KP2744-030-B100 - Lincoln Magnum PRO .030 Contact Tips 350A (100-Pack)

High-Performance Consumables for Industrial Fabrication

The Lincoln Electric KP2744-030-B100 is a bulk package of premium contact tips designed for the Magnum PRO series of MIG welding guns. Engineered for high-amperage industrial environments, these tips are rated for 350A applications and are precision-bored for .030-inch (0.8 mm) welding wire. This specific SKU is supplied in a quantity of 100, making it an ideal procurement choice for large-scale manufacturing facilities, heavy fabrication shops, and MRO departments seeking to optimize inventory levels and reduce procurement frequency.

Copper Plus Technology

At the core of the KP2744-030-B100's performance is Lincoln Electric's proprietary Copper Plus technology. These contact tips are manufactured with a larger outer diameter than comparable standard tips. This increase in physical mass allows for a higher volume of copper content. The thermodynamic benefit is significant: the added copper acts as a superior heat sink, effectively dispersing thermal energy generated during the welding arc. By keeping the tip temperature lower during operation, the structural integrity of the copper is maintained for longer periods, directly translating to extended consumable life and reduced changeover frequency.

Anti-Seize Engineering

Operational efficiency is further enhanced by the inclusion of Anti-Seize threading. In high-heat welding applications, standard contact tips can often expand and fuse to the gas diffuser, leading to seized components that require forceful removal or result in damaged torch parts. The Magnum PRO tips feature a specialized thread design that mitigates this risk, ensuring that tips can be removed and replaced smoothly even after prolonged exposure to high welding currents. This feature protects the gas diffuser and reduces the total cost of ownership for the MIG gun assembly.

Magnum PRO Compatibility

These tips are an integral part of the Magnum PRO expendables platform. They are designed to work seamlessly with Lincoln Electric's range of Magnum PRO MIG guns, ensuring optimal electrical conductivity and arc stability. The consistent bore diameter ensures reliable wire feeding, reducing the likelihood of burn-backs and micro-arcing within the tip.
