KP2743-1-62R-B25 - Lincoln Magnum PRO 550A MIG Nozzle, 5/8" Bore, 1/8" Recess, Thread-on (25 Pack)

High-Performance Lincoln Electric Magnum PRO Nozzles

The Lincoln Electric KP2743-1-62R-B25 is a premium bulk package of Magnum PRO Gas Nozzles, specifically engineered to meet the rigorous demands of industrial semi-automatic welding. Designed for professionals who require consistency and durability, these nozzles are rated for 550 amps, making them suitable for high-heat applications where standard consumables might fail. The package contains 25 individual nozzles, providing a cost-effective solution for high-volume fabrication shops looking to maintain inventory levels and reduce administrative reordering time. By investing in genuine Lincoln Electric consumables, you ensure that your equipment operates at peak efficiency, minimizing downtime associated with inferior parts.

These nozzles feature a thread-on design, which is a significant upgrade over traditional slip-on models. The threaded connection ensures that the nozzle remains concentric to the contact tip, providing uniform gas coverage around the weld pool. Additionally, the tight mechanical fit facilitates better heat transfer from the nozzle to the gun tube, helping to keep the front-end consumables cooler during extended arc-on times. This thermal management is crucial for preventing spatter adhesion and extending the life of the nozzle itself. The 5/8-inch inner diameter is a versatile size, appropriate for a wide range of wire diameters and shielding gas flow rates, ensuring that your welding operations remain versatile and adaptable.

The KP2743-1-62R-B25 nozzles are designed with a 1/8-inch recess. This specific geometry places the contact tip slightly back inside the nozzle, offering a layer of protection against short-circuiting against the workpiece and reducing the accumulation of spatter on the tip face. This recess is ideal for general fabrication where the operator needs a balance between tip protection and puddle visibility. Whether you are welding structural steel, heavy machinery, or automotive components, these Magnum PRO nozzles deliver the reliability synonymous with the Lincoln Electric brand. This 25-pack ensures your team has the necessary supplies on hand to keep production moving smoothly without interruption.
