Small Welding gas bottles

[Cue]

I got 2 of these small gas bottles from my Fathers Estate and dont know where he got them. They are about a foot tall, 4.5cu ft. new, and full and I would like to use the gas. one is Argon and the other is Argon/C02. They have a small threaded fitting on the end that is a little bit larger than a regular air fitting. Does anyone know what kind of fitting it is or some sort of adapter that I can get to use with my welder?

I expect that those are for MIG and TIG use. Your local welding supply shop should be able to fix you up with whatever threaded Fasteners you need. I am not a proficient experienced welder just a hobbyist

 

[Cue]

Yes, they are for Mig and Tig, looking for fittings, or the names, I can order online, or what they are called as welding shops are not close.

I have been welding for my entire adult life as my main profession and I have never seen a fitting like that on an argon cylinder.

You will need to ask the gas supplier, but I suspect you'll be told that you're barking up the wrong tree.

That also isn't very much gas. You will run out in just a few minutes. Most welding is done at about 15-20 cubic feet per hour. If you go as conservative as you dare at 15 CFH, you'll exhaust your gas supply in less than 20 minutes. That's assuming zero pre or post flow and that you use every last cubic foot of gas, which you rarely can . I would estimate you have more like 15 minutes of welding at MOST with that amount of gas.

Yes, I know they wouldn't last long, I just would rather use them up than just letting the gas go and throwing the tanks out. I was hoping I could find some sort of adapter so I could disconnect my large tanks on the welders just to use them up but its probably not cost effective.

There are small Argon tanks used for these Jewelry welders, but I dont think they were around when my father got these tanks as they are old, so I dont know what they were originally for.

Here are some links to the Jewelry welders and small tanks, they have a regulator as well but its $100, so not worth it for me.

You will immediately find out that nobody is going to fill a cylinder that doesn't have a current inspection date stamped into the neck.

I am not trying to fill the cylinder, I am trying to find an adapter so I can use up the gas, then throw them away.

Your gas supplier might take them in trade for something that you want if they have a use for small tanks. I traded a bunch of small tanks for one larger tank because, at the time, they were short on small tanks.

 

[Cue]

It is 1/8" NPT threads on them, guess ill hold on to them and ask the welding store the next time I go in if they have some sort of adapter that isnt too expensive or trade them in.

 

[dr_clyde]

I think you'll find the adapter will cost you more than the gas inside is worth, but you do you.

 

[Cue]

I think you are correct, maybe ill use them for target practice at 300 yards lol

I work in the industrial gas industry and for all intents and purposes those are the making of bells and nothing more.

Could be lecture bottles. Used in chemistry classroom for demonstrating.

They would make good wind chimes......

Highly unlikely. Those are usually not argon and argon/CO2.

 

[BigMike782]

About 15 years ago a customer brought in a cylinder of argon/CO2 that looked like a 20lb propane cylinder.
It had a fill tag for agon/CO2 and was a CGA 580. I found out that it was a very short lived promotional type thing Mittler Supply tried so there are some odd ball low pressure cylinders out there but very far and very few between.

True, only use I can think of for one that small.
