The Lincoln Electric K663-2 Aluminum Feeding Kit is an essential accessory for professional fabricators looking to achieve high-quality aluminum MIG welds. Welding aluminum presents unique challenges compared to steel, primarily due to the softness of the wire. Standard steel liners and drive rolls can deform soft aluminum wire, leading to erratic feeding, shaving, and the frustrating phenomenon known as "bird-nesting" where the wire tangles at the drive rolls. This comprehensive kit addresses these issues directly by providing a complete pathway tailored specifically for .035 inch (0.9 mm) aluminum wire.
At the heart of this kit is the non-metallic cable liner. Unlike coiled steel liners that create friction and scrape against soft aluminum, the non-metallic material offers a smooth, low-friction conduit that allows the wire to glide effortlessly from the feeder to the contact tip. This reduction in drag is critical for maintaining a consistent arc and preventing burn-back.
Beyond the liner, the K663-2 includes a specialized drive roll and idle roll set. These rolls are engineered to grip the aluminum wire firmly enough to push it through the gun without crushing or deforming it. The included guide tubes further ensure the wire remains aligned throughout the feeding mechanism. To complete the package, Lincoln Electric provides five (5) contact tips sized specifically for .035" wire, ensuring you have the consumables needed to start welding immediately. Designed for compatibility with SuperGlaze™ aluminum MIG wire, this kit is the OEM standard for converting your compatible Lincoln wire feeder for aluminum applications.
