KP2744-564T - Lincoln KP2744-564T Magnum PRO Copper Plus Contact Tip 5/64 Tapered (10-Pack)

Premium Performance for Industrial Fabrication

The Lincoln Electric KP2744-564T is a high-performance contact tip designed for the rigorous demands of industrial MIG welding. Part of the Magnum PRO consumable line, this tip is engineered to address the two most common failure modes in welding consumables: thermal degradation and thread seizure. By integrating Lincoln's proprietary Copper Plus technology, the tip features a larger diameter and mass compared to standard contact tips. This increased copper content significantly improves thermal conductivity, allowing heat to dissipate more rapidly from the arc zone. Consequently, the tip operates at lower temperatures, maintaining its structural integrity and electrical conductivity over longer periods of continuous welding.

This specific model is sized for 5/64-inch (2.0 mm) wire and features a tapered geometry. The tapered design is critical for applications requiring access to restricted joints or where improved visibility of the weld puddle is necessary. Despite its tapered profile, the tip retains sufficient mass to handle amperages up to 350A, making it suitable for heavy-duty fabrication tasks. The manufacturing precision ensures that the internal bore maintains consistent contact with the wire, promoting stable arc transfer and reducing micro-arcing that can lead to premature wear.

Maintenance and Efficiency

Operational efficiency is further enhanced by the Anti-Seize thread design. In high-heat environments, standard contact tips often expand and fuse to the gas diffuser, requiring pliers or vice grips for removal—often damaging the diffuser in the process. The KP2744-564T utilizes flattened thread profiles that reduce surface contact area within the threads, preventing the metallurgical bonding that causes seizing. This feature ensures that operators can perform tip changes quickly and by hand, minimizing downtime and reducing the consumption of gas diffusers. Supplied in a package of 10, these contact tips provide a cost-effective solution for maintaining the productivity of Magnum PRO MIG gun systems in high-volume production environments.
