Gas co2. Question

[philb]

I get my pub gas bottle refilled co2.. But in use after just a few mins the guage freeze up and output of gas stops causing welds to be rubbish or OK for first minute... The pressure reducer is one with vertical plastic sight guage with knob to adjust output

Your bottle probbley has a dip tube,so is pulling the liqued CO2 up. It's the same with using fire extingushers (as I do) so you end up having to use bottle up side down. Even then you may still get frosting up of the gauges.

ps you don't have to high a flow rate do you ?

Does your bottle have a white stripe painted on it?
You need a pub bottle without a stripe (or a co2 fire extinguisher - i used both, and they both fit the same gauge)

I was told that's a stripe is a sign it has a dip tube inside, explained above.

Pub gas doesn't normally have a dip tube?
It would take a lot of gas usage to freeze a reg normally, as advised, is your flow setting too high?

Just checking but you should have a Regulator before the one with the vertical tube with a ball in it.

Ie, you should have 2 knobs that you can adjust?

Open the ball Gauge right up. Open the first Regulator until the ball is near the top, close the ball Gauge until you get the desired flow.
