So I'd like to be able to make and fix my own frames and don't have the equipment. I don't really want to fill tanks all the time so would a flux core welder work? What amperage should I be looking at? Is there a good, cheap brand to go with? Will I be able to plug it in a normal wall outlet so I won't have to run a new line to the power box? Thanks for any advice. Just trying to teach myself something new.
