After working (playing!) with MIG for a while on stainless/mild/alum, I got cocky and bought a Dynasty 200DX.. I've wasted countless hours and bottles of Argon burning through various metals and I can't weld with this thing worth a crap. Any advice on what/where I can get some good info/training to properly use this? I'd really like to do some beatiful work on stainless & alum, but I guess I have to learn to crawl before I can walk here...

Any recommendations on online courses, videos, community colleges or seminars in or around Chicago? Any tips on what the best course for learning would be? I've seen classes ranging from $900 - $2200 and while I'd rather not spend the upper end of that range, I guess I'll do what I have to... I'd appreciate any advice you guys can offer. If learning from videos/books is realistic, that would be nice too. Thanks!
