Oxy hydrogen flame is a mixture of hydrogen and oxygen gases.
It is obtained by either electrolysis or combustion.
It is characterized by a very high temperature.
Since both gases are combustible, it increases combustion.
Hydrogen gas readily burns in oxygen or air along with the formation of water. This is called combustion of Hydrogen or direct oxidation of Hydrogen gas.
The flame produced is neutral and it increases temperature.
The flame has a temperature of around 2800 degree Celsius.
At this temperature, metal tends to melt very easily. Therefore, it is generally used for cutting and melting metal.
