KP1507-040A - Lincoln Electric .040 Aluminum Drive Roll & Guide Tube Kit (4-Roll)

Smooth Aluminum Feeding with Lincoln Electric

Welding aluminum can be a test of patience, primarily due to the difficulties associated with wire feeding. The Lincoln Electric KP1507-040A Drive Roll Kit is designed to take the frustration out of the equation. If you are running .040 inch (1.0 mm) aluminum wire, this kit is the upgrade your machine needs to deliver consistent, trouble-free performance. Unlike standard rolls that might crush soft aluminum or allow it to wander, these rolls are crafted to grip the wire gently yet firmly, ensuring it moves smoothly from the spool to the contact tip.

Why the 4-Roll System Matters

This kit is designed for 4-roll wire feeder systems, which are superior for aluminum applications. By using four rolls instead of two, the feeder can push the wire with more surface area contact. This means you don't have to crank down the tension knob, which often leads to flattened wire and excessive shavings clogging your liner. The result is a steady wire speed that helps you maintain a consistent arc length and produce high-quality, aesthetic welds that aluminum projects demand.

Complete Feeding Solution

The KP1507-040A isn't just about the rolls; it also includes a specialized guide tube. This component is often overlooked but is vital for preventing "bird-nesting"—the tangled mess of wire that happens when the wire hits resistance and buckles before entering the gun cable. The guide tube supports the wire right up to the rolls, leaving no room for it to kink. Whether you are working on automotive repairs, marine fabrication, or custom aluminum projects, installing this genuine Lincoln Electric kit ensures your equipment is tuned for success, letting you focus on the puddle rather than fixing feed jams.
