Compressed CO2 Low - Need help

Compressed CO2 is low, need help replacing, forgot how to replace

You mean argon?, we just opened a new bottle earlier this week. Check the gauge on the lower manifold in the welding area, it should read about 150 psi, and make sure the ball valve lever with the hose clamp that feeds laser is open (lever inline with pipe)

Where the manifold goes through the wall to laser there is a regulator that is way oversized, it needs to be barely turned in to get a gently flow. Ive found it cranked high so the fire supression guns act like high pressure blow off guns, argon is too expensive for that use
