Global Warming: Investment Implications [View article]
however helium is lighter than air so its blanketing capability is not too great.
for many yrs i've done TIG welding (some people call it MIG) using an argon bottle for blanketing. A40 is denser than air.
not once have i used a CO2 bottle. CO2 is an oxidizer @ high temperatures, reacts with some metals. last thing you want in your workshop is carbon monoxide.
