Fire extinguisher bottles.

[Mr bump]

Being a builder, we do a lot of refurbishments and I seem to have amassed a collection of up to date and full co2 fire extinguishers. Many moons ago a mate used a fire extingusr as welding gas and I must admit, it turned out quiet good, so can this be used?

 

[madkayaker]

Yes it can but you need to turn bottle upside down so you get vapour out instead of liquid

i used to get my co2 extinguisher refilled by the fire extinguisher company whilst it was indate, worked out cheaper than pub gas cylinders

 

[Mr bump]

I've always managed to get a boc bottle with argon mix, but my source has dried up due to new bottle rules. Does the co2 weld as good as argon mix?

 

[DrNik]

imho no ,spits and farts doesnt seem to penetrate as good, but thats only my opinion

I have had no problems using straight CO2:

That was done with a Clarke 130EN. Almost no spatter. It does blow holes easier.

How well it works depends on the welder and your technique. It is more sensitive to torch/work distance due to the lower workable wire speed range..

I've had a word with my local pub landlady and she's ordering me a good sized Co2 bottle next time. I've looking into the Adams rent free bottles, I know there's a separate thread about gas and suppliers, but is the Adams rent free deal a good one? I'm open to any Nottingham members to where they get their gas from. With working away midweek all the time, its hard to find a gas supplier open on a Saturday.

Is it just me or do these welds look like some sort of fossilised fish?
