Just got myself a co2 tank designed to fill small paintball tanks.

I plan to use this mostly for combat robotics and possibly
for a MIG set up when I get MIG.

I do have SCUBA experience, an air compressor and a TIG set up. But
co2 seems to be a bit of a different horse as it is stored in liquid
form.

Looking for information sources on handling this safely.
Favorite books, web sites, free advice...


Tanks :-) for any help.
