0458470882 - ESAB PSF 305 / 410W Straight MIG Nozzle 18mm (Pack of 2)

Precision Shielding for Professional Fabrication

The ESAB PSF 305/410W Straight Gas Nozzle (18mm) is a critical consumable designed to maintain the integrity and performance of your ESAB PSF series MIG torches. Engineered with precision, this nozzle features an 18mm bore diameter, which is ideal for applications requiring a broader envelope of shielding gas. The straight geometry of the nozzle is particularly beneficial for operators who prefer a consistent standoff distance or need to access joints where a tapered nozzle might restrict visibility or gas flow dynamics. By ensuring a laminar flow of shielding gas, this component significantly reduces the risk of atmospheric contamination, porosity, and oxidation in the weld pool.

Manufactured from high-grade copper alloy, the nozzle is built to withstand the intense thermal cycling inherent in industrial welding environments. Whether you are using the air-cooled PSF 305 or the water-cooled PSF 410W, this nozzle dissipates heat effectively, prolonging the life of the front-end consumables and the torch neck itself. The robust material composition also resists the adhesion of welding spatter, making it easier to clean and maintain during long shifts. Regular maintenance and timely replacement of the gas nozzle are essential for preventing short circuits and ensuring smooth wire feeding.

This product is supplied as a pack of two, providing welders and maintenance teams with immediate backup stock. Using genuine ESAB consumables guarantees that the threading and fitment match the original equipment specifications perfectly, preventing gas leaks at the diffuser connection. For heavy fabrication, structural steel, or manufacturing environments utilizing the PSF torch platform, this 18mm straight nozzle delivers the reliability and consistency required for code-quality welds.
