KP4523-1-50R-B25 - Lincoln Magnum PRO Water-Cooled Nozzle 1/2 Inch ID 1/8 Recess (25-Pack)

Reliable Shielding for Water-Cooled MIG Welding

When you are pushing high amps through a water-cooled gun, you need a nozzle that can take the heat. The Lincoln Electric Magnum PRO Water-Cooled Nozzle (KP4523-1-50R-B25) is built to deliver superior durability and performance in the toughest welding conditions. Designed as a direct replacement for Magnum PRO water-cooled series guns, these nozzles help you maintain a stable arc and clean welds by ensuring consistent gas coverage right where you need it.

The 1/2-inch bore strikes a perfect balance between gas flow and accessibility, making it a versatile choice for many joint configurations. The 1/8-inch tip recess is a favorite among professional welders because it helps keep the contact tip cleaner for longer. By recessing the tip, you reduce the accumulation of spatter on the tip face and minimize the risk of arcing out on the nozzle itself during tight corner work. This design also helps focus the shielding gas column, providing robust coverage even in drafty shop environments.

Built for the Pro

Lincoln Electric's Magnum PRO line is synonymous with longevity. These nozzles are manufactured from high-quality copper alloy materials that resist deformation and spatter adhesion. Whether you are welding structural steel, heavy machinery, or pressure vessels, these nozzles provide the thermal conductivity needed to keep your front-end cool.

Value and Convenience

This item comes as a bulk pack of 25 nozzles. For busy welders and shop managers, this means fewer orders to place and less downtime waiting for parts. Keep your tool crib stocked and your arcs lit with genuine Lincoln Electric consumables that are designed to perform as hard as you do.
