The Valuable resource that is the Welding Calculator on the Everlast site and Miller Site post the Argon flow rate in denomination of CFH...However the regulator that came with my Everlast PP205 is in LPM.

Can anyone give any insight into the appropriate conversion? For example aluminum 1/16" with a corner weld calls for 15cfh...what is this in lpm?

I set my 40 argon tank to 17, however this was in lpm and not cfh and my argon tank ran out in 1 hour

Thanks for any feedback.
