The Lincoln Electric KP2744-364A-B100 is a bulk package of 100 Magnum® PRO Copper Plus® Contact Tips, specifically engineered for feeding 3/64-inch (1.2 mm) aluminum welding wire. These contact tips are a critical component in the Magnum® PRO expendables series, designed to address the unique challenges of aluminum GMAW (MIG) welding. Unlike standard tips, those designated with the 'A' suffix typically feature internal geometries optimized for the thermal expansion characteristics of aluminum wire, reducing friction and the likelihood of burn-back.
Manufactured using Lincoln's proprietary Copper Plus® alloy, these tips offer superior thermal conductivity compared to standard copper tips. This enhanced heat dissipation keeps the tip cooler during high-amperage operation (rated up to 350A), significantly extending the consumable's lifespan and maintaining consistent electrical conductivity. The larger mass and specialized alloy resist deformation and micro-arcing, ensuring stable arc performance even in demanding industrial environments.
These tips are compatible with Magnum® PRO semi-automatic and robotic MIG guns. The 350A rating makes them suitable for medium to heavy-duty fabrication tasks. By maintaining a cooler operating temperature, the Copper Plus® technology reduces the frequency of tip changes, thereby increasing overall arc-on time and productivity.
