You could check miller's web site (miller welds) for the details and specifications - but bacically they are the same machine with the 140 and/or 180 with A/S having a computer system that will automatically select the volts/amps and wire speed for you based on the thickness of the material you select. It's designed for the home hobby person who hasn't been through training and the A/S setting will help a novice person get the machine up, running properly and build confidence. Some people are a little intimidated by welding and all the variables you need to figure out to weld properly (wire size, wire type, volts, amps, wire speed and the differences for various metals)
On the 140 manual version you have to look those settings up yourself on a Mig setting chart/guide/wheel - and then manually enter those settings via the knobs on the face of the manual machine. The Miller version of the MIG guide is about 3 dollars at your local welding supply store.
The A/S version of the 140 and 180 lets you set it and forget it - and some people prefer that. More complex functionality inside the box can also be just one more thing that will break down and need repaired...
