This is a myth.
"Industrial" grades are actually *cleaner* than beverage grade. Welding
processes cannot tolerate contamination.
CO2 tanks deliver vapor over liquid, which purifies further by distillation
I wondered if anyone was going to suggest the do it yourself route. Here is
a link for just that purpose if you're a DIY type.
And I copied and saved some comments (I think from an old thread) about
installing the regulator;
"For me, this was quite an educational process, I didn't understand that
there was any difference between a primary and secondary regulator. I
thought one was just down stream of the other. I didn't realize they were
rated for different pressures.
As the gas is going directly into the regulator, it must be rated high
enough to handle the pressure. The typical secondary regulator is only
rated for 100-250 psi max. CO2 tanks put out 800+psi. The damned thing
could have blown on me.
The next thing is right-hand or left-hand threads. Virtually all paintball
equipment is right-hand thread. It looks as though primary regulators are
mixed between RH and LH.
So, you want a regulator rated for well in excess of 800 psi (the one
mentioned above is rated for 3,000 psi) and that has right-handed threads.
The only thing this one seems to be missing is a check valve, which are
easily accessible and installed. Beer here, Mike. After looking around on
their site some more, in the replacement gauge
it has a RH high pressure gauge listed for Norgren and Chudnow brands (the
one I ordered was a Norgren) and LH for Micromatic, TapRite, NADS, and
I saw that part of the site, and I almost ordered the same regulator, but if
you could confirm that the part where the HP nipple, which goes to the CO2
tank, is indeed right-handed, when you receive the regulator, then I would
appreciate it. Well, I got it today and the threads are indeed right handed.
I had no problem removing the tank connector and installing the paintball
tank setup. http://www.schwedhelm.net/brew/biggasser.html Now I just need to
get the tank filled to try it. Also there was a thread about the regulator a
while back. The regulator I used was the economy regulator for $20 at:

I've seen plans arround the net for that very thing and also for a
filling settup that uses a 20Lb CO2 tank mounted upside down to
dispense liquid to fill the paintball cylinder. I'm not sure I have a
pair big enough to do that myself but the plans are "out there".
That's kinda a neat little set-up!
A friend of mine had two draft taps on the front of his fridge. He
dissected a soda fountain dispenser to get the hardware, and ran the
tank and reg right beside the fridge. Soda kegs hold pretty close to the
amount of brew you get from a U-brew kit. :-)
I have been looking at making a paintball tank adapter for my MIG
welder. 20 oz of CO2 at the local supplier is about $10, and a fill for
a baby bottle from the welding supply place is around $50, last I checked.
For the amount of use I get out of the welder, it makes more sense to
use what is cheap and available, even at a slightly higher cost for the
consumables, I don't have the need for a large enough tank to get the
When I was checking, I could buy CO2 for a bit over a buck a pound, to
fill a 20 pound tank. Most of the paintball places were charging 50
cents an ounce or a bit more to fill tanks. <shrug> No one ever starved
to death buying low and selling high. That's retail.
