– Set the acetylene outlet pressure to 7psi (but never, ever more than 15). The higher the acetylene pressure, the more unstable and dangerous it becomes. – Set the oxygen pressure to about 15psi.

Never set acetylene pressure over 15 psi — acetylene can become unstable and explode at more than 15 psi. 2. For cutting steel, recommended initial pressure ... cut is initiated, keep the torch ...

Compensate for the pressure drop by increasing the regulator delivery pounds per square inch gauge (PSIG) to ensure back-of-the-torch pressure meets cutting tip requirements. 5. Gauges on the handle – ...
