2. Proper Storage
The system should be
stored in the ready for
service position. This
means the following
should be paid attention
to.
• Fuel canister is full of
Camp Fuel
• O2 bottle is full and
the regulator is
seated properly with
O-ring.
• The fuel hose has
been purged prior to
storage.
• Accessories are
stored inside of unit.
3. Torch Position
• Ensure the torch is
stored with the
cutting tip down.
This will eliminate
the chance of the
connections getting
plugged with debris.
4. Striker Tool
• Ensure that the
striker tool is ready
for service.
• If the flint is worn,
loosen the screw
and rotate the flint
plate to the next flint.
5. Proper PPE
Ensure that the person
cutting is wearing the
following-
• Gloves
• Torch Glasses
• Arm and Leg
Protection
6. Lighting the
Torch
Follow these steps in
order for the best
results.
1. Turn on the O2 ½
turn.
2. Add fuel slowly until
a fuel mist is seen.
3. Create a spark with
the striker. Be
careful not to
saturate the striker.
4. After lite, adjust the
flame by adding or
reducing the fuel.
This picture shows a
flame that is too rich (too
much fuel).
8. Perfect Flame
The perfect cutting flame
should be mostly blue
with a very short amount
of white near the cutting
tip.
This flame will make a
jet noise.
Be careful not to add too
much O2. This will only
deplete our resources
quickly and not help the
cutting process.
9. Starting a Cut
To start cutting, hold the
torch close to, but not
on, the object being cut.
Once the metal
becomes molten, slowly
squeeze the handle on
the torch.
Squeezing the handle
adds more O2, thus
increasing the flame’s
temperature.
10. Hand Position
Proper hand position will
help make a consistent
cut.
One hand squeezes the
handle, while the other
steadies the tip close to
the object being cut.
11. Good Hand
Position
This is a great example
of using the lead hand to
keep the tip at the
proper distance.
12. Hand Position
This techniques is
difficult to keep the tip at
a constant distance from
the object. Although not
ideal, it made be
necessary to cut in this
position.
13. Cutting
I-Beams
It is possible to cut
several inches into thick
steel with the Petrogen
Torch.
Practice cutting through
the web while cutting the
top or bottom of an
I-Beam.
14. Cutting
I-Beams
It is helpful to slightly
angle the cutting tip in
the direction that you are
cutting.
This technique helps
keep the molten slag
from melting back
together after your pass.
15. Cutting Rebar
If you have someone
impaled on rebar, then
you should consider
using this technique.
• Wrap the rebar with
a towel saturated in
water next to the
patient.
• The wet towel will
absorb the heat
being transferred
along the rebar.
• Notice the bare hand
holding the rebar.
With the wet towel,
no heat is felt on the
other side.
16. Cutting Fence
Post
A fence post can be cut
in the same fashion as
rebar.
Again, with a saturated
towel, no heat is
transferred to the
patient.
17. Fence Post
This object can be cut
with one pass. This
reduces that amount of
cutting time and the
amount of heat
generated.
18. Hollow Posts
A post that is hollow
does transfer heat, even
with the use of a wet
towel.
The hollow chamber
allows the heat to
quickly spread.
DO NOT use a torch to
cut this object if it is
impaled in a patient.
19. Hollow Post
This object can also be
cut with one single pass
if the cutting tip is held in
a consistent position.
