Note :
Oxygen consumption is roughly:
- 1.1 times that of acetylene
- 4 times that of propane
- 2 times that o fnatural gas
- 2.5 times of that MAPP
At no time should the withdrawal rate from an acetylene cylinder exceed 1/7 of the cylinder's content per hour. Cylinder should be manifolded if this rate is exceeded.
* Gas pressures shown are for 25 feet of 1/4 inch diameter hose. For different hose lenghts and/or diameters consult pressure drop tables.
