KP2745-116R - Lincoln Electric Magnum PRO Copper Plus Contact Tip 1/16" 550A (10-Pack)

High-Performance Industrial MIG Consumables

The Lincoln Electric KP2745-116R Copper Plus® Contact Tip is a premium consumable engineered for heavy-duty industrial welding environments. Designed specifically for the Magnum® PRO series of MIG guns, this contact tip addresses the common failure points of standard copper tips through advanced metallurgy and design. The "Copper Plus" designation refers to the increased diameter of the tip, which provides a larger thermal mass. This additional material acts as a superior heat sink, drawing thermal energy away from the bore and the arc zone. Combined with Copper Chrome Zirconium (CuCrZr) construction, the tip resists annealing and softening at high temperatures, maintaining its structural integrity and electrical conductivity far longer than standard copper tips.

For industrial operations where downtime equates to lost revenue, the KP2745-116R features Lincoln's patented Anti-Seize™ thread technology. The threads are engineered with a unique profile that reduces the contact area between the tip and the diffuser, preventing the two components from fusing together during high-amperage welding cycles (up to 550A). This ensures that tip changes are quick and tool-free, minimizing interruptions on the production line. The 1/16-inch (1.6 mm) bore is machined to tighter tolerances than standard tips, ensuring consistent wire placement and stable arc transfer, which is critical for achieving code-quality welds in structural and manufacturing applications.

These Extended Life contact tips are proven to feed an average of 20 lbs. more wire per tip compared to standard Magnum PRO counterparts, offering a tangible reduction in consumable costs over time. Sold in packs of 10, the KP2745-116R is the ideal choice for fabrication shops seeking to optimize the performance of their Lincoln Electric welding systems.
