Product description:
The welding helmet with an automatic welding fi lter is a Category II eye and face protection designed for individual
protection of the eyes and face against mechanical and light hazards. The helmet has increased mechanical resistance. It does not protect
against drops and splashes of liquids, 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 retaining headband allowing the helmet to be worn on the head made of polyethylene and helmet
lining made of PU foam. The welding fi lter protects the eyes against radiation generated by electric arc welding and has two darkening
states 3 for a light state and 11 for dark state. 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 accord-
ance with the instructions in the manual.

Instructions for use:
Before fi rst use, remove the protective fi lm from the protective glass panel. Leaving the fi lm on reduces the transpar-
ency and aff ects the operation of the welding fi lter. To remove the protective fi lm it may be necessary to disassembly the fi lter and/or the
protective glass panels described further in the manual. Replace worn and damaged components only with original parts. 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. One part of the strap has a knob, which should be pressed into the hole in the other part of
the strap. This will prevent unintentional change in strap length. Press the knob at the back of the headband strap, and twist it to adjust the
length of the strap so that it is not too tight when it is in use, while staying in place when the head is moved. Use the side knobs to adjust
the force needed to lower and lift the helmet. By loosening the knobs it is possible to adjust the distance from the helmet to the face. The
regulation consists in loosening both knobs, then moving the helmet backwards or forwards and tightening the knobs. Make sure that both
knobs are set in the same position (II). Above the knobs, on the right side of the strap there are pins for adjusting the angle of the forehead
shield at maximum lowering and lifting. To adjust, move the cam that is between the strap and the helmet so that the opening in the cam is
placed on one of the pins (III).
The operation of the automatic welding fi lter:
The fi lter does not require any adjustment. As soon as welding light is detected by the
sensors, the fi lter will change the degree of darkening.
Replacement of the batteries:
The battery is located inside the fi lter housing. Remove the fi lter and separate the two parts of the fi lter
housing by levering them at the notch (IV). Slide the battery out of the contacts and then insert a new one.
Replacement of the protective glasses:
If scratches, cracks, clouding or other damage to the protective glasses are observed, they must
be replaced with new ones. In order to replace the glass panels, the fi lter should be removed from the helmet as well as from its mounting
frame. To remove the fi lter, move both locks inwards (V) and then remove the fi lter frame. Carefully pull out the upper and lower edges of the
frame and remove the fi lter from the frame. The front protective glass panel is mounted directly in the helmet (VI). The rear protective glass
panel is mounted in the helmet shell. Lift the glass panel in the middle of the edge at the notch in the shell and then pull it out of the shell
handles (VII). Lightly bend the new panel and then insert the side edges into the handles of the helmet shell (VIII). Caution! It is forbidden
to use the helmet without protective glass panels.
Replacement of the welding fi lter:
Remove the fi lter and install a new one in its place. Make sure that new batteries are installed in the
new fi lter.
Working with the welding helmet:
The fi lter installed in the helmet shell will work automatically if it is illuminated by the electric arc gener-
ated during welding. The response time is 1/25,000 seconds. Before welding, make sure that the knob is set to the dark state appropriate
for the type of welding to be performed. If during operation you notice that the fi lter is not automatically darkening, stop working immediately
and adjust the fi lter. If, despite adjustment, the fi lter does not function properly, contact an authorised service centre of the importer. It is
forbidden to work with a non-functioning welding fi lter, which can lead to irrecoverable damage to the eyesight. Temperature range of the
working environment is from -5
o
C to +55
o
C. The fi lter is not designed to protect the eyesight during laser welding.
Operating instructions
: Filter sensors should be kept clean and not obscured. In the automatic welding fi lter with manual adjustment, the
maximum and minimum degree of protection is when the adjustment is set to zero. Eye protection against high-speed particles, worn in
conjunction with standard corrective glasses, can transmit the impact, posing risk to the user.
Caution! If high-speed particle impact protection is required at extreme temperatures, the selected eye protection device should be marked
with the letter T immediately after the letter identifying the impact symbol, i.e. FT, BT or AT. If the letter indicating the impact symbol is not
directly in front of the letter T, then the eye protection can only be used to protect against high-speed particles at room temperature.
Maintenance and storage:
After fi nishing work, clean the helmet with a soft and damp cloth. Larger instances of soil should be removed
with soapy water and dried with a cloth. Do not use abrasive cleaning agents. Do not use solvents to clean the fi lter and the helmet. Do not
immerse the welding fi lter in water. The product should be stored in supplied unit packaging in a dark, dry, ventilated and closed room. During
