KP2742-1-62R-B25 - Lincoln Magnum PRO 350A MIG Nozzle, 5/8" ID, 1/8" Recess (25 Pack)

Industrial Grade MIG Consumables for High-Volume Fabrication

The Lincoln Electric KP2742-1-62R-B25 is a premium gas nozzle engineered for the Magnum PRO series of semi-automatic welding guns. Designed to meet the rigorous demands of industrial manufacturing, this nozzle is rated for 350 amps, making it suitable for a wide variety of medium to heavy-duty welding applications. The nozzle features a 5/8-inch (15.9 mm) inner diameter, providing a generous gas envelope that ensures excellent shielding coverage, even during weaving techniques or in less-than-ideal shop conditions. With a 1/8-inch (3.2 mm) recess, it offers a strategic balance between contact tip accessibility and protection.

Thermal management is a critical factor in consumable life, and the Magnum PRO line excels in this area. The KP2742-1-62R is constructed from a durable copper alloy that effectively dissipates heat from the welding arc. This rapid cooling capability helps prevent spatter from adhering tightly to the nozzle walls, simplifying cleaning and maintenance routines. Furthermore, the thread-on connection mechanism provides a distinct advantage over traditional slip-on designs. It ensures the nozzle remains concentric with the contact tip and diffuser, guaranteeing uniform gas flow and preventing the component from loosening due to thermal expansion and contraction.

Supplied in a bulk package of 25, the KP2742-1-62R-B25 is the ideal solution for fabrication shops and production lines seeking to optimize inventory management. By purchasing in bulk, facilities can reduce the administrative overhead of frequent reordering and ensure that welding stations are always stocked with essential consumables. This nozzle is specifically designed to pair with Magnum PRO 350A contact tips and diffusers, creating a cohesive front-end system that delivers consistent electrical conductivity and arc performance. Whether used for structural steel, automotive parts, or general machinery fabrication, this Lincoln Electric nozzle provides the reliability professionals expect.

The 1/8-inch recess is particularly advantageous for maintaining a consistent contact tip-to-work distance (CTWD) while shielding the tip from the direct intensity of the arc. This design feature helps reduce burn-back issues and extends the operational life of the contact tip, further driving down consumable costs. For operations prioritizing efficiency, quality, and equipment longevity, the Lincoln Electric KP2742-1-62R-B25 offers a superior solution for MIG welding front-end parts.
