I am new to welding, I recently purchased a new miller 211 mvp, (about 1 year ago) I seems that the welds look like honey combs, the tank shows pressure is at 1500 I don't think that empty, I have used almost an entire 11 lb roll of wire, it is very frustrating, I have argon/02 set at 15lb any advice. Thanks decaro

gas settings...
First your gas is likely 75/25 mix between co2 and argon. I would set your cfm at 25. Can you hear gas coming from the nozzle of the gun when you pull the trigger?? If u can turn up the gas until the porosity goes away. Fyi the factory supplied regulators are junk. Also have you tried different gas? Maybe u have the wrong or poor quality gas.Originally posted by decaro View Post

Its CFH, and yes 20-25, If you do indeed have 98/2, thats a spray gas, no short arc with that one..Comment

Thanks guys for the quick response, it ends up that the gun somehow got pulled out partially and I had no gas coming through. I welded an truck body with this welder and came out great, all the sudden I couldn't weld for sh%^. your responses fixed me right upOriginally posted by big mike View PostComment
