KP1695-040A - Lincoln Electric KP1695-040A U-Groove Drive Roll Kit for .040 Aluminum Wire

Optimize Aluminum Feeding with Lincoln Electric KP1695-040A

The Lincoln Electric KP1695-040A Drive Roll Kit is an essential accessory for professional welders working with aluminum applications. Designed specifically for use with Lincoln Electric MIG welders and wire feeders utilizing a two-roll wire drive system, this kit addresses the unique challenges associated with feeding soft aluminum wire. Unlike steel wires, aluminum is prone to deformation and crushing if fed through standard V-groove rolls. This kit features precision-engineered U-Groove drive rolls that cradle the .040 in (1.0 mm) wire, providing positive traction without altering the wire's cross-sectional shape. This ensures consistent electrical contact at the contact tip and a stable arc.

Feeding aluminum wire is often plagued by "bird-nesting," where the wire tangles at the drive rolls due to friction or obstruction in the liner. The KP1695-040A kit includes a specialized split wire guide designed to support the wire as it travels from the drive rolls into the gun liner. This tight tolerance guidance system minimizes the unsupported length of the wire, significantly reducing the likelihood of buckling and tangling. By maintaining a smooth feed path, operators can experience less downtime clearing jams and more time welding.

This genuine Lincoln Electric kit is comprehensive, containing everything needed to convert a compatible 2-roll system for aluminum service. It includes two U-Groove drive rolls and five wire guides, ensuring you have replacement parts on hand for maintenance. Whether you are fabricating aluminum trailers, repairing automotive components, or performing general manufacturing, the KP1695-040A ensures your equipment is optimized for soft wire delivery.
