Miller Electric is an American arc welding and cutting equipment manufacturing company based in Appleton, Wisconsin.

Miller Electric, has grown from a one-man operation selling products in northeastern Wisconsin to what is today one of the world's largest manufacturers of arc welding and cutting equipment.

[citation needed] ITW had much in common with Miller Electric in terms of business philosophy, and in 1992 it was ranked as one of the 100 "Most Admired American Corporations" by Fortune magazine.
