KP2744-564-B100 - Lincoln Electric Magnum PRO Copper Plus Contact Tip 5/64 in (2.0 mm) - 100 Pack

High-Performance Contact Tips for Industrial Welding

The Lincoln Electric KP2744-564-B100 is a premium consumable package designed to support high-volume welding operations utilizing Magnum® PRO MIG guns. This product consists of a 100-pack of Copper Plus® contact tips, specifically engineered for 5/64 inch (2.0 mm) welding wire. These tips are rated for 350A applications, making them a robust choice for structural fabrication, heavy equipment manufacturing, and other industrial sectors where arc stability and thermal management are critical. The internal geometry and material composition are optimized to handle the electrical and thermal stresses associated with higher amperage welding.

Copper Plus® Technology

A defining feature of the KP2744-564-B100 is the Copper Plus® technology. Standard contact tips often suffer from rapid degradation due to excessive heat buildup at the point of contact. Lincoln Electric addresses this by increasing the overall diameter of the tip, thereby increasing the copper mass. This additional mass acts as a more effective heat sink, dispersing thermal energy away from the bore and keeping the tip cooler during extended arc-on times. The result is a contact tip that maintains its structural integrity and electrical conductivity for longer periods, reducing the frequency of changeovers.

Anti-Seize™ Thread Design

Maintenance efficiency is further enhanced by the Anti-Seize™ threading integrated into these contact tips. In high-heat environments, standard threads can expand and fuse to the gas diffuser, leading to seized parts that are difficult to remove without damaging the gun assembly. The Magnum® PRO tips feature a specialized thread profile that mitigates this risk, ensuring that tips can be easily unscrewed and replaced even after being subjected to extreme thermal cycling. This feature protects the longevity of the gas diffuser and reduces unplanned downtime.

Compatibility and Specifications

These contact tips are exclusively compatible with the Magnum® PRO series of MIG guns and expendables. They are precision-machined to accommodate 5/64 inch (2.0 mm) wire, ensuring a consistent electrical transfer that is vital for maintaining a stable arc and reducing micro-arcing within the tip. The 100-pack configuration (B100) provides a cost-effective solution for facilities with high consumption rates, ensuring that operators have immediate access to replacement parts.
