KP2744-364AT-B100 - Lincoln Magnum PRO 3/64 Aluminum Tapered Contact Tip (100-Pack)

Superior Performance for Aluminum MIG Welding

Welding aluminum demands precision, and your contact tip is the final transfer point for your welding current. The Lincoln Electric Magnum® PRO Copper Plus® Contact Tip (KP2744-364AT-B100) is built to handle the heat and frustration often associated with aluminum MIG work. Designed with a specific tapered shape, these tips give you the visibility you need to see the puddle clearly, even in tight corners or complex joints. The 3/64 inch (1.2 mm) size is perfectly matched to your aluminum wire, ensuring smooth feeding and a stable arc.

The Copper Plus Difference

Heat is the enemy of contact tip life. Lincoln's Copper Plus® technology puts more metal in the tip, creating a larger heat sink that draws thermal energy away from the bore. This means the tip stays cooler, lasts longer, and resists the "keyholing" effect that ruins accuracy over time. For aluminum welders, this thermal efficiency is crucial because it helps prevent the wire from softening too early or burning back into the tip, saving you from constant interruptions to clear birdnests or replace fused parts.

Built for the Professional

This 100-pack is ideal for busy shops that can't afford to run out of consumables in the middle of a job. Rated for up to 350 amps, these tips are robust enough for heavy-duty fabrication while maintaining the finesse required for precision aluminum beads. Whether you are building trailers, boat hulls, or automotive components, upgrading to Magnum® PRO Copper Plus® tips ensures that your equipment works as hard as you do. The tapered design not only helps with sight lines but also assists in directing shielding gas flow precisely where it's needed, reducing porosity and oxidation in your finished welds.
