1.)Do I need a continuous regulator? Do I need a 400 dollar one from a shop or will one from Amazon do. I'm planning with argon.
Is 40 cf fine?
2.)Is 15 lpm right for argon?
3.)How tight should the bag be? I get no straight answers :[
4.)Also I was planning on doing it in a storage bin, in case there is a leak. Because of this I was also wondering if I could turn on another cylinder inside the bin with me. (I thought about using 2 tubes at 15 lpm into 1 bag but someone said that is equal to 30 lpm lol) At that point would it matter if I had a regulator on the other one, too?
5.) I, buying a O2 reader to make sure the 02 in my bag is low enough before pulling it down. Isn't 8% oxygen when it's fatal or no?
6.) Also have you Ever heard once of someone coming out a vegetable after?
7.) are there reports of argon being painful?
I'm sorry I gave you a book report to do.
~Whenever I see that puppy around here, I know it's going to be a good answer~
1. It really does not matter if the flow regulator is continuous or discrete. As long as it is an
integrated flow regulator and the flow rate can be accurately set then it is okay. Determine which connection standard applies to your geographic region. I would not recommend the cheapest nor the most expensive one. Just bear in mind that if you want to preset your flow rate, then a discrete click-style is best; on the other hand, if you do not mind setting the flow rate when the gas is flowing then a continuous flow regulator is fine. When using nitrogen, purchase a nitrogen regulator; if using argon, purchase an argon regulator. When the gas and the regulator match, there is no need to perform compensating calculations.
2. Again if using an argon regulator, then a 15 lpm flow rate of argon is correct. No need for compensating factor.
3. When using a bag, it should be loose enough for expiration (CO2) gases to escape while tight enough to maintain a positive pressure environment throughout the process. You would need to determine this through trial and error.
4. I would suggest that you stay away from any unnecessary complications. A storage bin and an additional cylinder are excessive. You only need one 20 cf cylinder for a 30-minute duration.
5. An O2 meter is expensive and unnecessary. No need to determine the amount of O2 in the bag. Yes at 8% O2, hypoxia can become fatal.
6. Absolutely not. And there are no confirmed reports of such occurrences.
7. No, argon like other common inert gases is not painful.

@Greenberg What can happen when you don't remove the regulator when it transit?
There is the possibility that the regulator may knock onto something and it (or the valve stem) may dislodge. Obviously, very dangerous. Best, G
