KP2744-035A - Lincoln Magnum PRO Copper Plus Contact Tip .035 Aluminum (10-Pack)

Advanced Metallurgy for Aluminum Welding

The Lincoln Electric KP2744-035A Copper Plus® Contact Tip is a premium consumable designed specifically to address the unique challenges of welding with aluminum wire. Aluminum has a higher coefficient of thermal expansion than steel, which can often lead to feeding issues and burnback if the contact tip is not properly dimensioned or cooled. These tips feature Lincoln's proprietary Copper Plus® technology, which increases the overall diameter of the tip. This design adds significant copper mass, acting as a superior heat sink that draws thermal energy away from the bore and the arc zone. By keeping the tip cooler, the structural integrity of the copper is maintained longer, and the risk of the aluminum wire fusing to the tip is drastically reduced.

Anti-Seize™ Thread Technology

One of the most common frustrations in high-amperage MIG welding is the seizing of contact tips within the diffuser, often requiring pliers or even damaging the gun to remove. The KP2744-035A features Anti-Seize™ threads with a specialized flattened profile. This innovative thread design reduces the surface area susceptible to bonding under high heat, ensuring that the tip remains easy to remove even after long welding sessions at 350 amps. This feature is particularly critical in industrial environments where downtime for torch maintenance must be kept to an absolute minimum.

Optimized for Magnum® PRO Systems

Engineered exclusively for the Magnum® PRO series of MIG guns, these contact tips ensure a perfect electrical connection and gas flow alignment. The .035-inch (0.9 mm) bore is precision-machined to accommodate the specific feeding characteristics of aluminum wire, providing stable arc initiation and consistent wire placement. Whether used in automated robotic cells or manual fabrication, these tips deliver the reliability professional welders demand. The 10-pack packaging ensures that your shop is well-stocked for continuous production runs.

Industrial Grade Performance

Rated for 350A, these contact tips are built to withstand the rigors of heavy fabrication. The combination of high-grade copper alloy and intelligent geometric design results in a consumable that outlasts standard tips, providing better value over time. By maintaining a cooler operating temperature, the electrical conductivity remains consistent, resulting in a smoother arc and higher quality aluminum welds.
