W4017211 - Lincoln Electric .045-1/16 V-Knurled Drive Roll Kit (Set of 2)

Get a Grip on Your Flux-Cored Welding

Every welder knows the frustration of wire slippage. You pull the trigger, the motor whirs, but the wire stutters or stops completely, ruining your bead and forcing a restart. If you are running flux-cored or metal-cored wire, the solution is often in your drive rolls. The Lincoln Electric W4017211 Feed Roll Set is designed to solve exactly this problem. These aren't your standard smooth grooves; they feature a V-Knurled (VK) design that acts like tire treads for your welding wire. The textured groove grabs onto the shell of .045" and 1/16" tubular wires, pushing them through the liner with authority, even when the cable is bent or long.

Why is V-Knurled important? Tubular wires are hollow and filled with flux or metal powder. If you use standard smooth rolls and crank down the tension to stop slipping, you risk crushing the wire into an oval shape. This deformed wire drags inside the liner and wears out contact tips prematurely. With the W4017211 knurled rolls, you can back off the tensioner. The teeth do the work, not the pressure. This means smoother feeding, less wear on your machine, and most importantly, a consistent arc that lets you focus on the puddle rather than fighting the feeder. This set comes with two rolls, getting you back up and running with a fresh, reliable feed system.

Whether you are welding structural beams, repairing heavy machinery, or fabricating in the shop, consistent wire delivery is key to a quality weld. These rolls are built tough by Lincoln Electric to handle the heat and grit of the job site. They are easy to install and are a direct replacement for worn-out rolls on compatible Lincoln feeders. Don't let a cheap or worn-out drive roll compromise your weld quality. Upgrade to the W4017211 set and experience the difference that positive traction makes on your .045" and 1/16" flux-cored projects.
