The Millermatic 140 mig welder with Auto-Set offers all the benefits of the standard Millermatic 140, but adds Auto-Set to eliminate the guesswork. Use Auto-Set when you want the speed, convenience and confidence of pre-set controls. Simply set the wire diameter, set the material thickness, and go! The Auto-Set control automatically sets your welder to the proper parameters. It is available when welding mild steel with solid wire and only works with .024 and .030 solid wires and C25 shielding gas (75% Argon, 25% CO2).
