KP674-3/64A - Lincoln Electric 3/64" Aluminum Drive Roll Kit for SP-255/WM-255

Optimize Your Aluminum Welding Setup

When it comes to welding aluminum, precision and equipment compatibility are paramount. The Lincoln Electric KP674-3/64A Drive Roll Kit is an essential accessory designed specifically for fabricators and welders using the Lincoln Electric SP-255 or Wire-Matic 255 (WM-255) systems. Unlike steel wire, aluminum is soft and pliable, making it prone to deformation, tangling, and shaving if not fed correctly. This drive roll kit is engineered to address those specific challenges, ensuring that your 3/64-inch aluminum wire is fed smoothly and consistently through the gun liner to the contact tip.

Using the correct drive rolls is critical for achieving high-quality welds. Standard knurled or V-groove rolls designed for hard wires can crush soft aluminum, leading to feeding issues known as "birdnesting" or erratic arc characteristics. The KP674-3/64A features geometry specifically tailored to grip aluminum wire firmly enough to push it without causing damage. This balance of grip and gentleness preserves the integrity of the wire, resulting in a stable arc and cleaner weld deposits. Whether you are working on automotive repairs, boat fabrication, or general aluminum maintenance, this kit ensures your machine performs at its best.

Installation is straightforward, allowing you to switch your machine over to aluminum capabilities quickly. As a genuine Lincoln Electric product, you can trust the manufacturing tolerances and material quality. Genuine parts ensure that the drive rolls fit perfectly onto the drive shaft of your SP-255 or WM-255, preventing slippage and wear on the machine's internal components. Investing in the right drive roll kit is a small step that makes a massive difference in the frustration-free operation of your MIG welder.

By choosing the KP674-3/64A, you are ensuring that your equipment is optimized for the specific metallurgical properties of aluminum. This leads to less downtime clearing jams, less wasted wire, and ultimately, a more professional finished product. Equip your workshop with the right tools for the job and experience the difference that genuine Lincoln Electric accessories make in your daily welding operations.
