    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 up

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

Thanks decaro
    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.
