KP2745-035A - Lincoln Electric KP2745-035A Magnum PRO Copper Plus Contact Tip for Aluminum (.035", 550A) - 10 Pack

Optimize Aluminum Welding with Magnum PRO Copper Plus Tips

Welding aluminum presents unique challenges, from wire softness to rapid heat accumulation. The Lincoln Electric KP2745-035A Copper Plus® Contact Tip is engineered to overcome these hurdles, providing a reliable solution for professional welders using Magnum® PRO MIG guns. This 10-pack of contact tips is designed specifically for .035" (0.9 mm) aluminum wire, offering a precise bore that accommodates the thermal expansion of aluminum without causing micro-arcing or drag.

Superior Heat Dissipation
The "Copper Plus" in the name refers to the specialized alloy and the physical design of the tip. With a larger mass than standard tips, the KP2745-035A effectively draws heat away from the bore and the arc zone. This is critical in aluminum welding, where excess heat at the tip can cause the wire to soften prematurely or burn back, leading to costly interruptions. By keeping the tip cooler, Lincoln Electric extends the consumable's lifespan and maintains a stable arc even at amperages as high as 550A.

Anti-Seize Technology
Frustrated by tips that get stuck in the diffuser? These tips feature Lincoln's patented Anti-Seize™ threads. The unique thread profile prevents the tip from bonding to the diffuser, even after long welding sessions at high heat. This ensures that when it is time to replace the tip, it unscrews smoothly, saving you time and frustration on the shop floor. Whether you are fabricating trailers, repairing automotive components, or working in marine construction, these tips deliver the consistency required for high-quality aluminum welds.
