Pat I've been using a 110 version of the Hobart for a year now. More than enough umph for sheet metal, but the cycle times aren't as good. If you have 220, makes sense to go that route. Have heard excellent stuff about both Miller and Lincoln, Don here recommended the Hobart a while back for the price and usage I was looking for, and I have to say it has done everything I have needed it for, for a great price.
