I use a Millermatic Passport Plus with a spool gun that is wired for 110v it welds just as well as my Millermatic 252 220V. I have a magnaflux system and test welds when ever I am concerned on overhead welds and hard to reach areas. The welds from either welder are very strong and very clean. I know nothing about the cheaper welders never used one so not much more I can add to this board.
