KP2744-116A - Lincoln Electric KP2744-116A Magnum PRO Copper Plus Contact Tip for Aluminum Wire, 1/16 in - 10 Pack

Industrial Grade Aluminum Welding Consumables

The Lincoln Electric KP2744-116A is a specialized contact tip designed for the rigorous demands of industrial aluminum MIG welding. Part of the Magnum® PRO consumable line, this tip is engineered with Lincoln's proprietary Copper Plus® technology. Unlike standard contact tips, Copper Plus® tips feature a larger outer diameter which significantly increases the total copper mass. This design enhancement allows for superior thermal conductivity, effectively dispersing the intense heat generated during the welding arc. For maintenance, repair, and operations (MRO) professionals, this translates to longer consumable life and reduced frequency of tip changes, optimizing production uptime.

This specific SKU is tailored for 1/16-inch (1.6 mm) aluminum wire. Aluminum wire presents unique challenges in feeding and electrical transfer due to its softness and high thermal expansion rate. The KP2744-116A is manufactured with precise internal tolerances to accommodate the expansion of aluminum wire without causing binding or micro-arcing inside the bore. Furthermore, the tip is equipped with Anti-Seize™ Threading. This flattened thread profile reduces the surface area contact between the tip and the diffuser threads, preventing the common industrial issue of tips melting or seizing in the gun during high-heat applications. This feature ensures that tips can be removed and replaced easily, even after long duty cycles.

Compatible exclusively with Magnum® PRO MIG guns, these contact tips are an essential stock item for fabrication shops working with heavy-gauge aluminum. The 10-pack packaging ensures that welding stations remain supplied, minimizing inventory management overhead. By utilizing the KP2744-116A, facilities can ensure consistent electrical contact and arc stability, which are critical for meeting code-quality aluminum welds in manufacturing and structural applications.
