You may be having tank "size" problems---The tank is first filled with a
media, then filled with acetone, then the acetylene is pumped in slowly, it
takes time for it to dissolve into the acetone--about 10 or 12 hours as I
The reverse is true also, it takes time to withdraw it---you can't run a
a 50 cu.ft. tank---at least not very long.. also cold weather may have an
on the available pressure, especially after starting to use some.---I seem to
remember seeing 150 psi or so on a full tank.
In summer on a new bottle I think it was about 250 psi. Now winter and
virtually empty its only just registering on the gauge down around 10psi
but still working a 10 tip. About time to change it though. I never use
anything that big in the way of a torch so am not to demanding.

Well I do understand not to draw too fast the acetylene or the acetone
will come out. It is correct if I reasone that acetylene can be drawn down
to 25 psi if I respect the 1/7 rule? BTW, 1/7 tank capacity means 1/7 of
total capacity or 1/7 of the capacity left in the tank?
