KP2745-116A-B100 - Lincoln Magnum PRO Copper Plus Aluminum Contact Tip 1/16 in (100 Pack)

Industrial Grade Lincoln Electric KP2745-116A-B100 Contact Tips

The Lincoln Electric KP2745-116A-B100 is a premium bulk package of 100 Copper Plus® contact tips, engineered specifically for high-amperage aluminum welding applications. Designed to integrate seamlessly with the Magnum® PRO series of MIG guns, these contact tips represent a significant advancement in consumable technology for industrial fabrication. The 1/16 inch (1.6 mm) diameter is precision-machined to accommodate the specific feed characteristics of aluminum wire, ensuring consistent electrical contact and smooth wire feeding even under the thermal stress of 550A output.

At the core of this product is Lincoln's proprietary Copper Plus® technology. Unlike standard copper tips which can soften and degrade rapidly under high heat, the Copper Plus alloy is formulated to retain hardness and conductivity at elevated temperatures. This is critical in aluminum welding, where the wire itself is softer and more prone to micro-arcing inside the tip if the bore wears out prematurely. By maintaining the integrity of the contact point for longer periods, these tips reduce the frequency of line stoppages for maintenance, thereby increasing overall shop throughput and efficiency.

The physical design of the KP2745-116A-B100 also contributes to its superior performance. The tips feature a larger mass than standard consumables, acting as a more effective heat sink. This draws thermal energy away from the arc zone and the wire, preventing the common issue of burn-back where the wire fuses to the tip. Furthermore, the Magnum PRO system utilizes a patent-pending anti-seize thread design. The flattened thread profile increases the surface area contact between the tip and the gas diffuser, which not only improves heat transfer but also prevents the tip from seizing in the gun, a frequent frustration in high-heat industrial welding environments.

This 100-pack configuration is ideal for large-scale manufacturing facilities, shipyards, and heavy fabrication shops where aluminum welding is a primary process. By investing in high-quality consumables like the KP2745-116A-B100, procurement managers can ensure their welding teams have the reliable components necessary to maintain high duty cycles and superior weld quality. The tips are compatible with Magnum PRO semi-automatic and robotic torches, making them a versatile addition to any inventory managing Lincoln Electric equipment.
