Shielding gas cylinders

My problem with the bigger tanks is that I'm retarded and always seem to forget to shut the valve off and then come back a couple weeks later to an empty tank. It's cheaper to do that with an 80 than a 250!

Been there, done that. I have trained myself to always shut off the gas before I turn the machine off.
 
I do that all then time with my co2
luckily there's like a billion cf in 64lbs so it really doesn't matter and has gone weeks left on, probably cost me like $5 in gas lol

I did the same with a full tank of oxy and acy... amazed I didn't blow myself up.
 
OP, whatever you do, make sure you ask a couple different places. We had a smaller welding store sell out to a bigger company AirGas and they suck. They told us we have to rent bottles, their prices jumped like 30% on gas and they never have thier shit together.

We found this company called Matheson.
They can deliver to our area every Thursday and still cheaper than AirGas.
We also dont have to rent tanks from them.
 
That's because you suck at rolling it around.:flipoff2: I suck at it too. I can go about 5' at a good clip, then I get death wobble.

The folks at the welding store can rip around with two bottles as fast as you can walk. So, it can be done.


I have to show the receipt for purchasing my bottles before they will refill them. They won't fill a bottle they didn't sell or rent. I've never tried to get the bottles filled somewhere else, my LWS is 10mins from my house.


Speaking of receipts. Sigh.

Holy shit! I get my 300' bottle of argon refiled for 38$ through our work account. If it cost that much for gas here, I would stop welding.
 
congrats, now they know they can fuck you
you're just gonna get fisted deeper next time
 
Damn Skippy
I got a 225 argon tank 3\4 full , a bud dropped off for me to keep.
Just about time to play "find the schisters",
So it seems the net claims 100% Argon works across the board?
Bad idea?
I most likely will run 75\25.

Welcome to being a little guy in California.
Hope this helps the O.P.

I want to say the rent on a 250' is around $0.50 w/ Airgas. I'll check back.

Is there a way to tell what gas is in a bottle? I had a bottle that was given to me and have no idea whats in it. Its got a liquid in it with a valve that can pull gas off the top or liquid off the bottom. It has male threads on the valve.

Its not propane and doesn't have any type of smell.

Any ideas?

looks sorta like a propane tank? prob a refrigerant recovery tank
check the pressure and temperature and we'll be able to tell you which refrigerant it probably is

Does it rattle? Like there is something loose in it?

It looks like a regular welding bottle. Seems like its thinner than my 25/75 bottle.

I am going to call a welding store today and see what they say.

that's a low pressure tank, look at the welded construction
the valve say "CGA and then some numbers" on it anywhere?
OD and better pictures of outlet threads

I'm still betting on refrigerant. Probably something higher pressure like R13 (which is worth money)

That’s my guess too. I’ve seen another bottle with 2 valve handles And that’s what it was
 
That's odd, Went to look at a setup at Maine oxy the local supplier here. They will only provide a 60cf tank to an individual which will be fine for my use. I asked why I couldn't have a bigger one they claimed terrorism shit. was he blowing smoke or does it vary depending on the area?
 
Fixin to post up a "wire" question...
we are on firewatch AGAIN!
SO I am not running around with my ( tounge in cheek here...terrorist tank) to get pricing.

My LWS will only sell up to a certain size to non commercial accounts but it has been doing it way before terrorism became a thing. I think liability of a homeowner with little experience blowing their house up is more likely.

They also have a waiver you have to sign if you are going to put the tanks in the backseat/trunk of your Honda...:homer:

dude I can get a thermos filled with liquid oxygen, and that's some terrifying stuff
Happened to ask while I was getting liquid nitrogen.
you need a better supplier
