Most of those horror freight 70 and 90 amp welders dont have gas abillity. You can get lucky on craigslist in ur area for a mig with a mig with gas setup used (and a buzz box). Or bite the bullet like I did a buy a nice millermatic. I started to get the Hobart 140 at tractor farm supply as it was on sale. $269. If u do add gas to ur current welder u gotta switch the polarity
