Oxygen

[Neder/Brit]

Hi people I have a question, I have seen on the net that people use co2 tanks instead of compressors I assume these are divers tanks. I my self work in a big scrap metal yard cutting with gas & oxy. My question is can I use the oxy that I use for cutting to abrush.

[HerpHandler]

im sure you could use anything that would give you a constant psi, but with oxygen being so darned flammable I wouldnt chance it.

I have used Co2 tanks many years ago. They have clean dry air.
Only problem is when you get near empty the air can freeze. I got tired
of refilling all the time. For doing street fairs and where you are cramped for space its cool. I don't use any kind of flammable products. To risky.

The best air to use is Nitrogen, Clean Ultra Dry Air, I used it before, but the cost over time drove me to buy a compressor with some awesome coalescing filters...... Also Nitrogen is an inert gas so it's not explosive

Just to clear up a miss conseption ... Oxygen is NOT Flamable! It however, is required for Oxidation to happen (fancy word for fire) So, put Lots of what is need to start a fire in a place and add a little heat and boom stuf that normaly does not burn goes up like kindling. If levels of pure O2 get go high you get spontanious combustion.. so truth be told O2 does not burn but causes things around it to burn.

Your Right AixGuy, But if a spark ignites, or maybe cigarette, I'd rather be near a N2 Tank vs. O2 one...

In the long run, IF you don't have a noise or electricity issue, you'll be happier with a compressor with a tank.

Oxidation is also a fancy word for RUST, I use oxygen-acet. tanks for welding and cutting steel for a number of years and did not start any fires with the oxygen except on purpose, do you know that water will burn

[Neder/Brit]

Well people thanks for the input, having taken various safety courses over the years I know that a high concentration of oxy will make an ignition point higher I have seen a work mate blow dust off of his overals with his cutting torch before a coffee break and about to light up a ciggie, luckily he was stopped and his overals were put on the ground and a match thrown on them. Split second combustion. To be honest I feel a bit stupid asking the question in the first place because I have learnt about these things. But thanks anyway.

[heartless]

dont ever feel stupid, Neder - you learned about it in a different context - sometimes we need a bit of a push to apply that knowledge to unfamiliar areas.

[aixguy]

I was not trying to make anyone feel stupid. I had alway believed that O2 was flamable as well, until body shop in Automotive school where it was explained to us. Sorry if my post seemed condisending. I just found the knowledge enlightening when I learned it, since it made no sense to me that what we breathed was flamable.

[heartless]

aixguy - you didnt, no need to feel guilty - like i said, sometimes we need a push to apply current knowledge to a completely unrelated area, you supplied that push.

we should learn something new everyday - even if it is a small thing - or applying something we already knew to a completely different area - it is learning & that is always a good thing.

Don't ever stop learning!

[redneck]

the water that we drink & air that we breathe contains oxygen & hydrogen , hydrogen will burn , water & air will burn if the heat is hot enough [in laboratory control ] nothing will burn in a vacuum which is why space rocket use oxygen tanks and a rocket fuel
I hope that nobody feels stupid because of a misinform public idea,if airguy had not said what he did -I was going to

[Bahamut]

JUST AS A NOTE!!! The reason they put the sticker "USE NO OIL" on O2 Cylinders is that when you compress O2 and inject any kind of oil (oil based paint) the oil combusts!! This is how a diesel engine works. Air is compressed in the cylinder and oil is injected then Boom it ignites. So unless you're going for the flamethrower effect on your brush DON'T DO IT!!!

Have never heard of a Air Brusher having any Co2 tanks blow up,they have been using them for over 50 years. The one thing you must have is Co2 guages to regulate the pressure.

Ispray, I hope that you not confusing Co2 with 02 , THE 2 NAMES is confusing to me
Oxygen in the air & rain drops will cause steel to rust, I seen steel so badly-rusted that it would keep on burning after I cut the steel into smaller pieces

[Ispray]

Not confused, said I never heard of an airbrusher having a C02 tank blow up. Have the tanks filled and checked where they fill tanks for welders or find someone that owns a business that uses fountain drinks or beer on tap and rent a bottle from their distributor and exchange the bottle at their business.

[redneck]

I was welding close to ox/acet. tanks [1970s] and the acet. were leaking at the seams-were on fire-but a quick exhale from me blown the fire out

[Neder/Brit]

I must say for someone who is still waiting to get stated (me) I seem to have sparked off quite a discussion

[redneck]

neder, you had to overlook the time delay in answer your question, i may be mistaker but recall someone using a oxygen tank to supply pressure to a paint spray gun,before you try using oxygen supply to airbrush I advise you to talk to the fire dept or insurace agent to find if a accidenent will be cover

[Dorian]

Hi Neder, I'm a newbie here and although I haven't tested it or been around to know if anyone has done this already, I was enjoying the discussion, so thought I would chip in....hope you don't mind, as you have probably already decided which way to go!

I would like to echo Bahamuts post and advise extreme caution. I have done courses in gas blending and was involved in the mixing of nitrogen / oxygen for a while. You will have to be extremely careful with all materials used particularly types of oil/grease.

Also, just for fun:

The TV show Mythbusters did an examination into whether or not the story of pilots being decapitated in the explosion caused when their hair gel reacted with the oxygen breathed through their masks....

Myth Conclusion: Busted. There was no explosion causing decapitation. However part of the myth was plausible. Hair cream, hair and oxygen are flammable.

Although if that's your picture, then you sport the same hair style as myself - so there's one less thing to worry about

Hope you don't mind!

[Ispray]

You can use your search engine and search Co2. I think the question was about using Co2 for airbrushing and it is safe to use it for Airbrushing but you must use a Co2 regulator. Can also check out the search at westcoast airbrushing and get the views from some airbrushing leaders.

No Dorian I don,t mind at all the nice thing about forums is that everyone can have a bash at giveing people the benefit of thier knowledge or lak of it. As far as hair styles go (son you aint seen nothing yet) if you hang around long enough on this forum you might just get a glimpse of what lies beneath the facade. Happy spraying.

[Bahamut]

CO2 is Completly safe to brush with, as long as you aren't in a confined space. Be advised though if you use to much pressure without enough volume of CO2 the gas will solidify (turn into dry ice) and you will get variance in pressure until it has time to vaporize again.
