KP4523-1-50S-B25 - Lincoln Electric Magnum PRO Water-Cooled Nozzle 1/2" ID 1/8" Stickout (25 Pack)

High-Performance Consumables for Industrial Fabrication

The Lincoln Electric KP4523-1-50S-B25 is a premium gas nozzle designed exclusively for the Magnum PRO series of semi-automatic water-cooled welding guns. Engineered to meet the rigorous demands of heavy industry, this nozzle features a 1/2-inch (12.7 mm) inner diameter and a 1/8-inch (3.2 mm) stickout. This specific geometry is optimized for a wide range of welding applications where a balance between gas coverage and joint accessibility is required. The 1/8-inch stickout allows the contact tip to protrude slightly, providing the welder with better visibility of the arc and the weld puddle, which is critical for precision work in complex joints.

As part of the Magnum PRO expendables line, these nozzles are built to deliver superior performance and extended service life. The water-cooled design implies compatibility with high-amperage welding procedures where heat management is paramount. By effectively channeling shielding gas and withstanding the intense thermal cycles of continuous welding, the KP4523-1-50S-B25 ensures consistent weld quality and reduces the frequency of consumable changes. This translates to higher productivity and lower operational costs over time.

This product is supplied as a bulk pack of 25 units. This packaging configuration is ideal for large manufacturing facilities, shipyards, and fabrication shops that consume welding parts at a high rate. Maintaining a healthy stock of essential consumables like gas nozzles prevents unexpected downtime and ensures that production lines keep moving efficiently. The nozzles are manufactured to tight tolerances, ensuring a secure fit on the diffuser and preventing issues such as gas leakage or air entrainment that can lead to porosity.

Whether you are welding structural steel, heavy machinery, or automotive components, the reliability of your consumables directly impacts the quality of your output. Lincoln Electric's commitment to quality ensures that every nozzle in this pack performs consistently, helping professional welders achieve defect-free welds shift after shift.
