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

Reliable Aluminum Wire Feeding Solutions

Achieving high-quality aluminum welds starts with a reliable wire feeding system. The Lincoln Electric KP1695-040A Drive Roll Kit provides the necessary components to equip your Lincoln MIG welder for .040 inch (1.0 mm) aluminum wire. Aluminum welding requires specific equipment because the wire is much softer than steel or stainless steel. Using incorrect drive rolls can flatten the wire, causing it to drag in the liner or burn back at the tip. This kit utilizes U-Groove technology, which grips the wire gently but firmly, ensuring consistent feed speeds essential for pulse MIG or standard spray transfer modes.

One of the most frustrating aspects of MIG welding aluminum is the potential for feed issues known as bird-nesting. This occurs when the soft wire encounters resistance and buckles immediately after the drive rolls. The KP1695-040A kit mitigates this risk with its included split wire guides. These guides are precision-machined to align perfectly with the U-Groove rolls, guiding the wire directly into the gun receiver bushing with minimal clearance. This support prevents the wire from wandering or kinking, ensuring a smooth transition from the feeder to the welding gun.

Installation is straightforward, allowing welders to switch between steel and aluminum setups quickly. The kit is designed for durability and long service life, manufactured to Lincoln Electric's high standards. It is compatible with a wide range of Lincoln 2-roll wire feeders, making it a versatile addition to any shop that handles aluminum fabrication. By using genuine Lincoln consumables, you ensure that your machine operates at peak performance, delivering the weld quality your projects demand.

Benefits for the Welder:

• Smooth Feeding: Reduces friction and drag, promoting a stable arc.
• Reduced Downtime: Minimizes wire tangles and bird-nests.
• Versatility: Allows standard 2-roll feeders to handle soft alloys effectively.
• Quality Assurance: Genuine Lincoln parts ensure perfect fit and function.
