SETUp
5. Open the Acetylene Torch Valve about 1/4 turn,
and quickly ignite the acetylene gas
coming out of the Nozzle by squeezing the
handle of the striker, creating a spark.
WARNINg!
Do not use matches or a
butane lighter to light the Torch.

6. Put the striker down on a fireproof surface.
Slowly open the Acetylene Torch Valve
farther until the flame feathers at its
edge slightly, as shown below.

Flame Adjustment:
a. Starting to Add Oxygen:
Slowly open the Oxygen Torch Valve.
The flame will change to a carbonizing flame with
a blue/white inner core, a white halo surrounding
the core and a light orange flame as shown
in Welding Step 7 illustration, below left.
b. proper Oxygen Mix:
Continue slowly opening the Oxygen Torch Valve
until the large light orange section of the flame
becomes nearly colorless and the center of the
flame has a white core with little or no halo.
This is the “neutral” flame
needed for operation
as shown in
Welding Step 7 illustration, below center.
c. Too Much Oxygen:
If you open the Oxygen Torch Valve too far, the
large section of the flame will be bluish-orange
and the inner core will be small as shown
in Welding Step 7 illustration, below right.
Close the Oxygen Torch Valve slightly until you
achieve the flame described in step b above.
WARNINg!
Wear appropriate welding goggles.
8. After the flame is adjusted as explained
and illustrated, proceed with welding.
Note:
Oxygen-acetylene welding is a
two-handed process:
one hand controls the torch,
while the other hand controls a filler rod (sold
separately).
Proper welding techniques and weld preparation
are outside the scope of this manual.
Welding books and classes are recommended
to teach proper methods and technique.
9. After welding, follow shutdown
instructions on facing page.
