PARTICULAR APPLICATIONS
SOLDERING/HEAT TREATING FLAME
(228.6 mm)
WELDING/BRAZING FLAME
5/16 in.
(7.9 mm)
CUTTING FLAME
1/2 in.
(12.7 mm)
Once the metal is sufficiently heated, and a molten puddle is present, increase the oxygen flow until the molten metal blows
away from the puddle. Move the torch slowly along the cutting line. If the torch is too far from the metal or moves too quickly,
the metal will cool and you will need to restart the cutting process. At this flame setting, a full oxygen cylinder will last
approximately 8 to 12 minutes.
Note: Cutting will generate flying sparks and hot metal drippings, so cut in an area that is away from flammables. Avoid
metal drippings contacting any part of the torch assembly and/or cylinders.

Begin with the starting flame. Then, slowly increase the flow of the fuel by
adjusting the fuel valve (1) so that the yellow portion of the flame remains
in contact with the tip of the torch. Adjust the fuel valve (1) until the flame is
approximately 7 to 9 inches long. If the yellow flame loses contact with the
tip of the torch, reduce the flow of fuel until the flame is touching the tip of
the torch (4).
From the soldering/heat treating flame, slowly increase the flow of oxygen
by adjusting the oxygen valve (2) until there is an inner blue flame ½ inch
long at the tip of the torch. At this flame setting, a full oxygen cylinder will
last approximately 18-25 minutes.
From the welding/brazing flame, slowly increase the flow of fuel by
adjusting the fuel valve (1) until the yellow flame is about 5 inches long.
Then slowly increase the flow of oxygen by adjusting the oxygen valve (2)
until the inner blue flame is about 5/16 inches long. The tip of the inner
blue flame is the hottest and should be in contact with the metal to cut.
