Reduction Neutral Oxidizing Flames-Where R

[orodrago]

Hi All,
Sorry for this typical newbie question - but hope someone can clear this up for me, pretty please?
I read about Reduction, Neutral and Oxidizing Flames - and I would like to know where are each of these areas in my torchs flame?
I would assume that Oxidizing is way up the top - where there would be very little air left in the flame? So, would Neutral be in the middle somewhere?
IF, (big IF) thats right - then to get a reduction effect, Id need to work very low in the flame?
Thanks everyone for your patience! Even a pointer to a tutorial or FAQ page would be of great help.
Stay safe!

Actually its the way your torches fuel/oxygen ratio is adjusted.

If you have a "surface mix" torch ...

A "oxidizing flame" is a flame that is rich in oxygen and poor in fuel.... Will burn cool and probably have a little bit of hissing... The candles at the base of flame will probable have very little yellow in it and actually flame may stand off face of torch just a bit. Actual flame will probable be light blue.

A "neutral flame" is the correct mix of oxygen and fuel. It will probably be a nice medium blue and the candles will be blue with about the last 1/4 being a yellow-white in color.

A "reducing flame" is a fuel rich, oxygen poor flame. Usually yellow-orange in color through out complete flame. Candles at face of torch will contain very little blue flame (mostly yellow-orange).
