KP2744-364AT5356 - Lincoln Magnum PRO Contact Tip 3/64 Aluminum 5356 Tapered (10-Pack)

Maximize Uptime with Long-Lasting Magnum PRO Tips

Upgrade your welding arsenal with the Lincoln Electric KP2744-364AT5356, a high-performance contact tip designed to take the frustration out of aluminum MIG welding. If you are welding with 3/64" (1.2 mm) 5356 aluminum wire, you know that feedability and arc stability are paramount. Standard tips often fail prematurely due to the intense heat and the abrasive nature of aluminum oxide. The Magnum® PRO Copper Plus® contact tips are the solution, delivering a significant upgrade in durability and performance over standard copper tips.

The secret lies in the Copper Plus® alloy. This material is engineered to withstand higher temperatures without softening, which prevents the wire from fusing to the tip—a common annoyance known as burnback. The tip's design features a larger mass which acts as a heat sink, pulling thermal energy away from the bore. This ensures that the electrical contact point remains consistent throughout the life of the tip. For the welder, this means a stable arc, less spatter, and fewer trips to the tool crib to grab a replacement. This specific model is rated for applications up to 350 amps, covering a vast range of fabrication jobs.

Visibility is key to a good weld, and the tapered design of the KP2744-364AT5356 offers a clear line of sight to the puddle. Whether you are welding in a flat position or maneuvering around a pipe, the tapered nose helps you get the nozzle right where it needs to be. Furthermore, this tip is specifically bored for 5356 wire. Since 5356 is stiffer than 4043, it requires a specific tolerance to feed smoothly without wandering. Lincoln Electric has precision-machined these tips to ensure optimal wire-to-tip contact for superior conductivity.

Sold in a value-packed bag of 10, these contact tips are a smart investment for any professional welder. They are designed to fit Magnum PRO guns, featuring anti-seize threads that ensure the tip comes out as easily as it went in, even after a long shift of hot work. Don't let inferior consumables hold back your productivity; switch to Magnum PRO Copper Plus and experience the difference in your aluminum welding projects.
