TREGASKISS 404-18-25 Retaining Head

The TREGASKISS 404-18-25 is a slip-on retaining head built for MIG welding guns in the TOUGH LOCK series. It fits Bernard air-cooled and T-Gun water-cooled models as well as Tregaskiss robotic air-cooled and water-cooled guns. The brass construction supports standard-duty welding across a wire range of .023 to .125 inches.

Replaces worn slip-on retaining heads

Swap this head when the existing diffuser wears out or when changing to a different wire diameter within the supported range. The dual taper design maintains consistent gas coverage so the upgrade is worth it whenever contact-tip life drops or shielding becomes uneven.

Brass body handles standard-duty cycles

Under sustained MIG welding the brass diffuser dissipates heat steadily without the deformation seen in lighter alloys. It keeps gas flow stable during long passes on air-cooled or water-cooled guns, reducing the need for frequent tip changes.

Questions about this item

Will this retaining head fit my Bernard air-cooled MIG gun?

Yes, the 404-18-25 slip-on retaining head is made for Bernard air-cooled and T-Gun water-cooled MIG guns, plus Tregaskiss robotic air-cooled and water-cooled models.

How do I install the slip-on retaining head without damaging the diffuser?

Slide the retaining head straight onto the 404-18-25 gas diffuser until it seats fully; the common error is twisting it, which can strip the brass threads.

When should I replace this brass retaining head during heavy MIG welding?

Replace it when the slip-on fit becomes loose, the dual-taper seat shows wear, or wire feeding becomes erratic at the .023 to .125 in diameter range.
