Platen Mounted Holders

TUFFALOY PM holders may be mounted directly to press-type welder platens, or they can be used as components of special weld fixturing. They come in two body sizes which match standard T-slot spacings, either of which can be furnished with a female taper to hold any tapered electrode or shank, or with threads for threaded electrodes or threaded adapters (straight thread style). The smaller holder is for use on RWMA Size 1 welders, which have the 3-1/2" spacing. The larger one is for the Size 2 and 3 welders, which have the 5- and 6-inch spacing.

Big, half-inch mounting bolts may be used to assure good conductivity. The holders may be used one-to-one or in multiples closely bunched. PM holders make special fixture building easy. They can be bolted to a fixture or back-up base as easily as to a platen. They are compact and have self-contained coolant systems.

Hose Connections: You may specify where you want the hose connectors in the hexagonal base. Select any two of the six possible locations and specify by using the symbols shown on the diagram (connect locations: A-B, or A-D, etc.). Position A-C is standard. (A-F and C-D are not possible.)

Stationary water tubes are available separately and should be selected based on the length of electrode being used.
