WebW. H. Preece investigated the fusing (melting) current of a wire. He developed Equation 1 for fusing current (Note 2): I = a*d 3/2 Eq. 1 where I is the fusing current, d is the diameter of the wire in inches, and a is a constant that depends on the material. He determined that a = 10,244 for copper. A little algebra transforms this equation to: WebNot all metals will work as a Fused Glass Metal Inclusions.
