345P022271 - ESAB PSF Series Conical Gas Nozzle 16mm

Technical Overview of the ESAB 16mm Conical Nozzle

The ESAB Nozzle Nw 16mm (Part Number 345P022271 / 0345022271) is a standard replacement gas nozzle designed for the PSF series of MIG/MAG welding torches. Engineered to meet the rigorous demands of industrial welding, this nozzle features a 16mm bore diameter, which is the standard size for general-purpose fabrication, offering a reliable shield of gas around the weld pool.

With a length of approximately 75.5mm, this nozzle is sized to ensure the contact tip is properly recessed or flush depending on the specific torch setup, optimizing the stick-out and arc characteristics. The conical geometry allows the welder to access tighter joints and corners without compromising the shielding gas envelope. It is manufactured from high-grade copper alloy for excellent thermal conductivity and is finished with a nickel plating. This plating is critical for reflecting radiant heat and providing a smooth surface that resists the adhesion of molten spatter, thereby reducing maintenance frequency and downtime.

This component is directly compatible with ESAB PSF 305, PSF 405, and PSF 505 air-cooled and water-cooled torches. It serves as the primary gas directing shroud, ensuring laminar flow of shielding gas (Argon, CO2, or mixtures) to prevent porosity and oxidation in the weld metal.
