TUFFALOY REFACTORY METAL-FACED TIPS

TUFFALOY Copper-tungsten and copper-molybdenum faced tips withstand greater heat and pressure, at the expense of some conductivity. Besides being used for spot welding high resistance base metals, they are useful in achieving "heat balance" when welding dissimilar metals. (The higher resistance electrode is used against the lower resistance, or thinner member, to help contain the heat generated.) They have the same diameters and tapers as the standard straight tips in this catalog. Bodies are of Class 2 alloy. Lengths and nose configurations other than those shown can be ordered.
