Hi all.

Just wanting to see if there is anyone that has got a empty co2 fire extinguishers that they dont want or no where i can get 1. Has to be in good order as it is going to be use for co2 for a welder.

Ctest in CHCH will convert it for me.

Install and buy Hand wheel valve $56.25
Test cylinder and valve $42.00

Was told to go there from the shop i brought my welder from and also told me a lot of home users do it.

Thanks

Empty extinguishers? I thought this was going to be a Norton's commercial.

I have a picture thereof now if the OP wants.

I would not want to waste bandwith by putting it here though.

It's a 2 Kg when empty which it is. Normally contains CO2 for putting out fires and weighs 3.2 Kg if you fill it.

Could be a bit lively - LPG stores at 50 ~ 200psi at storage temperatures likely to be encountered, CO2 is filled to around 2,000 psi.
Even in metrics, things could get a bit expansive.

Yes. In that the flying chunks of metal will expand your head. Off.

Some of them could widen your views a bit - others could bring you up short

Another good use for old fire extinguishers is making a gearbox/ diff oil filler.
Cut the Schroeder valve from an inner tube and silver floss into the neck of the extinguisher.
Just pressurise to around 130 psi with shop air.
The high pressure sure moves the thick OEP 90 along.
I had to change the the o ring as the 90 oil deteriorated the o ring material for CO2.
ACHTUNG dont unscrew the bottle before depressurising (with a match or similar) could get messy.

I'm surprised you have not already made a bomb out of one.
