4.
Close the oxygen valve first, then the MAPP valve, when the job is
complete. Allow the torch to flame out.
5.
Place the hot torch on a surface that can handle the heat and allow it
to cool.
6.
Once the torch has cooled, unscrew the cylinders from each valve and
place the cylinder cap on them.
7.
Place the torch and the cylinders in storage. Consult each cylinder's
instructions on how to properly store them.
REFINING THE FLAME
Once oxygen is introduced, the colour will change from yellow to blue and the
outer flame length will be between 4 and 6 inches, with an inner flame length of
approximately 1/2 in. Further adjustments are possible to create a flame suitable
for different purposes.
SOLDERING OR HEAT TREATING
Increase the amount of MAPP gas supplied to the torch. The outer flame will be
yellow with a length of 7 to 9 inches. The inner flame may not form. The heat
generate is approximately 750ºF (400ºC).
WELDING OR BRAZING
Establish a soldering flame. Increase the flow of oxygen until a 1/2 in.
blue flame forms at the burner tip. A full oxygen cylinder will last approx.
20 to 25 minutes.
CUTTING FLAME
Establish a welding flame. Adjust the flow of both the MAPP and oxygen
gas until the blue flame is only 1/4 in. at the burner tip within a 5 in. long
yellow flame.
Heat the metal workpiece, then turn off the MAPP gas. Cut the metal using only
the oxygen. Should the flame be extinguished before the cut is complete, turn
off both gases and repeat the steps to create the cutting flame.
A full oxygen cylinder will last approx. 7 to 12 minutes.
