From what I've heard, the single gauges aren't recomended. People seem to
recommend a double gauge so that you can monitor CO2 output as well as how
much CO2 is left in your bottle.

Hope that helps a bit.

Hi,

I picked up a single gauge regulator at a yard sale last week for a buck.
The
guy said he used it for welding. It measures in l/min and cfh. It also has
0-6
bar on the dial. What kind of regulator is this? Could it be used for CO2?
If
it were broken, what would happen when I tried to use it? Big Thanks In
Advance
