gas quality
(OP)
High pressure gas bottles have to be tested every 10 or so years. The test date has to be stamped into the bottle. I'm getting bottles from some gas suppliers that have dates from the 1930's, some even older. My experience in general is when using bottles this old the laser does not seem to have good stability. Of course the gas suppliers say it doesn't matter. I'm seeing this mostly with the CO2 bottles.
Lasers that use higher currents seem most sensitive to this. I'm also noticing a milky buildup on the optics when using these old bottles.
Is anyone else noticing anything like this?

RE: gas quality
and the oldest is 1998 !!
I haven't notice this kind of problems maybe because our customers are not provided with old bottles by gas suppliers.
I hope you will understand what I say because I'm not really good in english LOL
