Chris Davies Posted April 5, 2011 Share Posted April 5, 2011 I need a gas bottle reg (argon CO2 mix for mig welding). I have had in the past an old mig welder that came with a pub style CO2 bottle which works but the clocks are broken. I also have 2 or 3 other pub bottle regs in very good condition. Will these do for my argon/co2 bottle. Cheers Chris Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted April 5, 2011 Share Posted April 5, 2011 Personally, if in any doubt I'd buy a new regulator. They're not massively expensive, and several hundred bar is not worth messing around with. Quote Link to comment Share on other sites More sharing options...

Cheers Chris No. CO2 bottles have different fittings to welding gas bottles - also the pressures are much lower in CO2 bottles,so the range of the pressure scale would be unsuitible.

CO2 has external thread on bottle. Ar, ArMix have internal thread on bottle. Fuel gasses have reverse thread. Quote Link to comment Share on other sites More sharing options...
samd35 Posted April 7, 2011 Share Posted April 7, 2011 You can buy adaptors to fit a CO2 reg onto an argon mix cylinder and the regs do work as i have a CO2 reg with an adaptor on my mig. from memory machine mart sell them. Quote Link to comment Share on other sites More sharing options...
