IMPORTANT SAFETY INSTRUCTIONS
DANGER. If, at any time, the face plate
in the cartridge fails to darken when
exposed to a welding spark, DO NOT
USE.
Remove cartridge and return to your dealer for
checking. Continued use of the product knowing
that the auto darkening feature is not functioning
may damage your eyes and cause blindness.
Continued use of the helmet which is not
functioning will invalidate the warranty and could
prohibit a successful claim on any insurance
company.
Never carry out repairs on or modifications to the
welding helmet. These may only be carried out by
trained experts.
