998893 - ESAB MT-250SG MIG Gun Nozzle #8 (1/2")

Genuine ESAB Precision for Aluminum and Steel Welding

The ESAB 998893 Nozzle Assembly #8 is a critical consumable designed specifically for the ESAB MT-250SG Spool Gun. In industrial welding environments, particularly when working with aluminum using a spool gun, the integrity of the shielding gas envelope is paramount. This genuine OEM nozzle features a #8 orifice, translating to a 1/2-inch bore, which is the industry standard for a wide range of wire diameters and welding applications. By maintaining a consistent and laminar flow of shielding gas—whether Argon or an Argon/CO2 mix—this nozzle effectively protects the molten weld pool from atmospheric contamination, reducing the risk of porosity and oxidation.

Constructed from high-grade copper alloy, the 998893 nozzle is engineered to withstand the intense thermal cycling and reflected heat typical of MIG welding. Its robust design resists the adhesion of spatter, although regular use of anti-spatter compounds is recommended to extend its service life further. Using genuine ESAB parts ensures that the threading and fitment are exact, preventing gas leaks at the diffuser connection that could otherwise compromise weld quality. For fabrication shops and maintenance departments relying on the MT-250SG for reliable wire feeding and mobility, stocking genuine ESAB nozzles is a best practice for maintaining equipment uptime and weld consistency.

This nozzle is packaged individually, ensuring it arrives in factory-perfect condition, ready for immediate deployment. It is an essential component for any welder operating the MT-250SG system, providing the durability and performance expected from the ESAB brand.
