Argon Regulator to Co2 Gas

[Umar1808]

Hello everyone I'm setting up my mig welder at home for some light fabrication work from time to time. The welder is a castomag 180 and came with an argon regulator. I've bought a co2 pub size bottle which has a male type thread. I've seen adapters on eBay and machine mart sell one which allows you to use a co2 regulator on an Argon bottle. I found an adapter on eBay for my purpose which is female on both ends, they're not cheap for what they actually are!

Question is about safety will I be ok buying the adapter and running my argon adapter with co2 or should I buy a co2 regulator. The only reason I would like to keep my existing regulator is that it's a BOC unit and has a flow meter which is handy and is in very good condition.

The shop I bought the gas from sell regulators but had no idea that adapters existed and mentioned that they wouldn't be safe (a bit of a bodge in the guys words)

Thanks

Never used it but my co2 one came with an adaptor to make it able to fit argon (male fitting)

Co2 cylinders are lower pressure than Argon so it should be fine

Thanks, I read somewhere something about co2 gas freezing? Would this affect the argon mix regulator in any way?

Regulators will ice if you are flowing lots of gas through them, hobby welding shouldn't be a problem but the big industrial machines have bottle heaters.

at the risk of bumping the thread, my regs over here are dual -you can use em for CO2 or argon and they have an outer scale for argon and an inner scale for CO2. Maybe its CO2 mix they are good for-dunno.
Just wondering if they are available in the UK, the french ones will not fit UK bottles.
