Automatically setting voltage and wire feed speed for your MIG welding application, the Millermatic® 140 mig welder with Auto-Set makes it easy to dial in the right welding parameters. 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 Miller 140 MIG Welder enables you to make smooth clean beads on thinner metal without burning through.

Typical Miller 140 MIG Welder Applications:

  • Garage, Auto Body
  • Farm, Ranch
  • Maintenance, Repair
  • Light Fabrication
  • Around the Home
  • Flux Cored (FCAW) (self-shielded wire)
  • MIG (GMAW)

Miller 140 MIG Welder Features:

NEW! Auto-Set is a breakthrough control that automatically sets your welder to the proper parameters. Auto-Set offers all-in-one MIG, minus the guesswork! Standard built-in solid-state contactor circuit makes wire electrically “cold” until trigger is pulled, making the unit safer, this makes it easier to position the MIG gun before starting to weld.

Miller 140 MIG Welder Manual Mode Gives you the flexibility to manually set the machine when welding aluminum, stainless steel or anytime you want to set your own parameters on mild steel.

Miller 140 MIG Welder Thermal Overload Protection Shuts down the unit and activates over-temperature light if airflow is blocked or duty cycle is exceeded. Automatically resets when fault is corrected and unit cools. Self-resetting motor protection circuit eliminates the need to find and replace fuses.

Miller 140 MIG Welder Smooth-Start This technology provides a smooth, spatter-free start. The best starting machine in the small MIG category! No more pop-gun starts or spatter to clean up.

Miller 140 MIG Welder Durable Cast Aluminum Drive System Incorporates dual groove quick-change drive roll and spring-loaded tension arm with calibrated tension knob, all designed to make setup easier and faster.

Miller 140 MIG Welder “Tip Saver” Short Circuit Protection Shuts down output when tip is shorted to the work. Extends contact tip life and protects internal components from damage. Trigger reset permits quick reset at torch rather than unit. See how it works.

Miller 140 MIG Welder Easy Access to Output Studs Easy access to output studs provides convenient polarity changeover when changing from solid or flux cored wires.Provides convenient polarity changeover when switching from solid or flux cored wires. NEW! direct connect with optional Spoolmate 100 Spoolgun. Semiautomatic constant voltage wire welding package is capable of welding 24 gauge up to 3/16 in (0.8 – 4.8 mm) mild steel. Uses 4 or 8 in (102 or 203 mm) MIG welding wire  spools and can be set up to weld with wire sizes .024–.030 in (0.6–0.8 mm) mild/stainless steel and .030 –.035 in (0.8 – 0.9 mm) flux cored wire.
