    I think you mean CFH but anyways. I used to turn my chamber purge on at around 10 CFH and my torch set to 15 CFH, try it on a test piece first and make sure you have no oxidation of the weld or HAZ (heat affected zone). If you have any oxidation bump up your chamber CFH a bit. What size gas cup are you running?

    It is the same thing but in metric

    L/PM Litres Per Minute

    A litre is a Volume measurement already

    CFH- Cubic Feet per Hour

    a foot is not a volume so we have to then state it as a Cube to show volume.


    Most likely your regulator gauge has both measurements on the dial- at least all of the ones I have do.

    A cubic foot IS a measurement of volume.
