I bought this new. Took very good care of it. Still looks like new. It is set up for gas. Includes flow meter, no bottle. Requires 125 volt, 30 amp circuit. Comes with a spool of innershield .030 wire. I have welded 1/4" mild steel with good results. It has full variable dials, not four position, for fine adjustment.
