INTRODUCTION
Arc welding without protective equipment is dangerous and can lead to a painful
inflammation of the cornea. It can also lead to an irreversible clouding of the eye lenses
(cataract).
The MEZZO with its integrated LCD glare protection filter offers a reliable safeguard
against these dangers. It provides continuous protection against UV/IR-rays, as well as
sparks and splashes, both in the filters clear setting (Luminescence DIN3) as well as in
its dark setting (Obscurity DIN11).
The filter is constructed so that a dazzling from the glare of the electric arc is avoided.
Shortly before an electric arc is fired, the electronic circuitry of the PUK 3s, switches the
filter automatically from its clear setting (Luminescence DIN3) to its dark setting
(Obscurity DIN11). The filter then returns to the clear setting again immediately after the
electric arc is extinguished.
The MEZZO may only be used in conjunction with a PUK precision welding devices.
