KP3989-1 - Lincoln Electric KP3989-1 Insulated Drive Roll for Magnum PRO AL

Smooth Feeding for Aluminum Welding

Every welder knows that feeding aluminum wire can be one of the most frustrating tasks in the shop. The wire is soft, prone to kinking, and easily shaved by aggressive drive rolls. The Lincoln Electric KP3989-1 Drive Roll is designed to solve these specific challenges when using Magnum PRO AL Push Pull Guns. If you are running 0.035" or 0.040" aluminum wire, this is the drive roll you need to keep your arc smooth and your frustration levels low.

The "insulated" aspect of this drive roll isn't just a buzzword; it is a functional necessity for the Magnum PRO AL series. It ensures that the welding current goes exactly where it is supposed to—into the work—rather than shorting out inside your gun's drive mechanism. This protection helps extend the life of your push-pull gun and provides a more consistent arc start. The grooves are precision-machined to grip the wire firmly enough to push and pull it through the liner, but gently enough to avoid flattening the wire or creating metal shavings that can clog your tip.

Swapping out drive rolls is quick and easy, allowing you to change between 0.035 and 0.040 wire sizes without long downtimes. By using this genuine Lincoln Electric part, you ensure that your equipment performs exactly as the engineers intended. Whether you are welding thin gauge aluminum sheet for a boat hull or fabricating custom automotive parts, reliable wire feeding is the foundation of a good weld. Trust the KP3989-1 to deliver that reliability so you can focus on your puddle control and bead appearance.
