Product description: The welding helmet with an automatic welding protection fi lter with manual adjustment is a Category II
eye and face protection equipment designed for individual protection of eyes and face against mechanical and light hazards. The
helmet has increased mechanical resistance. It does not protect against liquid drops and splashes, coarse and fi ne dust particles,
gas and arcs caused by electrical short-circuits. The helmet shell is made of PA66 polyamide and fi tted with a headband allowing
the helmet to be worn on the head made of PE and helmet lining made of PE foam. The welding protection fi lter protects the eyes
against radiation generated by electric arc during welding and has a shade level adjustment in the range of 5-13. The fi lter is
protected by a polycarbonate glass panel. Persons allergic to these materials may develop an allergic reaction.
Lifetime: The product does not have a specifi c lifetime. Pay attention to wear and damage of the helmet components. Replace in
accordance with the instructions in the manual.

Operating Instructions
Before fi rst use, remove the protective fi lm from the protective glass panel. Leaving the fi lm on reduces the transparency and
aff ects the operation of the welding protection fi lter. To remove the protective fi lm it may be necessary to disassemble the fi lter
and/or the protective glass panels described further in the manual. Replace worn and damaged components with original parts
only. Do not modify the helmet yourself. It is forbidden to use the helmet if any component shows signs of damage, is worn out
or needs to be replaced.
Adjustment of the helmet support system
Put the helmet on your head, adjust the position of the upper headband strap, if necessary, to make sure the helmet is at the right
height. By turning the knob on the occipital strap, adjust the length of the strap so that it does not press the head while working
and at the same time the helmet does not move during head movements. Use the side knobs to adjust the force needed to lower
and lift the helmet. Pressing the grey fl aps at the fi xing knobs inside the helmet allows you to adjust the distance of the helmet
from the face. When pressure is released, the helmet should lock into one of several positions. Make sure that both sides are set
in the same position. On the inside of the helmet at the left and right knobs, there is an adjustment of the helmet angle at maximum
lowering and raising. Pull the black element (II) and move it relative to the grey one, then lower and lock it in the desired position.
The operation of the automatic welding fi lter
Thanks to the sensors, the fi lter is automatically darkened to the set level when bright light from the welding process is detected.
When choosing the dark state you can refer to the table in the manual showing the recommended protection levels for arc welding.
Darkness level adjustment switch "5 - 8" enables the dark state of the welding fi lter to be set between 5 and 8. "9- 13" - allows you
to set the welding fi lter's dark state between 9 and 13. "5 - 8 Keep on" - allows the fi lter's dark state to be set between 5 and 8. In
this setting there is no bright state and the fi lter is always darkened to the set value. Selection of the fi lter's darkening level in dark
state is made by using the "SHADE" knob. Operating mode switch - deactivates the auto-darkening function and the fi lter remains
bright regardless of external conditions. Before starting work, ensure that the fi lter is set to the correct mode for the type of work
to be carried out. It is forbidden to work with a non-functioning welding protection fi lter, as it can lead to irrecoverable damage to
the eyesight. The fi lter has two additional adjustment knobs. The "DELAY" knob allows you to change the fi lter delay time, which
is the time it takes for the fi lter to respond to the change in light intensity. The adjustment is smooth, with the "F" position meaning
the least delay in darkening of the fi lter and the "S" position meaning the greatest delay in fi lter darkening. The adjustment of the
knob between these settings allows you to select the fi lter response time between the maximum and minimum value.
The "SENSITIVITY" knob allows you to adjust the sensitivity, i.e. the threshold for fi lter operation. The adjustment is smooth,
with the "H" position meaning the highest sensitivity: the fi lter will react to a smaller change in the intensity of the light shining
on the sensors, and the "L" position meaning the lowest sensitivity, the fi lter will react only to a greater change in the intensity of
the light shining on the sensors. For most welding jobs it is recommended to set the knob in the middle of the range. The "LOW
BATTERY" control light allows you to check the state of battery that is powering the welding fi lter. If you press the "TEST" button
and it causes the control light to light up, charge the battery as soon as possible. The welding protection fi lter requires the LIR
2450 3.6 V battery to operate correctly.
