Notes:
1. Inlet pressures off all pressure torches
2. Minimum purity of oxygen: 99.7%
3. Depends on the surface condition of the steel plate (specification and
paint) regardless of increased or decreased pressure of fuel oil and gas or
cutting speed. Besides, all data shall be adjusted when precision cutting is
required.
