KP3990-1 - Lincoln Magnum PRO .035 Insulated Knurled Drive Roll

Keep Your Wire Moving Smoothly

Nothing ruins a weld faster than a slipping wire. If you are running a Lincoln Magnum PRO setup and need reliable feeding for .035" wire, the KP3990-1 Drive Roll is the part you need. This isn't just a smooth wheel; it features a knurled surface that bites into the wire just enough to push it through the liner without slipping, even when the cable gets twisted or you're welding in an awkward position. Consistent feeding means a consistent arc, and that means better beads with less frustration.

This drive roll is also insulated, which is a big deal for keeping your gun running safely. The insulation stops the welding current from traveling where it shouldn't, protecting your feeder's motor and gears from electrical damage. It's a small part that does a big job in keeping your rig operational. Whether you are replacing a worn-out roll or setting up a gun for a specific job, this genuine Lincoln part ensures everything fits perfectly and works right out of the box.

Don't let feed issues slow down your production. The KP3990-1 is built tough to handle the daily grind of the shop. It swaps out easily, so you can get back under the hood fast. Trust Lincoln Electric parts to keep your Magnum PRO system firing on all cylinders, delivering the performance you expect from top-tier equipment.
