I was planning on investing in a small welding machine. On the future, I intend to use it for car bodywork repairs, but for now I'll probably be practicing making small tools.
For a number of reasons (i.e.: available money, lack of experience with welding and physical space), the two types of machines that seem to fit my current situation are regular stick welding machines (either transformer or inverter) and gasless MIG welding machine. I heard about the latter through a bodywork professional, and it seems to be just a welding machine that behaves like a MIG (wire being fed to a gun, adjustable wire feed speed and current) but uses no inert gas.
Apparently, the advantage of the gasless MIG is being easier to use on small metal sheets, just like some that are used in car body panels. It's a little more expensive than the stick welders though.
I was wondering if the gasless MIG is a good investment or if in my case I should just stick with the stick welder (no pun intended :p).
