The XTRWELD 404-1 is an OEM-quality gas diffuser designed for Tregaskiss Style 403 Series HD tips used in MIG welding applications. The diffuser directs shielding gas flow around the contact tip and into the weld zone, helping maintain arc stability and protecting the weld puddle from atmospheric contamination. Measuring 0.48 inches wide, 1.25 inches tall, and 0.48 inches deep, this compact component is a direct-fit replacement for technicians servicing MIG welding guns in production and fabrication environments. Each unit is marked with a part number for fast identification during changeovers.
This gas diffuser is built for use with Tregaskiss Tough Gun and Bernard BTB TGX welding guns. It is interchangeable with Tregaskiss traditional consumables and can serve as a full replacement for Tregaskiss Toughlock, AccuLock, and R Series consumables, though these series are not designed to be mixed within a single setup. Welding professionals in manufacturing, structural fabrication, and heavy equipment repair will find this a reliable consumable for high-duty-cycle gun assemblies.

Gas diffuser replacement is a standard consumable service task performed by welding technicians and MIG gun maintenance personnel. Always power down the welding power source and disconnect the gun from the feeder before servicing consumables. Use the appropriate spatter removal tool or contact tip removal tool to avoid damaging the gun neck threads. Inspect the gas ports on the diffuser for blockage before reinstalling the nozzle.
