How to adjust the preheating flame of gas cutting

Adjust the size of preheating flame according to the thickness of the object, and accurately use the pressure of oxygen according to the thickness of the object.

If oxygen is not turned on, only acetylene is turned on, the burning flame will be red, black smoke will be emitted, and black filamentous substances will float out. If oxygen is not fully turned on (or the proportion of mixed gas is incorrect), the burning flame will turn yellow for a long time, and a small amount of carbon deposit will block the outlet of preheated oxygen.
