my team mate asked me a question today, and i dont know the answer for sure, any idea mario/woody?

on a small welding bottle (co2) like youd get from halfords, does the outlet valve do any kind of pressure restriction prior to the regulator?

I think (was fairly sure) no, but im not 100% sure. my team mate wishes to use a gas draw fire extinguisher filled from our robot co2 supply, instead of buying new welding co2 all the time, but is worried about putting the reg onto a fire extinguisher because he heard welding bottles have pre-regulator reduction, and doesnt want to damage his reg.

If woody/mario know either way, please let me know.
