KP2744-030A - Lincoln Magnum PRO Aluminum Contact Tip .030 350A (10-Pack)

High-Performance Contact Tips for Aluminum Welding

The Lincoln Electric KP2744-030A is a premium contact tip designed specifically for use with the Magnum® PRO series of MIG welding guns. Part of the Copper Plus® line, these tips are engineered to withstand the rigors of industrial welding environments while providing superior electrical conductivity and heat dissipation. This specific model is tailored for .030-inch (0.8 mm) aluminum wire, a material known for its unique feeding challenges and thermal expansion properties.

Standard contact tips often struggle with aluminum wire because the material expands significantly as it heats up during the welding process. If a standard steel-wire tip is used, the aluminum can seize inside the bore, causing burnback, bird-nesting, and erratic arc performance. The KP2744-030A addresses this with a specialized geometry and bore tolerance that accommodates the expansion of aluminum, ensuring smooth wire feeding and consistent electrical contact throughout the weld.

The Copper Plus® alloy used in these tips offers a distinct advantage over standard copper tips. It resists softening at high temperatures, which helps maintain the integrity of the tip's bore over longer periods. This durability translates to fewer tip changes, reduced downtime, and lower overall consumable costs. Rated for 350 amps, these tips are suitable for a wide range of fabrication tasks, from automotive repair to light industrial manufacturing.

Each package contains 10 contact tips, ensuring you have an adequate supply for your welding operations. By using genuine Lincoln Electric consumables, you ensure optimal compatibility with your Magnum PRO equipment and maintain the high-quality standards expected in professional welding applications.
