Well you will be limited with that type of welder, yes I have used similar welders. The problem I see with that machine is that it is ac only which is not the best current to weld with. You would be better off getting a machine that has dc capabilities, watch craigslist for used ones. I picked up one of these ac machines for 25 bucks at a yard sale, just like the homie dpot one you are looking at, I gave it to my brother, they are better than nothing but if you are going to buy one I recommend a dc machine. Look for one of these, this is one of my welders that I would like to sell but the market is too soft now. These welders are very heavy two guys can not pick it up, and they run forever. The second picture is the control lever to go from ac to dc current
