Tuffaloy Resistance Welding Products – Caps and Shanks FOR SALE from Weld Systems Integrators

Tuffaloy caps and shanks (Tuffcap electrodes) consist of two pieces: a shank and a replaceable cap. These two-part electrodes can offer major economies, because when the nose geometry is worn out, only the cap needs to be replaced. Furthermore, it costs far less than a standard one-piece electrode. (A Tuffcap shank will normally outlast twenty caps.) Also, electrode inventory can be kept small because all nose designs will fit the same size shank.

Tuffaloy offers two kinds of Tuffcap electrodes. One uses a male cap that fits into the shank. The other has a female cap that fits over the shank.

Male Caps and Female Caps

Male Caps and Female Caps are available in the widest range of sizes, alloys, and styles. They are made in both Class 1 and Class 2 alloy, and in sizes to fit- shanks sized 4 through 7 RW. Male caps are more effectively cooled than female caps.

ALL CAPS are made with the same nose designs in conformance with RWMA standards.

To avoid mushrooming and brassing problems associated with standard designs, these caps have a self-dressing weld face ring that acts as a control zone. The Super Nose caps are available in TUFFALOY’s new “Z” material, that eliminates electrode sticking problems common when welding galvanized and aluminized materials. Both male and female designs are offered, designed to fit shanks with 5 RW taper.
