KP654-1/16A - Lincoln Electric KP654-1/16A Aluminum Drive Roll & Guide Tube Kit

Smooth Aluminum Feeding with the Lincoln KP654-1/16A

Every welder knows that aluminum can be one of the most frustrating materials to feed through a MIG system. The wire is soft, it bends easily, and if your drive rolls aren't perfect, you're going to spend half your day clearing birdnests out of the feeder. The Lincoln Electric KP654-1/16A Drive Roll Kit is the solution to those headaches for operators using LN-25 or LN-7 series feeders. This kit is purpose-built to handle 1/16-inch (1.6 mm) aluminum wire with the care and precision it requires.

The secret lies in the design of the drive roll and the accompanying guide tube. Unlike knurled rolls that chew up the wire or V-groove rolls designed for hard steel, the roll in this kit is shaped to cradle the aluminum. It provides positive traction to push the wire through the liner without flattening it or shaving off metal flakes that can clog your liner and tip. This means you get a consistent wire speed at the arc, which is absolutely critical for high-quality aluminum welds, especially when dealing with the high thermal conductivity and fast travel speeds associated with the process.

Installation is straightforward, getting you back to welding in minutes. The included guide tube is just as important as the roll itself; it supports the wire right up to the drive rolls, leaving no room for the wire to wander or buckle under pressure. Whether you are welding on a boat, a trailer, or an aerospace component, trusting your feed system is half the battle. With the KP654-1/16A, you can trust that your Lincoln feeder will deliver the wire smoothly, letting you focus on your puddle control and bead appearance.

Don't compromise your welds with generic or incorrect drive rolls. Using the right kit for the material makes a world of difference in arc starts and overall weld consistency. This kit ensures your LN-25 or LN-7 is optimized for aluminum, turning a potentially difficult job into a smooth operation.
