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:
• Early onset of Parkinson’s Disease
• Heart disease • Ulcers
• Damage to the reproductive organs
• Inflammation of the small intestine or
stomach • Kidney damage
• 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
illnesses.
10. O.*4V%2&(%9,5,3*9%/,($#1%%Before using any
helmet, any part that appears damaged should be
carefully checked to determine that it will operate
properly and perform its intended function. Check
for alignment and binding of moving parts; any
broken parts or mounting fixtures; and any other
condition that may affect proper operation. Any
part that is damaged should be properly repaired
or replaced by a qualified technician. Do not use
the helmet if any switch does not operate properly.

15. Maintain the helmet and lens correctly
to help ensure reliable protection:
a. Clean filter’s surfaces regularly. Keep sensors
and solar cells clean using a clean lint-
free tissue/cloth. Do not use any solvents
on filter’s screen or helmet components.
Protect filter from liquid and dirt contact.
Do not immerse the filter in water.
b. Should the Auto-Darkening Welding Helmet
not darken upon striking an arc, stop
welding immediately and have the helmet
checked by a qualified service technician.
c. Regularly replace the Front Lens Cover
if it becomes cracked, scratched,
pitted, or otherwise damaged.
d. Do not make any modifications to either the
Auto-Darkening Filter or the rest of the helmet,
other than those specified in this manual. Do
not use any replacement parts other than
those specified in this manual. Unauthorized
modifications and replacement parts will
void the warranty and expose the user to
the risk of personal injury. Do not open or
tamper with the Auto-Darkening Filter.
16. Do not place the Welding Helmet’s Auto-
Darkening Filter on a hot surface.

a As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which
gives sufficient view of the weld zone without going below the minimum. In oxyfuel gas welding, cutting, or
brazing where the torch and/or the flux produces a high yellow light, it is desirable to use a filter lens that
absorbs the yellow or sodium line of the visible light spectrum.
