KP4523-1-75R-B25 - Lincoln Magnum PRO Water-Cooled Nozzle 3/4 ID 1/8 Recess (25-Pack)

Premium Lincoln Electric Magnum PRO Water-Cooled Nozzles

Maximize the efficiency and quality of your industrial welding operations with the Lincoln Electric KP4523-1-75R-B25 Magnum PRO Water-Cooled Nozzle. Designed specifically for the rigorous demands of high-amperage MIG welding, these nozzles are an essential component for fabricators using Magnum PRO Semi-Automatic Water-Cooled Welding Guns. This bulk package contains 25 premium-quality nozzles, ensuring your shop remains stocked and ready for continuous production without unnecessary downtime.

The KP4523-1-75R model features a substantial 3/4-inch (19.1 mm) inner diameter (ID). This large bore size is critical for maintaining excellent shielding gas coverage over the weld pool, particularly when welding at higher currents where the puddle is larger and more fluid. Proper gas coverage prevents porosity and ensures a clean, sound weld, reducing the need for costly rework. Additionally, the nozzle is engineered with a 1/8-inch (3.2 mm) recess. This recessed design places the contact tip slightly back inside the nozzle, offering enhanced protection against radiant heat and reducing the likelihood of spatter bridging, which can interrupt gas flow.

Durability is at the core of the Magnum PRO series. These water-cooled nozzles are manufactured from high-grade copper alloys capable of withstanding the intense thermal cycles associated with water-cooled applications. The threaded connection ensures a tight, secure fit to the diffuser, promoting efficient heat transfer away from the front end of the gun. This thermal management helps extend the life of both the nozzle and the contact tip, ultimately lowering your total cost of ownership for consumables.

Whether you are working in heavy equipment manufacturing, structural steel fabrication, or automated welding environments, the Lincoln Electric KP4523-1-75R-B25 provides the consistency and reliability professional welders demand. Trust Josef Gas to supply authentic Lincoln Electric consumables that keep your arc stable and your production line moving.
