The XTRWELD 404-13 is a gas diffuser with set screw designed as an OEM-quality replacement consumable for Tregaskiss Style 403 Series HD Tips. It measures 0.73 inches in width and 1.75 inches in height, making it a direct-fit component in MIG welding gun assemblies. The part is marked with its part number for fast identification during consumable swaps. Welding technicians and fabricators install this diffuser to maintain consistent gas flow coverage at the weld zone, ensuring proper shielding gas distribution across the contact tip area.
This diffuser is compatible with Tregaskiss Tough Gun and Bernard BTB TGX welding guns. It is designed as a Tregaskiss-style traditional consumable, meaning it can be used as a full replacement for Tregaskiss Toughlock, AccuLock, and R series consumables. Note that these series are not intended to be mixed within a single setup — use as a complete consumable replacement only. Typical applications include production MIG welding in industrial, fabrication, and manufacturing environments where high-duty-cycle gun performance is required.
Designed for use with Tregaskiss Tough Gun and Bernard BTB TGX welding guns. Fits Tregaskiss Style 403 Series HD Tips. Can serve as a full replacement for Tregaskiss Toughlock, AccuLock, and R series consumables; these series should not be mixed within the same setup.
Installation is performed by a qualified welding technician or machine operator. Power down and de-energize the welding system before replacing any consumable components. Use appropriate hand tools to secure the set screw to the manufacturer-recommended fit — do not overtighten. Inspect the gun neck and liner condition before installing a new diffuser to confirm proper seating and gas flow path integrity.
