Argon \Ar"gon\, n. [NL., fr. Gr. ?, neut. of ? inactive; ? priv.
? work.] (Chem.)
A colorless, odorless gas occurring in the air (of which it
constitutes 0.93 per cent by volume), in volcanic gases,
etc.; -- so named on account of its inertness by Rayleigh and
Ramsay, who prepared and examined it in 1894-95. Symbol, A;
at. wt., 39.9. Argon is condensible to a colorless liquid
boiling at -186.1[deg] C. and to a solid melting at
-189.6[deg] C. It has a characteristic spectrum. No compounds
of it are known, but there is physical evidence that its
molecule is monatomic. Weight of one liter at 0[deg] C. and
760 mm., 1.7828 g.

I have recently set both regulators to 35psi My argon regulator was set to 50psi but some times it likes to creep up to 65 or 70 psi, that's no good To avoid this I turned the argon down to 35psi, it hardly creeps at all at that pressure, then did the same for the CO2
