Disposable bottle regulator - flow rate?

[visor_down]

hi all,

i have the cheapy brass regulator that came with my SIP for the disposable bottles. Now i have always fully opened it and then a quarter turn back. Does anyone know what the flow rate would be off these?
is the above the right setting for them?

thanks

They vary a great deal. Some don't provide even 8L/min even fully screwed down. Way to test them is to buy a peashooter to measure gas flow at the torch like this: http://www.mig-welding.co.uk/forum/showthread.php?t=7449
