Miller Electric Millermatic 140

Miller Millermatic 140 electrical welder is an all-in-one MIG welder replacing the company’s Millermatic 135. Patent-pending Auto-Set automatically sets wire feed speed and voltage; the user only needs set the wire diameter and material thickness. This works with C25 gas and either .024 or .030 solid wire. The 115-volt unit can weld up to 3/16 inch in a single pass, the company says.
