tank storage

The pressure in tanks of compressed gasses like Nitrogen and Oxygen will drop. Not an issue for welding since the gas will come out at the same pressure after the regulator. It can be a minor problem at the end of the tank, you can't get quite as much gas out of the tank.

Acetelyne is another story, it is dissolved in acetone, the rate of coming out of solution is very temperature dependent. You can't pull any where near the same discharge rate from a cold tank as from a warm one.

That said, a lot of us have tanks that sit out, mine get as cold as 0 F. You may have to tweak a regulator adjustment to get the perfect weld.

RoyJ gave you an actual answer.

Personally, I don't like getting out there to weld when it is that cold! I'll wait for a warmer day. When the day is warmer, the bottles are ok, too. They should be fine just sitting out in the cold, cold weather - unlike me.

That doesn't sound like fun. I rather hate the cold myself, but when I have a welding project in the winter I find it helps warm up the shop. All that heat has to go somewhere after all.

Thanks for the help, again. I'll probably have more questions after Christmas when I complete my basic setup. You and the rest of this list have been an invaluable source of information.
