"low" setting.

USE AND MAINTENANCE

This mask has been designed and manufactured to protect
face and eyes from risks (arc rays and hot metal projections)
associated with welding operations and similar processes: it
must not be used for purposes other than those for which it
has been designed.
When used, it should be kept as close as possible to face and
eyes, and as far as possible from direct heat of the arc.
REPLACE THE FRONT COVER LENS: Replace the front
cover lens if it is damaged (cracked ,scratched, dirty) WM23

involve any danger for the user, but it should be noted that
may cause allergic reactions if it comes into contact with the
skin of particularly sensitive individuals.
