b. Remove or make safe all combustible materials for a radius of 35 feet (10
meters) around the work area. Use a fire resistant material to cover or block
all open doorways, windows, cracks, and other openings.
c. Enclose the work area with portable fire resistant screens. Protect combus-
tible walls, ceilings, floors, etc., from sparks and heat with fire resistant covers.
d. If working on a metal wall, ceiling, etc., prevent ignition of combustibles on
the other side by mobbing the combustibles to a safe location. If relocation
of combustibles is not possible, designate someone to serve as a fire watch,
equipped with a fire extinguisher, during the welding process and for at least
one half hour after the welding is completed.
e. Do not weld or cut on materials having a combustible coating or combusti-
ble 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.
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 contai-
ners before applying heat. Vent closed containers., including castings, before
preheating, welding, or cutting.
WARNING
INHALATION HAZARD: WELDING AND PLASMA CUTTING PRODU-
CE TOXIC FUMES.
Exposure to welding or cutting exhaust fumes can increase the risk of developing
certain cancers, such as cancer of the larynx and lung cancer. Also, some diseases that
may be linked to exposure to welding or plasma cutting 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 airsup-
plied respirator.
•
Follow OSHA guidelines for Permissible Exposure Limits (PEL's) for various
fumes and gases.
•
Follow the American Conference of Governmental Industrial Hygienists
re¬commendations 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. Cylinder
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 Inverter Air Plasma Cutter. 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 pro-
duct. Electromagnetic fields in close proximity to a heart pacemaker could cause
interference to, or failure of the pacemaker.
16. USE PROPER EXTENSION CORD. Make sure your extension cord is in good
condition. When using an extension cord, be sure to sue one heavy enough to
carry the current your product will draw. An undersized cord will cause a drop in
line voltage resulting in loss of power and overheating. A 50 foot extension cord
must be at least 12 gauges in diameter, and a 100 foot extension cord must be at
least 10 gauges in diameter. If in doubt, use the next heavier gauge. The smaller
the gauge number, the heavier the cord.
