KP23-62-B25 - Lincoln Electric Fixed Recess Gas Nozzle, 5/8" Bore, 25-Pack

Lincoln Electric KP23-62-B25 Gas Nozzle Overview

The Lincoln Electric KP23-62-B25 is a premium-grade gas nozzle designed to meet the rigorous demands of industrial MIG welding. Engineered specifically for the Magnum® series of semiautomatic guns, including the Magnum 250LX, 300, and 400 models, this consumable is an essential component for maintaining high-quality weld integrity. The nozzle features a 0.62-inch (15.7 mm) inner diameter, commonly referred to as a 5/8-inch bore. This dimension is critical for applications operating between 250 and 400 amps, as it allows for a sufficient volume of shielding gas to flow over the weld pool, effectively protecting it from atmospheric contamination such as oxygen and nitrogen which can cause porosity.

A defining characteristic of the KP23-62-B25 is its "Fixed Recess" design. In this configuration, the contact tip is positioned slightly deeper inside the nozzle body. This recess serves multiple technical purposes: it helps prevent the contact tip from shorting out against the workpiece during tight maneuvers, reduces the accumulation of spatter directly on the tip face, and ensures a consistent wire stick-out length. Consistent stick-out is vital for maintaining stable voltage and amperage parameters during the welding process. This nozzle is compatible with a broad range of wire sizes, from light gauge .025" wire up to heavier 5/64" diameters, making it a versatile choice for fabrication shops handling diverse projects.

Supplied in a bulk package of 25, this product is tailored for high-volume production environments where minimizing downtime is a priority. By keeping a stock of these durable copper-alloy nozzles, operators can quickly replace worn or clogged components and return to welding immediately. The standard shape and robust construction ensure longevity even under the thermal stress of continuous high-amperage welding cycles.
