CO2

[sardine]

Is it possible to use CO2 fire extinguishers as shielding gas ?

Presuming a regulator could be fettled to fit.

yes you need to remove the dip pipe if it has one as you want gas not liquid
C02 is stored as a liquid

just try it, if the reg gets upset just turn the bottel upside down

I've got to ask why?
Why not a pub bottle? There's hundreds of pub / hotel gas suppliers to Google if you don't have a friendly landlord.
CO2 is cheap as chips, and usually no deposit on the cylinders. I get mine dropped off at the pub and pop down to pick it up when I'm thirsty.

I have some out of date surplus extinguishers, and I don't have a pub bottle at the moment, though one will surely turn up soon, and i just aquired a SIP migmate 120 saved from the scrap man, and I'm keen to give it a work out.

I'm guessing the balloon gas cylinder I have, Air products I think , could not be filled with shielding gas ?

As it belongs to Air Products, only they will fill it with balloon gas.
