It's a pretty basic machine as far as features go but I don't find pulse and all necessary, don't do much aluminum where most of that shines. It's a transformer based which takes a lot more juice to run but from playing with it Saturday a little it welds pretty good. I had a lot of consumables and all for it already and already had a bottle of argon which is both a large expense when buying a machine. I've wanted an ac/dc machine and been looking for awhile but never came across anything I felt was worth what I wanted to pay, got lucky with this one bc I knew the guy who had it, he had no use for it and I got it for a steal.
