KP2745-364AT - Lincoln Magnum PRO 3/64 Aluminum Contact Tip, Tapered, 550A (10-Pack)

Maximize Uptime with Magnum® PRO Copper Plus™ Contact Tips

Elevate your welding operations with the Lincoln Electric KP2745-364AT, a specialized contact tip designed for 3/64" aluminum wire applications. Welding aluminum presents distinct challenges compared to steel, primarily due to the softness of the wire and the high thermal conductivity required. Lincoln Electric has addressed these issues with the Copper Plus™ design, which provides a larger cross-sectional area than standard tips. This design enhancement allows for more efficient heat dissipation, keeping the tip temperature lower even at high amperages up to 550A. A cooler tip means less risk of the wire melting back to the tip (burn-back) and ensures consistent electrical transfer for a stable, smooth arc.

The KP2745-364AT is fully compatible with Lincoln's Magnum® PRO series of MIG guns, a platform known for durability and comfort. A critical innovation in this series is the patent-pending Anti-Seize™ thread technology. Traditional tips often seize in the diffuser due to thermal expansion and micro-arcing, leading to downtime and frustration. The Anti-Seize™ threads reduce the contact area within the thread interface, preventing the tip from locking up. This ensures that when a tip change is finally needed, it can be performed easily, getting the operator back to welding in seconds.

These tips feature a tapered profile, which is ideal for maintaining visibility and gas coverage in restricted spaces. The 3/64" bore is precision-machined to provide the optimal tolerance for aluminum wire feeding, reducing friction while maintaining excellent electrical contact. Whether you are working in automotive manufacturing, shipbuilding, or general aluminum fabrication, the KP2745-364AT offers the reliability and longevity professional welders demand. Each order includes a pack of 10 contact tips, providing excellent value and ensuring you have the necessary expendables on hand for continuous production.
