Hi! Welcome back. This segment is uniquely devoted to the issue of flame control. Torch
control. And, I am going to light my torch with the striker. Again remember, do not use
a lighter or have that on your surface because of the risk of explosion or fire. In terms
of the sequence of controlling the flame, you want to turn on propane first and oxygen
second. And, in terms of turning the flame off, you want to turn off your oxygen first
and your propane second. That is the safe process or procedure for lighting and extinguishing
your flame. And, it can be remembered by the acronym P.O.O.P. Propane, oxygen, oxygen,
propane. So, propane on first. Oxygen next. And then, turning off. Oxygen. Propane. P.O.O.P.
Got it? Good. Whoa! Ok, propane first, oxygen. Now, in tuning the flame, let us go through
the stages. This is a very carbony, high propane, lot of uncombusted fuel in this flame. And,
glass that is subjected to this flame will not melt as quickly because it is a relatively
cool flame. Oxygen is hotter when you add it up to a certain point and then oxygen can
also cool a flame down. But, a highly propanated flame is relatively cool and is actually great
for dichroic glass, which is a special kind of glass that is shimmery and very rainbowish,
very colorful, highly reflective. And, I am sure you have all seen dichroic can *** up
in a hotter flame but it does pretty well in a fairly rich, cooler, propane-orientated
flame. So, this is a reducing, or highly propanated, flame. Made that word up. Now we are going
to make more oxygen in by opening the oxygen valve. And, you are starting to hear more
of a hiss. These Lynx torches like to have a lot of oxygen so the barrel of the torch
does not get too hot. You can damage these torches by running them too hot.
