KP2745-116AT5356 - Lincoln Magnum PRO Copper Plus Contact Tip 1/16 Aluminum 550A (10-Pack)

High-Performance Thermal Management for Aluminum Welding

The Lincoln Electric KP2745-116AT5356 Copper Plus Contact Tip is a specialized consumable engineered for the rigorous demands of high-amperage aluminum welding. Part of the Magnum PRO series, this contact tip utilizes Lincoln's proprietary Copper Plus technology. By increasing the overall diameter of the tip, a greater mass of copper is available to absorb and dissipate the intense heat generated during the welding arc. This thermal efficiency is critical when welding aluminum, as it helps maintain consistent conductivity and prevents the premature failure often associated with overheating.

Designed specifically for use with 1/16-inch (1.6 mm) 5356 aluminum wire, this tip features a tapered geometry. The tapered profile serves a dual purpose: it facilitates access to tight joints and improves the welder's visibility of the puddle, which is essential for precision aluminum work. The tip is rated for 550A applications, making it suitable for heavy-duty industrial fabrication. It is compatible with Magnum PRO AL push-pull guns and pistol push-pull configurations, ensuring seamless integration into existing high-performance setups.

A key mechanical feature of the KP2745-116AT5356 is its anti-seize threading. Aluminum welding environments can lead to micro-arcing and heat buildup that typically causes standard tips to fuse to the diffuser. The anti-seize design mitigates this risk, ensuring that maintenance and tip changes remain quick and non-destructive to the gun assembly. This product is supplied in a pack of 10, providing a reliable inventory for continuous production environments.
