Except the industry has loosened up on some of the definitions. MIG is a catch-all for wire electrode. Then you get to the type of wire, inner-shield, dual shield. I personally use straight CO2 for hard wire and dual shield at home, but at work we use an argon/CO2 mix with a different wire designed for mix gas.
As far as what the OP is asking, a 110 inner-shield welder will do him just fine, but a little buzz box stick welder may work better since it may be less expensive and fewer parts required. Cable and a clamp vs whip, nozzle, diffuser, tip, drive rolls. JMHO
