This isn't rocket science people. Miller has made a machine that may be daunting to look at and to think about what all those buttons mean. The simple fact is that the manual tells you the function that each one of those buttons performs. Is it that hard to read? I may not have "understood" everything about my Dynasty when I bought it but I can tell you that I did read the manual, called Miller Tig Services when there was something that I didn't understand, and just got my ass to work using the machine.
It really isn't that difficult to understand what this machine does.
