KP2745-116AT-B100 - Lincoln Electric Magnum PRO Copper Plus Contact Tip 550A Tapered for Aluminum 1/16in (100-Pack)

Maximize Uptime with Magnum PRO Copper Plus Tips

Keep your welding operations running smoothly with the Lincoln Electric KP2745-116AT-B100 contact tips. This 100-pack of high-amperage tips is designed for professional welders who demand reliability and longevity from their consumables. Specifically engineered for use with 1/16 inch (1.6 mm) aluminum wire, these tips solve the common feeding issues associated with aluminum MIG welding. The bore is precision-machined to allow for the natural expansion of aluminum as it heats, preventing the wire from dragging or seizing inside the tip—a common cause of bird-nesting and downtime.

The "Copper Plus®" designation refers to a specialized copper alloy that significantly outperforms standard C12200 copper in durability and heat resistance. In high-amperage applications (up to 550A), standard tips can quickly wear out or keyhole, leading to an unstable arc and poor weld quality. These Magnum PRO tips maintain their shape and conductivity longer, meaning you spend less time changing parts and more time welding. The tapered design is another welder-centric feature, reducing the profile of the gun's front end to help you get into corners and tight angles without sacrificing gas coverage.

Designed for the Magnum PRO series of MIG guns, these tips utilize a robust thread design that prevents them from fusing to the gas diffuser, a common frustration in high-heat applications. Whether you are working in a shipyard, a trailer manufacturing plant, or a custom fabrication shop, this bulk pack ensures you have the inventory needed to maintain continuous production. Investing in application-specific consumables like the KP2745-116AT translates directly to better arc starts, fewer feed problems, and higher quality aluminum welds.

Why Choose Copper Plus?

Lincoln Electric's focus on consumable life means fewer interruptions. By choosing the B100 bulk pack, shops can secure a lower cost per tip while ensuring their welding stations are fully stocked for heavy aluminum projects. Experience the difference that a purpose-built aluminum contact tip can make in your daily fabrication workflow.
