Rate of acetylene use

Thanks, Stan

Also, I don't think you should rely on the pressure in the cylinder as a measure of how fast you are drawing it down. Just look up the tip you're using on your torch manufacturer's tip chart to see what its flow rate should be.

Another one is not laying the Acetylene tank on its side, if so, it needs to be upright for awhile, like maybe over night, though I play it safe and keep em upright, not sure how that works, but do know enough to respect volatile compressed gases and those tanks.

I've always found that when I need to heat a big chunk of metal with the rosebud, that unless I am at the local college, or another industrial site with the largest bottles, or multiple tanks ganged together, it is going to be a tough go getting enough out of the bottle fast enough.

I agree that it's ultimately about the volume, but the only available means of measuring it are the tank's psi and its weight. I've never heard of anybody weighing the tank as they use the gas, so that leaves only the pressure as measured on the gauge, doesn't it? It makes me wonder if it isn't one of those things where all you can do is to do your best and it either works or it doesn't.

Anybody ever had acetone get into their acetylene regulator that wasn't the result of the bottle being on its side at the time or recently?
