KP2744-035AT - Lincoln Electric KP2744-035AT Magnum PRO Copper Plus Contact Tip, .035 Aluminum, Tapered (10-Pack)

Technical Specifications and Compatibility

The Lincoln Electric KP2744-035AT is a high-performance contact tip designed for use with Magnum® PRO AL series MIG guns, including the Magnum® PRO 250LX, 250LX GT, and AL G225A models. This specific SKU is optimized for feeding .035-inch (0.9 mm) aluminum welding wire. The contact tip features a tapered geometry, which reduces the front-end profile of the gun, allowing for better access into tight corners and providing the welder with an unobstructed view of the arc and puddle.

Copper Plus® and Anti-Seize™ Features

Lincoln's Copper Plus® formulation utilizes a larger physical diameter and a specialized copper alloy to improve thermal conductivity. By effectively drawing heat away from the bore, the tip maintains structural integrity longer than standard tips, which is particularly important when welding aluminum due to the wire's tendency to expand and drag when overheated. Additionally, the Anti-Seize™ threads feature a flattened thread profile that reduces surface area contact with the diffuser, preventing thermal lock-up and ensuring the tip can be easily removed even after high-amperage cycling.

Performance Ratings

These tips are an essential consumable for operators using Lincoln Electric push-pull or spool gun systems for aluminum fabrication. The precise bore tolerance ensures consistent electrical contact (micro-arcing reduction) and stable arc transfer, resulting in cleaner welds with less burn-back.
