The Stovebolt Site Forums The Shop Area Paint and Body Shop MIG 101 - Gas?

Go to welder's gas supply house, check phone book. Even if you "buy" the tank for around $75 or so, it will not be a new one and you just trade it in when empty and only pay for the gas that way. Some farm stores have new tanks, you have to go fill them still, or trade that nice new one in on a beat-up returnable like above. The mix of 75-25 is the best. Think with gas you only use .023 wire, check your manual. .035 is usually the core size wire. Don't forget to change your wire drive rollers to right size wire. Gas sheild makes better/cleaner welds. You still have to knock slag off the core wire welds, just not very much of it is all.
