How to do oxyhydrogen flame adjustment

Generally,the oxyhydrogen flame is straight and concentrated as for free carbon element,and the flame temperature is as high as 2800 degree.Sometimes,we can see that oxyhydrogen flame have two layers of flame.The innermost flame is the bluest and brightest, and the outermost flame is divergent.The kind of flame is suitable for welding and heating large area and lower temperature requirements for welding parts. How does the oxyhydrogen flame adjust?

There is a kind of carbonated liquid also named cooling liquid which is easy to vaporize. The chemical name of carbonated liquid is Alcohol (ethyl alcohol), methyl alcohol, acetone, petroleum ether.When oxygen hydrogen gas is mixed with carbonated liquid for combustion,it will reduce the hho flame temperature.The more oxygen hydrogen gases enter into auxiliary tank,the more carbonated liquids are vaporized,and the more oxyhydrogen flame temperature drops down.Methyl alcohol is the most common economy chemical liquid.However, petroleum ether is the best choice for some applications like jewelry welding where the flame temperature is very low.

How to add the carbonated liquid into additive tank?
1)counter-clockwise direction(left twist) to screw the additive tank.
2)Use the funnel to add the cooling liquid to the tank, and not exceed the 1/3 of the tank.
3)Clockwise direction(right twist) to tighten the additive tank.

If the oxyhydrogen flame is yellow,maybe the cooling additive is too much, or flame torch nozzle is dirty.Just pour out the excess cooling additive,or clean and poke the fire nozzle with small needle.

There are two kind of additive tank in the Okay Energy oxyhydrogen generators.The OH100-OH1000 oxyhydrogen generators have the additive tank.The OH2000-OH20000 oxyhydrogen generators have independent additive thank shaping like red cylinder.
