    Mig gas question.

    How can you tell how much is left in your gas bottle?

    My regulator has a bottle pressure gauge which stays at the top for quite a while then gradually runs down to zero, but the bottle isn't empty.
    I can still get a fair bit of use before there is none left.

    I am about to do a bit of work and i don't want to run out mid-job, mainly because I don't want porous welds in inaccessible places that I can't grind out and redo.

    Is there a way to tell his much is left?

    Also is that pattern of gauge reading common, or have I just got a cheap and nasty gauge?

    What gauge is it chief?? Ours at work are 184 each and even they read zero but still get a bit more out of it BUT the pressure drop is so low it can seem gas/no gas. Have you got a flow meter and if yes what's your flow reading??

    It's £20 job.
    The second dial tells you the flow, but that's all.

    the bottle gauge has been down to zero for weeks, but as be only been tacking stuff I vould afford to wait.
    Doing a fair bit this weekend though, and some of it is pretty inaccessible, so I don't want to run out halfway through without realising.

    I'm gonna buy a full bottle for peace of mind, but I am curious.

    Left hand contents, right hand regulated pressure to the machine. You'll often get a big more out the bottle below what the gauge can read, and you can bet your arse it'll catch you out each time, so I just get another bottle if I know I'm going to be doing a fair bit

    Yeah, I'm a skinflint by nature.
    The left ones been on zero for a while, and the right ones been fine.
