KP2744-116AT5356 - Lincoln Magnum PRO Copper Plus Tip 1/16 Aluminum Tapered (10-Pack)

Technical Overview of Lincoln Electric KP2744-116AT5356

The Lincoln Electric KP2744-116AT5356 is a specialized contact tip from the Magnum PRO Copper Plus series, engineered specifically for industrial aluminum welding applications. This component is designed to accommodate 1/16-inch (1.6 mm) wire diameters and is optimized for use with 5356 aluminum alloys. The contact tip features a tapered geometry, which facilitates access to restricted joint configurations while maintaining structural integrity. It is rated for 350 amperes, making it suitable for medium-to-heavy duty fabrication cycles where thermal management is critical.

A defining characteristic of the Copper Plus line is the increased outer diameter relative to standard contact tips. This design modification results in a greater total mass of copper, which enhances the thermal conductivity and heat dissipation properties of the consumable. By effectively drawing heat away from the bore, the tip maintains a lower operating temperature, which is essential when welding aluminum due to the material's high thermal expansion rate. Cooler operation reduces the likelihood of micro-arcing inside the tip and prolongs the service life of the consumable.

The KP2744-116AT5356 is equipped with Lincoln Electric's proprietary anti-seize threading technology. In high-heat environments, standard threads can expand and fuse to the gas diffuser, necessitating the replacement of the entire front-end assembly. The anti-seize feature mitigates this risk, ensuring that the tip can be easily removed and replaced during routine maintenance. This specific SKU is tailored for 5356 aluminum wire, which is generally stiffer than 4043 series wire, requiring precise bore tolerances to ensure smooth feeding and consistent electrical transfer. The product is supplied in a package of 10 units, supporting inventory management for high-volume production environments utilizing Magnum PRO MIG gun platforms.
