1, prepare tools and materials, oxygen bottles, acetylene bottles, gas cutting guns, wire brushes, frosted paper, liquid paraffin, etc.

2, check the purity and pressure of oxygen and acetylene, oxygen and acetylene purity should be not less than 99.5%, oxygen pressure should be 20MPa, acetylene pressure should be 0.5MPa.

3, open the oxygen valve, adjust the flame, make the flame blue and no noise, open the acetylene valve, adjust the flame, make the flame light blue, you can start cutting metal.
