flow rates

need opinions on flow rates as LPM vs CFH .Are all Everlast regs calibrated LPM?
I am Welding .250 wall 2x2 square steel tubing.

Yes all our regulators are currently in lpm. Multiply by 2.1 to get cfh.

Doug it depends upon whether its mig or tig and the conditions...but for tig about 7 lpm or 15 cfh and for Mig 10-12 lpm or 20-25 cfh.

Make sure you have no air movement as well (fans in the shop, welding outside).
