TIG Torch Current Fitting, Torch End For WP-18 Water-Cooled Cables. 3/8" x 24 Left-hand current nipple, for WP-18, type 350 amp water-cooled TIG power cables.  Use with FAL-500, or FAL-525 hose ferrule.

Note:

There is an art to installing these fittings.  Great care should be taken to get the proper cable crimp to insure ample water flow and good electrical connection.  Additionally, you need to make sure that the cable does not bunch-up inside the hose which will cause a water flow restriction.
