OVERVIEW

Upgrade Your Feed with Precision Grip

Struggling with wire slippage or inconsistent feeding when running flux-core? The MK Products 511-0101 Knurled Drive Roll is the solution you need for your Cobra, Python, or Prince XL welding gun. Designed to handle .030" and .035" wires, this drive roll features a textured, knurled groove that grabs the wire firmly, pushing it through the gun with authority. Unlike smooth U-groove rolls used for aluminum, these knurled rolls are the standard choice for steel, flux-cored, and metal-cored wires where extra traction is required to maintain a stable arc.

When you are deep in a weld, the last thing you want is for the wire to stutter or stop. The 511-0101 ensures that your wire feed speed remains constant, allowing you to focus on your puddle control and travel speed. The hardened steel construction means this roll can take a beating and keep on feeding, shift after shift. It is a direct replacement part for MK Products systems, ensuring a perfect fit and hassle-free installation. Whether you are fabricating structural steel or performing maintenance repairs, swapping out a worn drive roll for a fresh knurled one can make an immediate difference in your welding performance.

Don't let a slipping wire ruin your bead. This drive roll is specifically engineered to work with the unique push-pull mechanics of MK guns, providing the necessary force to overcome liner friction without crushing the wire. Keep a spare in your kit to ensure you are always ready to tackle steel and flux-core projects with confidence.
