Get a book on welding. Any store that sells welding equipment will have
a good book. Libraries, also. I have used my 225 amp welder to make all
kinds of stuff for my plant and for use around the shop. Lots of work
tables, a table saw base, frames to hold lights for work benches. I
have cut steel channel, heated rods for bending with the carbon arc
torch ( before I got gas equipment).

I have a 50 amp service/breaker for the welder. I think that is the
minimum.
