KP4523-1-62R-B25 - Lincoln Magnum PRO Water-Cooled Nozzle 5/8 ID 1/8 Recess (25-Pack)

Reliable Shielding for Water-Cooled MIG Guns

Welders know that the quality of the arc is only as good as the consumables at the front end of the torch. The Lincoln Electric KP4523-1-62R-B25 is a bulk package of 25 high-quality gas nozzles designed specifically for Magnum® PRO Water-Cooled MIG guns. When you are pushing high amps and laying down serious beads, you need a nozzle that can take the heat and keep the gas flowing smoothly. This 25-pack ensures you have plenty of stock on hand, so you never have to stop a job because you ran out of fresh nozzles.

Precision Engineering for the Professional

The geometry of a nozzle dictates how well it performs in tight spots and how effectively it shields the puddle. This model features a 5/8-inch inner diameter, a versatile size that balances gas coverage with access to the joint. It is ideal for spray transfer and pulsed MIG applications where consistent shielding is non-negotiable. The 1/8-inch recess is a favorite among professionals because it keeps the contact tip tucked away safely. This slight recess reduces the chance of the tip shorting out against the workpiece if you get too close, and it also helps keep the tip cooler by shielding it from the direct radiant heat of the arc.

Built for the Magnum PRO Advantage

Lincoln's Magnum PRO line is synonymous with durability and performance. These nozzles are crafted to match that reputation, featuring heavy walls that resist deformation when hot. The secure threaded connection prevents the nozzle from wobbling or falling off, even during aggressive manipulation of the gun. Whether you are welding structural steel, heavy machinery, or pressure vessels, these water-cooled nozzles deliver the consistency you need. The bulk packaging is perfect for tool cribs and welding stations, ensuring that every operator has immediate access to fresh consumables to keep their welds clean and porosity-free.
