0459990130 - ESAB PSF Series Conical Gas Nozzle 16mm

Precision Gas Coverage for PSF Series Guns

The ESAB 0459990130 Gas Nozzle is a premium MIG welding consumable designed to deliver consistent shielding gas flow and superior durability. Featuring a conical geometry and a 16mm (approx. 5/8") inner diameter, this nozzle is the standard choice for general purpose welding with ESAB PSF series guns, including the PSF 250, PSF 305, PSF 405, and PSF 505 models. The conical design improves operator visibility of the weld puddle and allows for better access into tighter joints compared to cylindrical nozzles.

Manufactured to ESAB's exacting standards, this nozzle is crafted from a robust copper alloy that offers excellent thermal conductivity. This helps dissipate heat rapidly, prolonging the life of the nozzle and reducing the adherence of molten spatter. A clean nozzle is critical for preventing turbulence in the shielding gas stream, which can lead to weld defects such as porosity. By maintaining the structural integrity of the nozzle opening, the ESAB 0459990130 ensures laminar gas flow for high-quality results.

This component also plays a vital role in the electrical insulation of the torch front-end, preventing accidental arcing against the workpiece. It is designed to seat securely on the torch neck, ensuring concentricity with the contact tip for uniform gas coverage. For professional welders demanding reliability and consistency, this genuine ESAB nozzle is the preferred choice for maintaining the performance of PSF MIG guns.
