KP2744-564 - Lincoln Magnum PRO 350A Contact Tip 5/64 Copper Plus (10-Pack)

Premium Performance with Lincoln Copper Plus Technology

The Lincoln Electric KP2744-564 is a high-performance contact tip designed for the rigorous demands of industrial MIG welding. Part of the Magnum® PRO consumable line, this tip features Lincoln's proprietary Copper Plus® technology. Unlike standard contact tips, Copper Plus tips are engineered with a larger diameter and increased copper mass. This design enhancement significantly improves the thermal conductivity of the consumable, allowing it to disperse arc heat more rapidly. By keeping the tip cooler during operation, the structural integrity of the copper is maintained for longer periods, resisting the softening and keyholing that often lead to premature failure in high-amperage applications.

Rated for 350 Amps and sized for 5/64-inch (2.0 mm) wire, this contact tip is built to handle heavy-duty fabrication tasks. One of the most common issues in high-heat welding environments is the seizing of the contact tip within the gas diffuser, which can turn a simple consumable change into a costly repair involving damaged threads or replaced diffusers. To combat this, the KP2744-564 utilizes Anti-Seize™ thread technology. The threads are designed with a unique flattened profile that reduces the surface area prone to fusion, ensuring that the tip can be easily unscrewed even after long welding cycles at high heat.

Reliability in the arc zone is critical for maintaining weld quality and throughput. The precision machining of the KP2744-564 ensures consistent electrical contact with the welding wire, promoting a stable arc and reducing micro-arcing inside the tip. This attention to tolerance and material composition makes the Magnum PRO Copper Plus line a superior choice for automated and semi-automatic welding cells where downtime must be minimized. Each package contains 10 contact tips, providing a convenient supply for ongoing production needs.

Key Technical Benefits

• Thermal Management: Increased copper mass dissipates heat faster, extending tip life.
• Maintenance Efficiency: Anti-Seize threads prevent the tip from fusing to the diffuser.
• Compatibility: Designed exclusively for the Magnum PRO series of MIG guns.
