The shop I rent isn't heated 24/7, only get to run a LP heater while I'm working basically just to take the bite out of the air. But I'm wondering what effects the cold, especially at night, will have on the shielding gas mix (argon/CO2)? Would one gas become heavier than the other and cause a screwed up mix or something along those lines?

I never thought of it but i have been doing some welding in a non heated shop and in certain conditions I get alot of poriosity when I dont think I should.
