KP2745-052-B100 - Lincoln Magnum PRO .052 Contact Tips, 550A Copper Plus (100-Pack)

High-Performance Consumables for Industrial Fabrication

The Lincoln Electric KP2745-052-B100 Magnum® PRO Copper Plus® Contact Tip is engineered to address the most common pain points in high-amperage MIG welding: thermal degradation and component seizure. Designed for industrial environments utilizing .052-inch (1.3 mm) wire, this contact tip represents a significant upgrade in consumable technology. The proprietary Copper Plus® formulation increases the physical mass and copper content of the tip, allowing for superior thermal conductivity. By dissipating heat more efficiently than standard tips, the Copper Plus® design maintains structural integrity longer, ensuring consistent electrical transfer and arc stability even during extended weld cycles at up to 550 amps.

Operational efficiency is further enhanced by Lincoln Electric's Anti-Seize™ threading technology. In heavy-duty applications, thermal expansion and micro-arcing can often cause standard tips to fuse to the gas diffuser, leading to costly downtime and potential damage to the MIG gun neck. The KP2745-052-B100 features a specialized thread profile that resists this fusing process, ensuring that tip changes are quick, tool-free, and non-destructive. This attention to mechanical interface design translates directly to higher arc-on time and lower maintenance overhead.

This product is supplied in a bulk package of 100 units, specifically tailored for high-volume manufacturing and fabrication shops where inventory management is critical. By standardizing on the Magnum® PRO platform, facilities can leverage a single consumable line across various amperage ranges and gun configurations, simplifying stock requirements. The KP2745-052-B100 is compatible with the entire Magnum® PRO series of MIG guns, offering a versatile solution for structural steel, heavy equipment manufacturing, and general industrial fabrication.
