Maybe I am asking too much but if you can give me some idea of what it is and how to buy or build it, would be appreciated.

There is just so much out there. I don;t know where to look for what I purchased.

 

This http://frikkieg.blogspot.com/ was actually the welder I purchased the partial kits for. I never got around to building it. Looks like the store is closed.
