At least, what I buy round here does! Re the gas, I originally went to a welding sales place (many years ago) which fitted me up with a regulator, pressure gauge, and appropriate connections to screw to a pub CO2 bottle.

OK for beer but not for welding. So I then bought a fire exinguisher, the screw fittings fitted it, and I just have it refilled from time to time (every couple of years or so. �15. So I own the 'bottle' and buy the gas. So so much cheaper than the little bottles that come with the welder. When the bottle's time comes up for pressure testing then I probably buy a new one. Rob

Interesting. Maybe I could go back to the pub bottle. I wouldn't have the problem with pressure testing then. Rob
