--Speaking of gasses the last time Ernie came a-calling he pointedout that my "argon" tank was, in fact, full of CO2. He could tell by the waythe arc was struck, but I couldn't see it. Can someone suggest a method thatwould allow mere mortals to tell these two gasses apart? I'm wondering ifbubbling it thru some common liquid might make a distinctive change or somesuch..

Well, you may be able to tell if it's CO2 that way; CO2 is soluble in water and will produce a mild acid which you could check for with pH indicator strips.Argon is inert so very difficult to test other than by an electrical discharge at reduced pressure where it has a lilac glow.Martin

If it doesn't work, it is argon or something else.
