I'd save up a bit more money and get a bigger unit. As the other guys said, they are very limited in their usage. A welder is an investment and I would imagine you plan on using it for more then 1 project. I'd definitely recomend a bigger unit. As soon as you use the 110 about a half dozen times, you'll allready be wishing you would have gotten a 220 volt unit and a bottle of CO-25. The flux coated wire just doesn't cut it for welding, either... As with any tool, it's always best to pay for the quality unit the first time.....
