TUFFALOY high-pressure tips have flat bottoms. Elimination of the usual
tapered-sockets and tip-jamming. Assembled tip and holder heights are
always the same, as contrasted to tapered tips which can be forced into
the sockets varying distances.
TUFFALOY high pressure tips can be used in the two holder styles shown: PM
holders for mounting on the platens of press-type welders, and straight
holders for spot welder arm mounting. The tips are held to the holders by
a threaded coupling. Copper tungsten faced tips are available for high
