KP2744-364AT - Lincoln Magnum PRO 3/64 Aluminum Contact Tip Tapered (10-Pack)

Lincoln Electric KP2744-364AT: The Aluminum Specialist

Upgrade your welding operations with the Lincoln Electric KP2744-364AT Copper Plus Contact Tip, specifically engineered for 3/64" (1.2 mm) aluminum wire applications. Designed to fit the industry-leading Magnum® PRO series of MIG guns, these contact tips represent a leap forward in consumable longevity and performance. Standard contact tips often struggle with the high thermal conductivity and expansion rates of aluminum wire, leading to premature failure and erratic arcs. The KP2744-364AT utilizes Copper Plus® technology, which increases the overall mass and copper content of the tip. This design acts as a superior heat sink, drawing thermal energy away from the bore and keeping the tip temperature stable, even at amperages up to 350A.

Built for the Industrial Environment

Efficiency in the shop is driven by minimizing interruptions. The KP2744-364AT features Lincoln's patented Anti-Seize™ thread technology. In heavy-duty welding cycles, thermal cycling can cause standard threads to lock into the diffuser, requiring pliers or vice grips to remove. The Anti-Seize threads prevent this fusion, allowing for hand-tightening and easy removal, thereby streamlining maintenance and tip changeovers. This durability makes them a cost-effective choice for high-volume manufacturing.

Optimized Geometry

The physical shape of the contact tip plays a crucial role in weld quality. This model features a tapered profile, which serves two primary functions. First, it reduces the tip's footprint, allowing for better access into V-grooves and corners. Second, it optimizes the flow of shielding gas around the arc, ensuring the sensitive aluminum weld pool is fully protected from atmospheric contamination. Whether you are fabricating trailers, signage, or automotive components, the KP2744-364AT delivers the consistency and reliability professional welders demand. Each package contains 10 contact tips.
