KP4523-1-50F-B25 - Lincoln Magnum PRO Water-Cooled MIG Nozzle 1/2 Inch Flush 25-Pack

High-Performance Consumables for Water-Cooled Systems

The Lincoln Electric Magnum® PRO Water-Cooled Nozzle (KP4523-1-50F-B25) is a premium consumable component engineered specifically for Magnum® PRO Semi-Automatic Water-Cooled Welding Guns. This bulk package contains 25 flush-style nozzles, each featuring a 1/2-inch (12.7 mm) inner diameter. Designed to withstand the rigorous demands of high-amperage industrial welding, these nozzles are an essential inventory item for fabrication shops utilizing water-cooled MIG systems.

Optimized Geometry and Gas Flow

The 1/2-inch bore size is a versatile standard for general fabrication, providing a focused column of shielding gas that effectively protects the weld pool from atmospheric contamination without excessive gas waste. The "Flush" designation indicates that the nozzle's exit orifice sits flush with the end of the contact tip. This geometry is particularly beneficial for applications requiring a balance between gas coverage and the welder's ability to see the arc and puddle. Unlike recessed nozzles, which are often used for higher stick-out applications, or protruding nozzles used for tight access, the flush design offers a neutral stick-out ideal for short-circuit and spray transfer modes in flat and horizontal positions.

Durability in High-Heat Environments

Water-cooled MIG guns are typically employed in heavy-duty cycles where air-cooled equipment would overheat. Consequently, the consumables attached to these guns must be capable of enduring intense thermal stress. The Magnum PRO line is manufactured from high-grade copper alloys and materials that resist heat deformation and spatter adhesion. This ensures that the nozzle maintains its shape and conductivity over longer periods, reducing downtime associated with frequent consumable changes. The secure seating mechanism of the Magnum PRO series further ensures that the nozzle remains concentric to the contact tip, preventing uneven gas flow and potential weld defects.

Industrial Bulk Packaging

Supplied in a bulk pack of 25, the KP4523-1-50F-B25 SKU is tailored for high-volume manufacturing environments. Bulk packaging simplifies inventory management and reduces packaging waste, providing a cost-effective solution for facilities that run continuous welding operations. By maintaining a steady supply of these critical components, facility managers can ensure that production lines remain active and that weld quality remains consistent across shifts.
