I bought myself a MIG about 3 weeks ago. I spent the last 3 weeks just welding exhaust pipes together and recently started my new charge pipes. Once you find the sweet spot for wire speed and heat it's pretty easy to lay down solid welds. It can get expensive though. Buying the welder led to buying bench vise, then a 14" abrasive chop saw, that led to an angle grinder.

I'm going to pick up one of those bitchen welding helmets that are almost clear and as soon as you hold it up to a light source it darkens. Things like 250$ though.
