KP2745-035A-B100 - Lincoln Magnum PRO Copper Plus Contact Tip .035 Aluminum (100-Pack)

High-Performance Consumables for Industrial Aluminum Welding

The Lincoln Electric KP2745-035A-B100 is a bulk package of 100 Magnum PRO Contact Tips, specifically engineered for welding with 0.035-inch (0.9 mm) aluminum wire. In high-throughput industrial environments, consumable longevity and wire feeding reliability are critical to maintaining production schedules. These contact tips feature Lincoln's proprietary Copper Plus technology, which utilizes a specialized copper alloy and a design with greater mass. This construction significantly improves heat dissipation, keeping the tip cooler during extended arc-on times and reducing the rate of bore wear and keyholing.

Aluminum wire presents unique challenges in MIG welding due to its high rate of thermal expansion and softness. Standard steel tips often cause aluminum wire to bind or seize as it heats up within the tip. The "A" designation in this SKU indicates that these tips are manufactured with a slightly larger internal clearance to accommodate this expansion, ensuring smooth wire delivery and stable arc characteristics. By preventing micro-arcing inside the tip and reducing burn-back frequency, these consumables help minimize unscheduled downtime for tip changes.

Designed for use with Magnum PRO 350 and 550 amperage class MIG guns, these tips are an essential stock item for fabrication shops specializing in aluminum structures, automotive components, or marine vessels. The bulk packaging of 100 units offers excellent inventory control and cost efficiency for large-scale operations.
