fabricating structural steel, doing automotive bodywork, or general repairs, this roller covers the two most common wire sizes you'll likely use. Don't let a twenty-dollar part ruin a thousand-dollar job. Check your rollers, and if they look worn or if you're switching wire sizes, swap in this genuine ESAB drive roll to get back to stacking dimes.
