The Broco large brass collet nut is knurled to assure the diver of a solid grasp and acme threads prevent binding from mud or other debris insuring quick reliable underwater welding and cutting rod insertion and retention. Interchangeable collets accommodate 1/4 in., 3/8 in. or 5/16 in. diameter underwater cutting rods, and use of available underwater welding collets allows the Broco BR-22 Underwater Cutting Torch to be used as an underwater welding electrode stinger.
