problem with a regulator! !!

[Piero]

Hi

I am doing a spot of mig welding for a guy I known.
We are using his mig welder and gas.

When I first took on the job. His mig had no regulator so advised him to buy a new cheap ish one.
In the mean time I lent him one of mine.
Every thing worked quite normally.
Then arrives his weld equipment regulator.
The CO2 Aron mix is fast running out!!!!!!
It was due a re fill so that waz taken care off.
New bottle and still a fast declining volume! !!!!

Changed the regulator back from cheap o to my boc reg and gas consumption is back to normal.

Can confidently conclude its the reg.
But has anyone ever experienced this??? And how can it do that???

Either the regulator is leaking somewhere or the flow setting is different.
I'd check the flow at the shroud with a peashooter to see if it tallies up with what the reg is showing as a leak should be pretty easy to find.
Is the scale on the regulator the same on both or is one set to say 10 l/pm and the other set to 10 cf/h or something like that?
Can you hear any noticeable difference at the shroud?
