Method Why people only talk about helium and nitrogen but not argon?

[Alreadylate]

I have understood that Helium, Nitrogen and Argon are exactly the same when it comes to the exit bag. But here everybody is using regulators for argon, in order to use nitrogen cylinders... Why not choosing directly Argon? I dont know how it goes in your country, but I see getting the three of those gases is easy they are on ebay. I also understand people is getting Ar regulators because they are the only ones that show flow min/L, maybe those people don't have acces to Ar. In any case I'm curious.

I have a cylinder of 100% argon. I weld and use pure argon for aluminum and an argon/CO2 mix for mild steel. I also have a spare cylinder for each. Argon works fine. Several years ago I had to euthanize a wild rabbit that was injured and so tried argon to see how it works, it was quick and peaceful

I bought one that is Argon 4.8 which means a purity of 99.998%, it's for welding, I guess that's ok...

That's what you want

I tried so hard to inflate the argon exit bag but it kept failing. Are you planning argon?

Argon is my inert gas of choice because it is used as the shielding gas for welding aluminum and it is easily available to me. Nitrogen is another option that I've had in the past. So if I were to use inert gas as my method to ctb I'd use argon or nitrogen.

What do you mean it is not filling your exit bag? Do you have a leak?

Hey so I'm an old timer here and back in 2022 I tried with all my might to make argon and exit bag work but had serious complications. Found out Agon was the most difficult one to use and others also struggled. No leak. Made a bajillion exit bags. Only time it sort of worked was using the headband methods. I documented everything on my old posts.

I wonder why it was so difficult?

There are claims that since argon is the heaviest it's much more difficult to utilize with in exit bags. Unfortunately it's the one gas that's easier to access for normal people.

I purchased a combination flow and regulator meter from Harbor Freight for less than $100. ( Brand: Olsen Item # 63789) I can tell you the flow rates are not identical for different gases because they have different specific gravitates. First of all you want 15 L/min flow rate, not 25. Secondly many meters show you flow in CFH (cubic Feet per Hour). YOU WILL HAVE A DIFFICULT time finding one that shows LPM. To convert LPM to CFH you slightly double LPM to get CFH. For instance 15 L/min equals 32 CFH.
The meter I have shows a scale for CO2/Argon/Helium. When you look at the Helium scales and eyeball the 32 LPH, and draw a line over to the Argon scale, it lands on 12 LPM, And then when I go to the carbon dioxide scale the same place on the ball comes to 14 LPM. So you cannot simply substitute the flow rate of one gas one-for-one for another gas because they are all different densities. The pressure gauge on the other hand is not altered by the gas you are using. My Nitrogen tank is 1750 PSI and my pressure meter shows that pressure when I connect it to my tank. as you use your Notrogen or Hellium the tank pressure will slowly decrease but that will not alter your flow rate until the tank is almost empty. If you have a 20 cubic foot tank and you are flowint 32 CFH, you can see the tank will last over an hour-plenty of time.
WOULD SOMEONE BE WILLING TO PUT UP AND EXACT MODEL NUMBER FOR A COMBINATION REGULATOR AND FLOW METER FOR nitrogen AS I DID HERE FOR HELIUM?

Hello, everyone is talking about a regulator for the exit bag, and I am wondering exactly what its purpose is and whether it is necessary to purchase one in order for it to function effectively without causing any damage. Thank you in advance.

I wonder why it was so difficult?

argon is pretty significantly heavier than air, an argon leak in an industrial setting is really dangerous for that reason because if someone passes out from hypoxia there's not cleaner air near the floor
