I work in the Industrial Gas business. If you put your tig gas (argon) in the gas tank you will have a 50/50 mix of argon/fuel vapor. If you purge it again you will have a 60/40 mix and so on. Dryice CO2, when it turns form solid to gas it builds psi, giving you a continuous purge. Let it sit in there for at least an hour. Please don't use any other "welding gases" you would use 200+ feet before it would be safe and even then?
