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

Maximize Performance with Lincoln Magnum PRO Copper Plus Tips

For professional welders tackling aluminum projects, the Lincoln Electric KP2745-116A-B100 Copper Plus® contact tip is the ultimate solution for stability and longevity. Aluminum MIG welding presents unique challenges, primarily due to the softness of the wire and its high rate of thermal expansion. Standard contact tips often fail because they cannot dissipate heat fast enough, leading to the wire expanding inside the tip, causing friction, erratic feeding, and eventually burn-back. Lincoln Electric has addressed this directly with the Copper Plus alloy, designed to withstand the intense heat of 550A welding while maintaining a smooth, consistent bore for 1/16 inch (1.6 mm) aluminum wire.

The difference is in the details. The KP2745-116A-B100 features the Magnum® PRO signature anti-seize thread design. If you have ever struggled to remove a fused contact tip after a long day of welding, you will appreciate this engineering. The coarse, flattened threads are designed to prevent the tip from melting into the diffuser, ensuring that when it is finally time to swap consumables, the process is quick and tool-friendly. Additionally, the increased mass of the tip helps pull heat away from the front end of the gun, keeping your consumables cooler and your arc more stable.

This bulk pack of 100 tips ensures you are stocked for the long haul. In high-production environments, the time spent walking to the tool crib or changing out inferior tips adds up to significant lost revenue. By using Copper Plus tips, you get more arc-on time per tip. The alloy resists keyholing—the wearing of the tip bore into an oval shape—which is essential for accurate aiming and consistent electrical transfer. When the current transfer is consistent, your weld bead profile remains uniform, reducing the need for rework and grinding.

Whether you are welding thick aluminum plate in a shipyard or fabricating custom aluminum components in a shop, the reliability of your contact tip dictates the quality of your day. The KP2745-116A-B100 is built to handle the demands of pulsed MIG and high-amperage spray transfer modes often used with aluminum. Upgrade your Magnum PRO setup with these specialized tips and experience the difference that premium consumables make in arc control and wire feed smoothness.
