How do i control the height of the burner flame?
You can make the flame hotter by first, lowering the flame from the starting point by slowly closing the gas valve until the flame is at a medium height. Then, you should increase the oxygen intake by slowly opening the oxygen valve until you have a completely non-luminous flame (an all-blue flame), which is hotter than an orange or yellow flame.
