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

High-Performance Consumables for Industrial Fabrication

The Lincoln Electric KP4523-1-62R-B25 Magnum® PRO Water-Cooled Nozzle is a premium consumable designed to meet the rigorous demands of heavy industrial welding. Supplied in a convenient bulk pack of 25, this product is tailored for high-volume fabrication shops that utilize Lincoln's advanced Magnum PRO water-cooled semi-automatic MIG guns. By maintaining a ready supply of these essential components, facility managers can minimize downtime associated with consumable changeovers and ensure continuous production flow.

Optimized Dimensions for Quality Welds

This specific nozzle features a 5/8-inch (15.9 mm) inner diameter (ID), which is widely regarded as the standard bore size for a broad range of welding amperages. It provides a generous envelope of shielding gas, ensuring that the weld pool remains protected from atmospheric contamination even during higher-deposition transfer modes. Additionally, the nozzle is engineered with a 1/8-inch (3.2 mm) contact tip recess. This recess places the contact tip slightly back inside the nozzle, offering a critical layer of protection against spatter buildup that can bridge the gap between the tip and the nozzle wall. This design helps prevent electrical shorts and extends the lifespan of the contact tip itself.

Durability and Compatibility

Manufactured from high-grade copper alloy, the KP4523-1-62R nozzle is built to withstand the intense thermal cycles inherent in water-cooled welding applications. Water-cooled guns are typically employed for high-amperage work where air-cooled equipment would overheat; therefore, the consumables attached to them must be equally robust. The threaded design ensures a tight, concentric fit onto the gas diffuser, promoting laminar gas flow and reducing turbulence. This nozzle is fully compatible with the Magnum PRO series of water-cooled guns, ensuring seamless integration into your existing Lincoln Electric equipment ecosystem.
