0700200080 - ESAB MXL 340 Replacement Gas Diffuser White

Precision Gas Control for MXL 340 Torches

Maximize the performance of your ESAB MXL 340 MIG gun with the genuine ESAB White Gas Diffuser, part number 0700200080. For professional welders, the gas diffuser is more than just a connector; it is the final stage of gas management before the shielding gas reaches the arc. This component is critically engineered to convert the turbulent flow of gas from the liner into a laminar, columnar flow that effectively shields the molten weld pool from atmospheric contamination.

The "White" designation of this diffuser corresponds to the specific thermal and mechanical requirements of the MXL 340 series. It features precision-machined threads and gas ports that align perfectly with the gun's geometry. This ensures that the contact tip is centered and electrically conductive, while simultaneously directing the shielding gas—whether CO2 or an Argon mix—evenly across the work area. Inconsistent gas coverage is a primary cause of porosity and spatter; replacing worn diffusers with this OEM part restores the gun's original performance parameters.

Durability is a key feature of the ESAB 0700200080. It is manufactured from high-grade materials capable of resisting the intense radiant heat generated during the welding process. Furthermore, the surface finish helps resist the adhesion of spatter, making it easier to clean and extending the service life of the component. When paired with a compatible nozzle and contact tip, this diffuser completes a high-efficiency front-end assembly that supports stable arc transfer and clean bead profiles.

Technical specifications matter in high-amperage applications. Using ill-fitting or generic diffusers can lead to gas leakage inside the nozzle or poor electrical conductivity to the tip. This ESAB diffuser guarantees the correct standoff and gas distribution pattern intended by the manufacturer, ensuring that your welding parameters translate accurately to the workpiece. Keep your MXL 340 running at peak efficiency with this essential consumable.
