37319 - Esab .045/.052 Knurled Drive Roll for MigMaster and MobileMaster Feeders

Get a Grip on Your Flux Core Wire

If you are running flux-cored or metal-cored wire through your Esab machine, you know that feeding issues can ruin your day. Slipping wire leads to burn-backs, stuttering arcs, and frustration. The Esab 37319 Knurled Drive Roll is the solution. Specifically designed for .045" and .052" tubular wires, this roller features jagged teeth (knurling) that grab onto the wire's surface. This allows you to back off the tensioner, saving your wire from being crushed into an oval shape, which causes drag in the liner and contact tip issues.

This is a genuine Esab part, meaning it drops right into your MigMaster 250, 251, 300i, or MobileMaster feeder without any hassle. It’s a reversible roll, giving you two size options in one durable piece of steel. If you switch between .045 and .052 wire often, you just flip the roll around. No need to keep track of multiple parts. The hardened steel construction means these teeth stay sharp longer, keeping your production line moving and your welds consistent.

Don't let worn-out smooth rolls or the wrong groove type compromise your welds. Using smooth V-grooves on flux core often requires too much tension to get a grip, which flattens the wire and clogs your tip. Switching to the 37319 Knurled Roll lets the machine do the work properly. It is an affordable upgrade or maintenance replacement that pays for itself by eliminating feed stoppages. Keep your arc smooth and your bead straight with the right hardware for the job.
