KP52079-052A - Lincoln Electric .052 Aluminum Drive Roll Kit (KP52079 Series)

Optimized Wire Feeding for Aluminum Applications

The Lincoln Electric KP52079-052A Drive Roll Kit is a critical component designed to enhance the performance of Gas Metal Arc Welding (GMAW) systems when utilizing .052-inch aluminum welding wire. In industrial fabrication, the reliability of the wire feed mechanism is paramount, particularly with aluminum, which possesses significantly lower columnar strength than steel. Improper drive roll selection can lead to wire deformation, shaving, and erratic feeding, all of which compromise arc stability and weld integrity. This kit is engineered to address these specific challenges through precise dimensional tolerances and material compatibility.

The drive rolls included in this kit typically feature a U-groove or smooth profile specifically suited for soft alloys. Unlike V-groove rolls designed for hard wires, which bite into the material to generate traction, the rolls in the KP52079-052A kit rely on increased surface area contact to propel the wire without altering its cross-sectional shape. This prevents the formation of metal shavings that can accumulate in the liner or contact tip, a common cause of micro-arcing and burn-backs. By maintaining the structural integrity of the wire as it passes through the feeder, the system ensures a constant Wire Feed Speed (WFS), which is essential for maintaining the desired amperage and deposition rate.

This comprehensive kit includes two drive rolls, accommodating standard two-roll drive systems or serving as a replacement set for four-roll systems. It also comes supplied with the necessary set screws and a hex key, facilitating immediate and proper installation. The inclusion of installation hardware ensures that maintenance personnel can perform changeovers efficiently, minimizing equipment downtime. As a genuine Lincoln Electric OEM part, the KP52079-052A guarantees perfect alignment with the wire guides and inlet mechanisms of compatible Lincoln wire feeders, ensuring a low-friction path for the consumable.

For facilities engaged in heavy aluminum fabrication, such as trailer manufacturing, marine construction, or automotive sub-assembly, the condition of the drive rolls is a key variable in process control. Worn or incorrect rolls are a frequent source of operator frustration and weld defects. Implementing the KP52079-052A kit ensures that the wire feed system operates within its design parameters, delivering the consistency required for code-quality aluminum welds.
