I have a Hobart 210 it has the option to run it off 220v or 110v. It’s a good option if you do not have 220 currently but think you might outgrow 110. Now that I have 220 in the garage I never use the 110 option but it’s nice to have for portability.
I know a couple people with the Hobart 140 and they have no complaints. The 140 would do 95% of the welding I do. I don’t think that a spool gun is a possibility on the 140 but your tig would most likely be a better option for aluminum.
