0458471002 - ESAB PSF 250 Spatter Guard Insert

Technical Overview of the ESAB Spatter Protector (0458471002)

The ESAB Spatter Protector (Part Number: 0458 471 002) is a critical maintenance component engineered specifically for the ESAB PSF 250 series of MIG/MAG welding torches. This component serves as an internal shield within the nozzle assembly, designed to insulate the torch neck and contact tip holder from the intense heat and molten metal spatter generated during the welding process. By creating a barrier, it prevents spatter from bridging the electrical insulation or clogging the gas ports, which is essential for maintaining arc stability and shielding gas coverage.

Manufactured to ESAB's precise OEM specifications, this spatter protector ensures a perfect fit within the PSF 250 head assembly. Improper fitment of non-OEM parts can lead to gas turbulence and porosity in the weld; however, this genuine part maintains the laminar flow characteristics designed into the PSF torch series. It is constructed from high-temperature resistant materials capable of withstanding the thermal cycling inherent in industrial welding applications without deforming or degrading rapidly.

Regular inspection and replacement of the spatter protector are recommended as part of a preventative maintenance schedule. A degraded protector can lead to increased spatter adhesion on the gas nozzle and contact tip, eventually causing short circuits or restricted gas flow. This part is supplied individually and is a direct replacement for the original component installed in standard PSF 250 guns.
