My 210 has only 4 voltage settings on the 115 side. The 230 side has 7. Infinite control for the wire feed.
For the sheet stuff I've been doing it has been just fine so far and BTW, I'm still learning it. My old Airco AC/DC stick does the heavier stuff.
You might also check the youtube site for any models you're interested in. A wealth of knowledge is out there on video.
