TREGASKISS 404-18 retaining head

The TREGASKISS 404-18 is a slip-on retaining head from the TOUGH LOCK series designed for MIG welding guns. It fits Bernard BTB, Clean Air fume extraction and Tregaskiss robotic MIG guns for standard duty applications.

0.023 to 0.125 in wire capacity

This brass retaining head accommodates wire diameters from 0.023 in up to 0.125 in. It handles the full standard range but cannot accept wires thicker than the 0.125 in maximum specified for the diffuser.

Slip-on connection interface

The slip-on connection installs without threads for quick diffuser changes. It is limited to TOUGH LOCK compatible guns and will not secure to threaded or other proprietary mounting systems.

Questions about this item

Will the 404-18 retaining head fit the Bernard BTB MIG gun I already use?

Yes — the 404-18 is listed as compatible with Bernard BTB MIG guns, Clean Air fume-extraction MIG guns and Tregaskiss robotic MIG guns.

How do I confirm the slip-on dual-taper connection is seated correctly after installation?

Push the retaining head onto the diffuser until it stops; the dual-taper design centres itself and a firm, wobble-free fit shows it is fully engaged.

Does the package include a gas diffuser or just the retaining head, and what wire range does it cover?

The box contains the 404-18 retaining head only; it accepts wire from .023 in to .125 in, and a matching TOUGH LOCK diffuser must be purchased separately.
