KP4523-1-50F - Lincoln KP4523-1-50F Magnum PRO Water-Cooled Flush Nozzle 1/2 Inch

High-Performance Water-Cooled Consumables

The Lincoln Electric KP4523-1-50F is a premium gas nozzle engineered for the Magnum PRO series of semi-automatic water-cooled welding guns. Designed to meet the demands of heavy industrial fabrication, this nozzle is compatible with both 400A and 500A Magnum PRO water-cooled models. The component plays a critical role in directing shielding gas over the weld pool while protecting the contact tip and gas diffuser from the intense heat and spatter generated during high-amperage welding processes.

Advanced Material Engineering

Unlike standard copper nozzles, the KP4523-1-50F features a robust nickel plating. This specialized coating serves a dual purpose: it reflects radiant heat more effectively and, crucially, provides a surface that resists the adhesion of molten spatter. In high-volume production environments, this translates to less downtime spent scraping or cleaning nozzles and longer intervals between replacements. The underlying copper construction ensures excellent thermal conductivity, working in tandem with the gun's water-cooling system to maintain optimal operating temperatures even at high duty cycles.

Optimized Geometry

This specific nozzle features a "Flush" tip geometry with a 1/2-inch (12.7 mm) inner diameter (ID). The flush design places the nozzle exit parallel with the contact tip, offering a balanced performance profile. It provides better gas coverage than stick-out nozzles in drafty conditions while allowing for greater visibility and tighter access than recessed nozzles. The 1/2-inch bore is a versatile size, suitable for a wide range of wire diameters and shielding gas flow rates commonly used in structural and manufacturing applications.

System Compatibility

As a genuine Lincoln Electric part, this nozzle guarantees a perfect fit with Magnum PRO goosenecks. The secure threaded connection prevents gas leakage, ensuring shielding gas integrity and preventing porosity in the weld metal. It is an essential consumable for maintaining the reliability and efficiency of your water-cooled MIG welding setup.
