KP2744-564T-B100 - Lincoln Electric Magnum PRO 350A Tapered Contact Tip 5/64 (100-Pack)

High-Performance Contact Tips for Industrial Welding

The Lincoln Electric KP2744-564T-B100 is a bulk package of 100 premium contact tips designed for the Magnum PRO series of MIG guns. Engineered for high-amperage applications, these tips are rated for 350A and are specifically sized for 5/64 inch (2.0 mm) welding wire. The "T" in the part number designates a tapered geometry, which is critical for welders requiring better visibility of the arc and weld puddle, as well as improved access into tight corners or narrow groove weldments.

At the core of this product is Lincoln Electric's proprietary Copper Plus® technology. Unlike standard copper tips that can soften and deform under intense heat, Copper Plus® alloy retains its hardness and conductivity at elevated temperatures. This results in a contact tip that dissipates heat more efficiently, reducing the likelihood of wire burn-back and micro-arcing inside the tip bore. For industrial operations, this translates to significantly longer consumable life and fewer interruptions for maintenance.

The Magnum PRO contact tip design also features a unique coarse thread with a flattened profile. This engineering choice serves two purposes: it prevents the tip from seizing to the gas diffuser—a common issue in high-heat welding—and it maximizes the surface area for electrical contact, ensuring stable current transfer to the wire. This 100-pack configuration (B100) is ideal for high-volume fabrication shops and robotic welding cells where consistent throughput and inventory management are priorities.

By utilizing genuine Lincoln Electric consumables, operators ensure the integrity of their welding system. The KP2744-564T-B100 provides the reliability needed for structural steel, heavy equipment manufacturing, and other demanding sectors where 350A continuous welding is routine.
