KP24A-62-B25 - Lincoln Electric KP24A-62-B25 Adjustable Slip-On Gas Nozzle 5/8" ID (25-Pack)

Lincoln Electric KP24A-62-B25 Gas Nozzle Overview

The Lincoln Electric KP24A-62-B25 is a premium-quality gas nozzle designed to meet the rigorous demands of industrial MIG welding environments. Supplied in a cost-effective bulk package of 25, this consumable is a critical component for maintaining the efficiency and consistency of your welding production line. Specifically engineered for use with Lincoln Electric's widely respected Magnum® 300 and Magnum® 400 series semiautomatic MIG guns, this nozzle ensures seamless compatibility, proper electrical isolation, and reliable operation under high-amperage conditions.

Featuring a 0.62-inch (15.7 mm) inner diameter—commonly referred to in the industry as a 5/8" nozzle—it provides a balanced and laminar flow of shielding gas. This dimension is the industry standard for general fabrication, offering a wide umbrella of gas coverage to protect the molten weld pool from atmospheric contamination such as nitrogen and oxygen, which can cause porosity. The nozzle utilizes a slip-on connection mechanism, distinct from threaded designs, which facilitates rapid removal and replacement. This feature significantly reduces downtime during routine maintenance or when clearing spatter buildup. Furthermore, the adjustable nature of the slip-on fit enables welders to easily slide the nozzle along the gun tube to modify the position relative to the contact tip. This allows for precise control over contact tip stick-out (CTSO), accommodating various joint configurations and welding procedure specifications.

Constructed from high-grade copper alloy, the KP24A-62-B25 is built to withstand the intense heat associated with the Magnum 400 series, which is rated up to 400 amps. The material's thermal conductivity helps dissipate heat effectively, prolonging the life of the nozzle even in continuous, high-duty-cycle welding applications. This nozzle supports a versatile range of wire diameters, from fine .025" gauge up to heavy 5/64" wire, making it a flexible choice for shops that handle various material thicknesses and wire types. By choosing genuine Lincoln Electric consumables, operators ensure that their equipment functions as intended, maintaining arc stability and weld quality.

For industrial facilities, shipyards, and fabrication shops, the 25-pack configuration (B25) offers excellent inventory management convenience. Keeping a steady supply of these critical consumables on hand prevents unexpected work stoppages and simplifies procurement processes. Whether you are welding mild steel, stainless steel, or aluminum using the Magnum platform, the KP24A-62-B25 delivers the consistency and performance professional welders expect from Lincoln Electric products.
