Charles 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] Two years earlier, Nikolay Slavyanov presented the same idea of transferring metal across an arc, but to cast metal in a mold.[2]
