e. Do not weld or cut on materials having a combustible coating or
combustible internal structure, as in walls or ceilings, without an
approved method for eliminating the hazard.
f. Do not dispose of hot slag in containers holding combustible materials. Keep
a fire extinguisher nearby and know how to use it.
g. After welding or cutting, make a thorough examination for evidence of
fire. Be aware that easily visible smoke or flame may not be present for
some time after the fire has started. Do not weld or cut in atmospheres
containing
h. Dangerously reactive or flammable gases, vapors, liquids, and dust.
i. Provide adequate ventilation in work areas to prevent accumulation of
flammable gases, vapors, and dust. Do not apply heat to a container that
has held an unknown substance or a combustible material whose contents,
when heated, can produce flammable or explosive vapors. Clean and purge
containers before applying heat. Vent closed containers., including castings,
before preheating, welding, or cutting.
WARNING!
INHALATION HAZARD:
Welding Produce TOXIC FUMES.
Exposure to welding exhaust fumes can increase the risk of deve-
loping certain cancers, such as cancer of the larynx and lung can-
cer. Also, some diseases that may be linked to exposure to welding
exhaust fumes are:
a. Early onset of Parkinson's Disease
b. Heart disease
c. Ulcers
d. Damage to the reproductive organs
e. Inflammation of the small intestine or stomach
f. Kidney damage
g. Respiratory diseases such as emphysema, bronchitis, or pneumonia
Use natural or forced air ventilation and wear a respirator approved by NIOSH to
protect against the fumes produced to reduce the risk of developing the above illnes-
ses.

9. Avoid overexposure to fumes and gases. Always keep your head out of the fumes.
Do not breathe the fumes. Use enough ventilation or exhaust, or both, to keep
fumes and gases from your breathing zone and general area.
• Where ventilation is questionable, have a qualified technician take an air
sampling to determine the need for corrective measures. Use mechanical
ventilation to improve air quality. If engineering controls are not feasible, use
an approved respirator.
• Work in a confined area only if it is well ventilated, or while wearing an
air-supplied respirator.
• Follow OSHA guidelines for Permissible Exposure Limits (PEL's) for various
fumes and gases.
• Follow the American Conference of Governmental Industrial Hygienists
recommendations for 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 specific
welding or cutting situation.
10. Always keep hoses away from welding/cutting spot. Examine all
hoses and cables for cuts, burns, or worn areas before each use. If any damaged
areas are found, replace the hoses or cables immediately.
11. Read and understand all instructions and safety precautions as
outlined in the manufacturer's Manual for the material you will
weld or cut.
12. Proper cylinder care. Secure cylinders to a cart, wall, or post, to prevent
them from falling. All cylinders should be used and stored in an upright position.
Never drop or strike a cylinder. Do not use cylinders that have been dented. Cy-
linder caps should be used when moving or storing cylinders. Empty cylinders
should be kept in specified areas and clearly marked "empty."
13. Never use oil or grease on any inlet connector, outlet connector,
or cylinder valves.
14. Use only supplied Torch on this Welder. Using
components from other systems may cause personal injury and damage
components within.
15. People with pacemakers should consult their physician(s) before using this
product. Electromagnetic fields in close proximity to a heart pacemaker could
cause interference to, or failure of the pacemaker.
