Finally got my CO2 tank! but...

[kagentx]

i'm so happy i finally got my Co2 tank after months and months of thinkin about an extinguisher... the welding supply store said that the extinguisher can't take the pressure of the CO2 so i just got a 10lb new one for $70... anyways
i have the milwaukee all in one unit, but does it require to have a check valve or is it already built in? don't want anything to flow back into the CO2 tank now....

I'm not sure if it has a check valve or not but you do need one. And the standard plastic ones don't work. And the welding store was lying to you. A CO2 fire extinguisher HAS to take the same working pressure as any other CO2 cylinder.

the milwaukee does NOT have a check valve built into it.
and you'd have a bigger problem with water flowing back into the regulator...I'm told any liquid (water or CO2) that gets in the regulator will ruin it. Not can ruin....will ruin.
