Description:
The
liquid crystal light valve in this product can turn from light to dark
at the moment of electricity arc appearing, with the principle of
photoelectric. The darkness degree can be adjusted between DIN 9 and 13.
UV-IR filtering assembly consists of reflective coated glass,
multi-layer light valve and polarizer. It can effectively block the
ultraviolet radiation and infrared ray, and effectively protect workers'
eyes against the damage from ultraviolet radiation and infrared ray.
Features:
Automatic
darkening helmet has wider coverage than common helmet.
It can be used
to protect the face and neck against damage from electricity arc and
improve working efficiency.
This product is widely used in shipbuilding, petroleum, architecture, steel, boiler manufacture and so on.
The
helmet can converse the electricity arc resulted from welding to
electronic signals. These signals will be magnified and passed to the
LCD driven circuit, in which the light valve will be turned from light
to dark.
It
can effectively block the ultraviolet radiation and infrared ray, and
effectively protect workers' eyes against the damage from ultraviolet
radiation and infrared ray.

Instruction:
(1)
Open the package and take out the helmet. Tear off the protective film
on the viewing area. Check whether every part is undamaged (the lithium
battery is installed before delivery).
(2)
Adjust tightness of the comfort cushion through the manual knob in
order to make the user comfortable after wearing it. It adopts
self-locking function design. Press the headband button for an elastic
adjustment. PICTURE:2
(3)
Adjust the knobs on the sides of the helmet to change tightness when
lifting the helmet up and down. Visual angle can be moved forward or
backward as you need. PICTURE:3,4
(4)
Adjustable sensitivity and delay time of the viewing area according to
different working condition. Reduce the sensitivity to avoid
interference. When small current low arc is used, high sensitivity can
be selected. But high sensitivity must be adopted in case of argon arc.
Delay time is the time when filter turns from dark to light.
