I found this site so useful, I just wanted to add my 2 cents. I have tried welding but gave up. I have a car that needs frame repair so I did some research and found a mig wire new to the market from Harris. It is called twenty gauge, it has a powered core and will not burn through thin metal. In a couple of days of practice I am now doing decent welds. With some more practice and more good information off the net, I am confident I can do a good job doing my own repairs. Has anyone else tried this product?
