Well, seems like the job is going to be giving me a lot of time off for the month on May. I've always wanted an undertail exhaust set up. This seems like the best time to do it. I was wondering if you guys could tell me the differences in welding? What is TIG welding to MIG welding? I need to purchase a welder but would like something cheap as this would be the only time I use it. I ve got an idea of what I would like to do to the bike. Just need the right equipment. My bike will be having a complete make over to it in May. New paint, wheels, and hopefully an undertail exhuast.
