"Your not going to get any decent welds out of a machine with out shielding gas..."
Well, that depends....some fluxcored wire is designed to run without shielding gas. They use this type of wire when erecting buildings, because it can tolerate a slight breeze. It generates it's own shielding gas as it is being consumed, just like a stick electrode.
Here are a couple of welds that were with a self-shielding fluxcored wire...and the welder was a cheaper end 110v, 135amp wire machine....
