I've talked with my uncle who has been welding for who knows how long and said they have a lincoln SP-100 they use for small stuff.
So I'm looking now at the Lincoln Sp-140C & Miller 140 (autoset or without autoset).
They work on 110. I don't anticipate using it a lot, and would primarily use it for brackets & other such stuff. I want to fab up a bracket for my AWIC pump....which is why I want to get one now.
I may look at a used one....but I need to do some more research.
Anyway....just thought I'd share....if you have comments post away
