I will definitely be moving up to another Dynasty 200 or 350......I am making a custom computer desk that houses all the components. The top is 3/16 with 3/16 tabs(5000 series aluminum) and although I successfully welded them on the Diversion did not like it. It worked but I had it floored just to establish a puddle. Great on small stuff though just need some more umphhhh....will update with a couple pics...
