On the list of best inventions ever, right behind the MIG welder, you'll find the invention of the basic welding cart. Miller decided to combine the two on the Miller Millermatic 140 MIG Welder with Auto-Set and Cart.

The Miller Millermatic 140 Auto-Set and Economy Cart features a breakthrough control that automatically sets your welder to the proper parameters. Auto-Set offers all-in-one MIG minus the guesswork; simply set the wire diameter, set the material thickness and start welding. It's that easy! Prefer to set the parameters on your own? 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. Thermal Overload Protection shuts down the unit and activates over-temperature light if airflow is blocked or duty cycle is exceeded. Once the unit cools and the fault is corrected, the unit automatically resets its self. If that isn't enough, patented Tip Saver Short Circuit Protection shuts down output when tip is shorted to the work. This extends contact tip life and protects internal components from damage. A trigger reset allows you to quickly reset at the torch rather than the unit.

Miller's advanced Smooth-Start technology provides a smooth, spatter-free start. They even make the claim that this is the best starting machine in the small MIG category. No more pop-gun starts or spatter to clean up. The 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. Standard built-in, solid-state contractor circuit makes wire electrically "cold" until trigger is pulled. This makes the unit safer and torch easier to position before starting to weld.
