The procedure involved is very simple:
1. check that all equipment is safe to use and is not broken in any way, if it is do not use this equipment.
2. make sure both regulator knobs are lose
3. open the acetylene control values.
4. turn the acetylene regulator adjustment knob until the desired reading
5.repet steps 3 an 4 but with oxygen.
6. open the acetylene blowpipe pipe (about half turn)
7.with a flint light, point the tip into the catchment area of the lighter.
8.adjust the acetylene blowpipe valve until a flicker of sut is coming from the flame
9. open the oxygen blowpipe valve until there is a neutral flame ( a neutral flame should have a small cone near the tip.

What are the three types of acetylene welding flames?
Mixing Acetylene and Oxygen in the correct proportions produces an extremely hot flame. Using just enough Oxygen so that the Acetylene is almost completely consumed in the flame is called a Neutral Flame. In most welding and cutting applications you would utilize this flame. Reducing the amount of Oxygen produces a Carburizing Flame. It is yellowish and not as hot as a Neutral Flame, but, is used in certain situations. Welding Aluminum is one. Increasing the Oxygen produces an Oxidizing Flame. It produces a flame that is pointed, colder, and louder than a Neutral Flame. It wastes fuel and isn't as efficient as a Neutral Flame.
What types of flame are obtained in oxy-acetylene gas welding?
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
How does adjusting the needle valve on the Bunsen burner affect the flame?
The needle valve or flow valve controls the flow of gas into the Bunsen Burner.
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.
Explain A charge insulator can be discharge by passing it just above a flame?
A charged insulator can be discharged by passing it just above a flame because a flame has a cloud of ions above it. Even though the overall charge above the flame is neutral, a charged insulator will use up the ions that it needs and neutralize.
