KP4523-1-75F-B25 - Lincoln Magnum PRO Water-Cooled Flush Nozzle 3/4-Inch (25-Pack)

High-Performance Consumables for Industrial Fabrication

The Lincoln Electric KP4523-1-75F-B25 is a bulk package of premium gas nozzles designed specifically for the Magnum® PRO line of water-cooled semi-automatic welding guns. In high-production industrial environments, the integrity of the gas shielding system is paramount to maintaining weld quality and reducing rework. These nozzles are engineered to withstand the intense thermal cycling associated with high-amperage water-cooled applications, ensuring consistent performance over extended duty cycles.

This specific nozzle features a Flush tip geometry. In the Magnum PRO system, a flush nozzle positions the contact tip end even with the nozzle exit. This configuration is widely favored in manufacturing as it offers a balanced compromise between the gas shielding efficiency of a recessed tip and the joint accessibility of a stickout tip. It allows operators to maintain a proper contact-tip-to-work distance (CTWD) while still providing excellent visibility of the weld puddle, which is critical for precision tracking in semi-automatic processes.

The nozzle boasts a large 3/4-inch (19.1 mm) inner diameter (ID). This wide bore is essential for high-deposition welding where large weld pools require a broader envelope of shielding gas to prevent atmospheric contamination and porosity. The larger opening also assists in reducing the rate of spatter bridging, a common issue in high-heat applications that can disrupt gas flow. Constructed from high-grade copper alloy, these nozzles effectively dissipate radiant heat, prolonging the life of the front-end consumables.

Supplied in a bulk pack of 25, the KP4523-1-75F-B25 is intended for high-volume fabrication shops, robotic cells, and heavy equipment manufacturing facilities where consumable turnover is frequent. By purchasing in bulk, procurement departments can ensure continuous uptime and reduce the administrative overhead of frequent reordering. These nozzles integrate seamlessly with Lincoln's Magnum PRO diffuser systems, ensuring a tight, leak-proof fit that maximizes gas efficiency.
