I recently purchased a MM211 Auto-Set with MVP and so far it has been a great unit. While the Auto-Set feature works as advertised I have found it runs a little hot so I have been setting it manually like I am used to. But it got me thinking about how the Auto-Set works and exactly what it does. I could not find a good explanation on the Miller site so I sent Miller Tech Support the question and have not received an answer. I am guessing that it somehow automatically sets the voltage based on the selected WFS.

So here is the question. Exactly what does the Auto-Set feature do and how does it work? I know how to use it I just want to know how it works.
