KP1958-6 - Lincoln Electric Magnum PRO Aluminum Liner .035-3/64 15ft

Optimized Aluminum Wire Feeding Solution

The Lincoln Electric KP1958-6 Aluminum MIG Gun Liner is a specialized component engineered to address the unique challenges of feeding aluminum welding wire. Unlike standard steel liners, which can cause excessive friction and wire shaving, this liner is constructed from low-friction materials designed to preserve the integrity of soft aluminum alloys. It is specifically calibrated for wire diameters between .035 inches and 3/64 inches (0.9 mm to 1.2 mm), ensuring precise guidance from the feeder to the contact tip.

With a total length of 15 feet (4.6 meters), the KP1958-6 is compatible with Lincoln Electric's Magnum PRO series MIG guns. The liner's composition minimizes drag, which is critical for maintaining a stable arc and preventing "bird-nesting" at the drive rolls—a common issue in aluminum MIG welding. By providing a smooth, consistent path for the wire, this liner enhances the overall efficiency of the welding system and reduces the frequency of maintenance stoppages.

This genuine Lincoln Electric part ensures dimensional accuracy and seamless integration with existing equipment. It is an essential consumable for industries requiring high-quality aluminum welds, such as automotive manufacturing, aerospace, and marine fabrication. Proper installation and regular inspection of the liner are recommended to ensure optimal performance, as wear or debris accumulation can impact wire feed speeds and weld quality.

The KP1958-6 represents Lincoln Electric's commitment to providing tailored solutions for specific material applications. By utilizing the correct liner for the base material, operators can achieve superior weld bead aesthetics and structural integrity, maximizing the capabilities of their Magnum PRO welding systems.
