resistant screens. Use a re resistant
material to block all openings and protect
combustible walls, ceilings, oors, etc.
5. If working near/on a metal wall, ceiling, oor, etc.,
prevent ignition of combustibles on the other side
by moving the combustibles to a safe location.
If relocation of combustibles is NOT possible,
designate someone to act as a re watch equipped
with a re extinguisher during the welding or
cutting process and for at least one half hour after
the welding or cutting project is completed.
6. Do not place the Torch on any material other than
bare concrete until it has cooled completely.

present for some time after a re has started.
11. Do not weld or cut in atmospheres
containing dangerously reactive or
ammable gases, vapors, liquids, or dust.
12. Clean and purge containers before applying heat.
Do not apply heat to a container that has held an
unknown substance or a combustible material whose
contents, when heated, can produce ammable or
explosive vapors. Vent closed containers, including
castings, before preheating, welding, or cutting.
Personal Safety
1. Wearing and using personal safety
clothing and safety devices reduce the
risk of injury. Wear the following:
a. Fire-resistant clothing (Do not wear pants with
cuffs, shirts with open pockets, or any clothing
that can catch and hold molten metal or sparks.)
b. Fire-resistant leather leggings and work boots
c. Dry, insulating leather welding gloves
d. NIOSH-approved respirator
e. Shade 5 or higher welding goggles
f. Appropriate head covering to
protect head and neck
g. Fire-resistant ear plugs or ear muffs (if welding
or cutting overhead or in conned spaces)
Keep clothing and safety equipment free of grease,
oil, solvents and any other ammable substances.
2. Stay alert. Watch what you are doing, and
use common sense when operating this
Torch. Do not use while tired or under the
inuence of drugs, alcohol, or medication.
A moment of inattention while operating
may result in serious personal injury.
5. Avoid overexposure to fumes and gases. Keep
your head out of the fumes. Do not breathe fumes.
Use enough ventilation or exhaust, or both to keep
fumes and gases away from your breathing area.
Where ventilation is questionable, have a qualied
technician take an air sampling to determine the
need for corrective measures. If necessary, use
mechanical ventilation to improve air quality. If this
is not possible, use an approved respirator. Do not
work in conned areas unless they are well-ventilated
or you are wearing an air supplied ventilator.
Always follow OSHA guidelines for Permissible
Exposure Limits (PEL’s) for various fumes and gases.
Follow the American Conference of Governmental
Industrial Hygienists recommendations for the
Threshold Limit Values (TLV’s) for fumes and
gases. Have a recognized specialist in Industrial
Hygiene or Environmental Services check the
operation and air quality and make recommendations
for the specic welding or cutting situation.

Cylinder Safety
Operation Safety
1. Do not use dented or damaged cylinders.
2. Secure cylinders to a cart, wall, or post to prevent
them from falling.
Use and store cylinders in an upright position only.
If using the included case to hold the cylinders,
secure the case to a cart, wall or post.
3. Use cylinder caps when moving
or storing cylinders.
4. Do not store cylinders in
temperatures 120° F or higher.
5. EMPTY CYLINDERS:
DO NOT DROP, STRIKE, PUNCTURE, HEAT OR
SET FIRE TO A CYLINDER, EVEN IF IT IS EMPTY.
Keep empty cylinders in specied areas and
clearly mark “empty”. Contact local solid
waste authorities for instructions on correct
disposal or recycling of empty cylinders.
6. KEEP WRENCH ON
ACETYLENE CYLINDER’S VALVE
whenever cylinder is in use to allow
quick shutoff in case of emergency.
Equipment Inspection
1. DO NOT USE FLAME TO DETECT LEAKS.
2. INSPECT BEFORE EVERY USE.
Look for the following, and do not
use kit if any damage is noted:
a. Inspect the tapered seating surfaces on the
Nozzles, and the Tip Nut. Have a qualied
technician resurface the seat area if it has
dents, burrs, or is burned. A poor seating
surface may result in backre or ashback.
b. Examine all hoses for cuts, cracks,
burns, worn areas, or other damage.
Do not use if damaged.
c. Check for loose connections using soapy
water solution. Tighten or repair any leaks found.
d. Do not use the Torch Kit if either
gas does not turn off completely
when the Oxygen Torch Valve and
Acetylene Torch Valve are closed. Leakage
of gas from the tip is a substantial safety risk.
If gas cannot be turned off at the Torch Handle,
it is dangerous and must be replaced.
e. Inspect for any other defects or damage.
Do not use any damaged parts.
Tag damaged parts “Do not use” until repaired.
1. Inspect before every use,
see previous warning section.
2. Use only with proper ventilation.
3. Do not touch workpiece or tip until cool.
4. Keep hoses away from hot parts,
from cut area, and from ame.
5. Never leave the Torch unattended when
it is attached to a gas supply.
6. Allow sufcient time for the Torch to
completely cool before storing.
7. Any material discharged from the work area
during use will be extremely hot. Use care to
not get burned by slag or other waste products.
8. BACKFIRE:
When the ame goes out with a loud “pop”, it is
called a backre. Backre can be caused by:
a. Operating the Torch at lower pressures
than required for the Tip used.
b. Touching the Tip against the workpiece.
c. Overheating the Tip.
d. An obstruction in the Tip.
If backre occurs, close the Torch Handle Valves
(oxygen rst, then acetylene) and after
remedying the cause, relight the torch.
9. FLASHBACK:
Flashback is a condition that results when the ame
ashes back into the Torch and burns inside with a
shrill hissing or squealing noise.
If ashback occurs, close the
Torch Handle Valves (oxygen rst, then acetylene)
IMMEDIATELY! Flashback generally indicates a
problem that should be repaired before proceeding
with the job at hand. A clogged Tip, improper
functioning of the Valves, or incorrect acetylene/
oxygen pressure could lead to ashback. Find and
correct the cause before relighting the Torch.
If the cause is not found, have the kit serviced by a
qualied technician before returning to your project.

10. Beware of leaking gas. If while you are using
this Torch you notice the odor of acetylene,
IMMEDIATELY close the oxygen rst,
then the acetylene.
Extinguish all open ames and carefully check all
hoses and connections for leaks using soapy water.
NEVER check for leaks using a ame.
If the odor continues do not use the Torch.
Call acetylene supplier for assistance.
11. Read and understand all instructions and safety
precautions as outlined in the manufacturer’s
manual for the material you will weld or cut.
