KP24A-50-B25 - Lincoln Electric KP24A-50-B25 Magnum Adjustable Slip-On Nozzle 1/2" (25-Pack)

Lincoln Electric KP24A-50-B25 Gas Nozzle Overview

The Lincoln Electric KP24A-50-B25 is a high-performance gas nozzle designed for industrial MIG welding applications. Engineered to fit the widely used Magnum 300 and Magnum 400 series semiautomatic guns, this nozzle is a staple for fabrication shops requiring reliability and precision. The nozzle features a standard 0.50-inch (12.7 mm) inner diameter, which provides excellent shielding gas coverage for a variety of welding modes, including short-circuit and spray transfer. Its construction is robust, capable of enduring the thermal stresses associated with high-amperage welding while maintaining its structural integrity.

A defining characteristic of the KP24A-50-B25 is its adjustable slip-on design. Unlike fixed threaded nozzles, this slip-on variant allows the operator to slide the nozzle up or down the gun tube. This functionality is critical for adjusting the contact tip recess or stick-out, enabling the welder to adapt to specific joint geometries or welding procedure specifications (WPS). The friction fit is engineered to hold the nozzle securely in place during operation while still allowing for removal without the need for specialized tools, facilitating quick maintenance and spatter removal.

This product is supplied in a bulk package of 25 units, making it an ideal procurement choice for large-scale manufacturing environments and heavy equipment repair facilities. By purchasing in bulk, facilities can ensure consistent machine uptime and standardize their consumable inventory. The nozzle is compatible with wire sizes ranging from .025 inches to 5/64 inches, covering the vast majority of standard MIG wire applications. Whether working with mild steel, stainless steel, or flux-cored wires requiring gas shielding, the KP24A-50-B25 delivers consistent performance and durability.

Lincoln Electric's commitment to quality ensures that each nozzle in the pack meets strict dimensional tolerances. This consistency guarantees that gas flow remains laminar and effective, reducing the risk of porosity and weld defects caused by turbulent shielding gas. For maintenance and repair operations (MRO) and production welding alike, the KP24A-50-B25 represents a standard of quality in MIG gun consumables.
