KP3375-1 - Lincoln Magnum PRO Water-Cooled MIG Nozzle #10 (5/8 in)

High-Performance Cooling for Industrial Fabrication

The Lincoln Electric KP3375-1 Water Cooled Nozzle is a premium consumable component engineered for the rigorous demands of high-amperage MIG welding. Part of the renowned Magnum PRO series, this nozzle is specifically designed to integrate seamlessly with Lincoln's water-cooled MIG gun platforms. By utilizing a water-cooled architecture, this nozzle effectively manages the intense thermal loads generated during prolonged welding arcs, significantly reducing the risk of overheating and extending the service life of both the nozzle and the contact tip.

With a #10 cup size and a 5/8 inch (15.9 mm) bore diameter, the KP3375-1 provides a balanced shielding gas envelope suitable for a wide range of wire diameters and transfer modes, including spray transfer and pulsed MIG. The precise internal geometry ensures laminar gas flow, minimizing turbulence and preventing atmospheric contamination of the weld pool. This is particularly critical in applications involving aluminum or stainless steel, where porosity and oxidation must be strictly controlled.

Constructed from high-grade copper alloy, the nozzle offers excellent thermal conductivity and resistance to spatter adhesion. Its robust design withstands the mechanical stresses of industrial environments, making it a reliable choice for heavy fabrication, shipbuilding, and automotive manufacturing. When paired with Magnum PRO water-cooled torches, the KP3375-1 ensures consistent performance, reduced downtime for consumable changes, and superior weld quality.
