i defiantly agree with Frosty and Glenn, while its fun to get a little mig welder and play on the weekends, when your using tools that move and swing large parts you have to really know what your doing. i work at a job shop repairing other peoples broken mistakes. some of them have killed people because of sloppy welding.(safety bars around a large open floor mixer) the bars were not put in place right and the welds broke too.
sign up at your local tech school, great places to learn the basics
