CO2 bottle regulator/fitting
I have two bottle fittings for my MIG - neither are suitable for my new bottle. Should I buy an adaptor for one of the existing regulator, or get a
new one? Any recommendations?
These are my fittings:
 
fitting2
 
fitting3
And this is the bottle:
 
cylinder
Cheers

Is your source one that is likely to continue? I get mine from a beer rep mate, pure CO2 but it does for me.
That bottle looks the same as mine to me so if I were you I would get a regulator that fits the bottle as that fitting is very common (but keep the
other two in case).
The regulations for having gas bottles or hiring them etc is verging on the ridiculous now so if you have a good source, stick with it!
Hpoe that makes sense!

no regular source unfortunately, but I'm not a very frequent user so I expect this one will last me two or three years.
The chap I bought it off said something about the pub gas companies introducing nitrogen into the mix to make things more difficult for people like
us...???

Take the regulator to the nearest welding suppliers they will have a pipe with the correct threads / fittings on each end.
Your argument is that its the ONLY gas bottle you have. and will (or already have) labelled the regulator as CO2.
I did this with my Argon Reg, Just a nice Dymo Label will do.
Make sure the Max pressure on the gauge is suitable.
However should be OK as the Max Bar in a CO2 bottle is only about 60Bar, as opposed to 250 Bar on an Argon bottle.
Its OK to use a higher rated gauge on a lower pressure gas but not safe the other way round.
ie DONT use a CO2 regulator on a bottle of argon etc.
This is one of the main reasons they dont like you changing the fittings on regulators.
Unless you KNOW what you are doing, as it can be dangerous and could result in a / your death!
If you are NOT 100% sure, then buy the correct item for the job. Its not worth the risk of an exploding regulator. Shrapnel hurts
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

Ifyou only do occasional welding, Halfords sell disposable bottles of welding gas and stock the fittings etc.
Legal and safe but expensive.
Didn't know about beer companies changing the mix, gits, they get paid for each fill anyway!
Good luck.

I used to use the halfords ones - too expensive and they don't seem to last very long.
This looks like the kind of thing I need :

Edited to say - but obviously the advert doesn't state the gas and max PSI it's suitable for. My bottle is filled and around 50 PSI

They put nitrogen in to make the bubbles smaller in the horrible beers like John Smith Smooth, nothing to do with making it awkward for welders. Soft
drink and fire extinguisher places use pure CO2.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
