OVERVIEW

High-Performance MIG Consumables: Lincoln KP2742-2-50S-B25

Maximize your welding efficiency with the Lincoln Electric KP2742-2-50S-B25 Magnum® PRO Gas Nozzle. Designed for professional welders who demand reliability, this 350A rated nozzle is a critical component for Magnum® PRO semi-automatic MIG guns. The nozzle plays a vital role in directing shielding gas to the weld pool and protecting the contact tip and diffuser from the intense heat of the arc. Lincoln Electric has engineered these nozzles to not only withstand this environment but also to assist in cooling the front end of the gun, prolonging the life of all front-end expendables.

The KP2742-2-50S-B25 features a slip-on design, which is a favorite among professionals for its ease of use. Unlike threaded nozzles that can become cross-threaded or fused due to spatter and heat, the slip-on style allows for quick removal for spatter cleaning or replacement. This model provides a 1/8 inch (3.2 mm) stickout and a 1/2 inch inner diameter, a configuration that offers versatile performance for general fabrication. The 1/2 inch bore provides ample gas coverage for standard fillet and butt welds, while the 1/8 inch stickout helps maintain a consistent electrical stickout for stable arc characteristics.

Supplied in a pack of 25, this product ensures your tool crib is well-stocked, minimizing production interruptions. Whether you are welding mild steel, stainless, or aluminum, using the correct nozzle geometry is essential for defect-free welds. The Magnum® PRO line represents Lincoln Electric's commitment to quality, offering consumables that stay cooler and last longer. Upgrade your welding operations with these durable, high-performance nozzles and experience the difference in your daily welding workflow.
