C. L. Coffin.html



C.L. Coffin of Detroit was awarded U.S. Patent 428,459  for an arc welding process using a metal electrode. This was the first time that metal melted from the electrode carried across the arc to deposit filler metal in the joint to make a weld.¹ About the same time, N.G. Slavianoff, a Russian, presented the same idea of transferring metal across an arc, but to cast metal in a mold.²
