Refilled tank pressures

[Mark @ Everlast]

Oxygen,
Fortunately for my size cylinders, I can use nearly 2 cylinders of O2 (300+) for every one 80-90 Acetylene. Works out good that way. This also includes a little welding and brazing time.

I was swapping out my small oxy tanks one day at the local Norco and when I grabbed the new tank I told the guy it wasn't full. He told me you can't tell the difference between the weight of a full tank and an empty one. I said 'Oh really, oxygen doesn't weigh anything?' he put a gauge on it and it was only half full

Good for you....it absolutely does have weight. when I ran the dive shop, I could always tell the full tanks from the empty ones in a heart beat.
