SECTION 2 – INTRODUCTION
Arc welding without protective equipment is dangerous and can lead to painful inflammation of the
cornea and irreversible clouding of the eye lens (cataracts). The PUK-SM with its integrated LCD –
welder view protection filter offers reliable protection against these dangers and
permanently protects
against UV/IR rays, sparks and splashes at both light and dark levels. The filter’s protection levels are
defined to avoid blinding from arc welding. The PUK-SM should only be used for welding if the LCD
welder view protection filter is mounted and only together when using a PUK spot welding device.
Shortly prior to lighting an arc, the electronic component of the PUK spot welding device switches the
filter from the DIN 3 level to the safer DIN 11 dark level. As soon as the arc is turned off, the filter is
switched back to the light setting.
