What is the initial oxygen pressure provided through the lance? Correct Answer 1 atm to 2 atm

In oxygen lance cutting, jet of oxygen is passed through steel pipes, and by doing this, holes are produced. For doing this, the jet of oxygen is passed through the lancer under the pressure of 1 atm to 2 atm.
