0466905002 - ESAB PSF Conical Gas Nozzle for Fume Extraction Torches

Genuine ESAB Replacement for PSF Fume Extraction Systems

The ESAB Extractor Nozzle (0466905002) is a critical consumable component designed specifically for the ESAB PSF series of fume extraction MIG torches. In high-production welding environments where source capture of fumes is mandatory, the integrity of the torch front-end consumables is paramount. This conical gas nozzle is engineered to precise tolerances to ensure it fits seamlessly with the PSF 405 K, PSF 410 W, and related fume extraction gun models.

Manufactured from a high-conductivity copper alloy, this nozzle excels in thermal management. Fume extraction torches often operate at higher temperatures due to the added bulk of the vacuum shroud and the enclosed nature of the front end; therefore, efficient heat dissipation is essential to prevent premature failure of the nozzle and the contact tip within. The conical shape is the industry standard for general fabrication, offering an excellent balance between gas coverage and visibility of the weld pool.

Furthermore, the geometry of the 0466905002 nozzle plays a subtle but important role in the aerodynamics of the fume capture process. By maintaining the correct standoff and alignment relative to the outer vacuum shroud, it ensures that the shielding gas envelope is not disrupted by the extraction vacuum, preventing porosity while maximizing fume removal efficiency. Regular replacement of this nozzle is recommended to maintain compliance with safety standards and to ensure defect-free welds.

Technical Compatibility

This nozzle is verified for use with the Centrovac and PSF fume extraction lines. Users should consult their specific torch breakdown to confirm compatibility, but it is widely recognized as the standard conical replacement for the heavy-duty air and water-cooled fume guns in the ESAB lineup.
