Mike & Dave,
That's where I'm headed, but I'm on a bottle exchange program so the time it runs out will be the time I have to stop work, load up the bottle and make the 15 mile drive to the supplier.
Dave, before I posted here I was looking for info on the net and ran across a site that pointed out that in general MIG's using only a pressure setting waste as much as 80% of the gas by flowing too much - 2.5 to 5 times more than is necessary for good shielding. Your ball flow meter is probably a good idea.
