Thread: L m/n to CFM

  1. #1

    Default L m/n to CFM

    Hi
    I have a new everlast tig and Mig would like to know the conversion factor from the L m/n on the regulator to CFM which I am used to. I ran between 11 and 15 cfm on my old Mig.
    Thanks
    Ray

    I was under the impression that it was the opposite and had the L m/n set at 20 or so. now I know why I went thru mi mix so fast.

    And I can't find 'technical-bulletins-tips' part either in longhand.
    Somewhere I read here that there is a ratio of 1:9 between CFH and LPM.
    Is this correct?

    No, its 1.9:1

    Is that 1.9 liters/min. is the same as 1 cu. ft / min.?

    1 ft^3 = 7.481 gal and 1 gal = 3.785 Liters, so 1 ft^3 = 28.32 Liters.

    To convert from Liters/min to ft^3/min, divide the Liters/min number by 28.32.

    To convert from ft^3/min to Liters/min, multiply the ft^3/min number by 28.32.

    If you meant ft^3/hr and Liters/min, then the conversion factors become 1ft^3/hr = .472 Liters/min:

    To convert from Liters/min to ft^3/hr, divide the Liters/min number by 0.472.

    To convert from ft^3/hr to Liters/min, multiply the ft^3/hr number by 0.472.

    Here is it for people who are lazy.

    Anywhere from 5.5 liters per minute to 8.5 liters per minute will be fine for your indoor tig welding. Tune it in that range.
