Left over oxygen

I have a portable cutting setup with 10 ft3 tanks of Oxygen and of acetylene. ( I think)
The acetylene pressure is down to about nothing, and I have about 1,000 pounds left in the oxygen tank.
Should I exchange just the acetylene? Or should I just go ahead and exchange the both of them?
I did mainly cutting with what I thought was a neutral flame. Is it normal to burn that much more acetylene than oxygen?
Thanks in advance!

I can't figure out what "10 ft3 tanks of Oxygen and of acetylene." means
?

Tanks are sized by the number of cubic feet of volume they contain.
10 ft3 is the normal way to write ten cubic feet.

I wish I could get a good answer. Are their actually any welders here?

I use a small bottle setup on my work truck. Unless I'm using the cutting head it's not uncommon to go through more than one full bottle of acetylene per oxy tank. I only change them out if my set pressures start to drop.

Thanks Josh. I may try that. With these small bottles I was not sure if it would be worth the trouble. But to save $$$
it's worth checking out.

Depending on where you live the cheapest place to change them out is at a local hvac or refrigeration supply house. They often don't charge a hazmat fee.

How far do you have to go to swap tanks? If its like 10 minutes away, just swap empties.

But 1000 psi is about 1/2 a bottle. No reason to change it out unless it's empty enough to effect your pressure setting on the secondary side.
