Charging the battery
Only the cable supplied with the product can be used to charge the battery. The cable should be connected to the device's USB
type C charging socket (III) and then to a USB charging socket, e.g. of a computer or in a charger equipped with such a socket.
However, make sure that the current capacity of the charging socket is at least 5 V, 2 A. If the red control light located under the
charging socket is on, it indicates that the charging process is in progress. If the green control light is on, it indicates that the
charging process is completed. The device should be under supervision throughout the charging process. It is not possible to
use the device while the battery is charging. Immediately after charging, disconnect the charging cable from the charger and then
from the device.
WARNING! Leaving the device with a fully charged battery connected to the charger will lead to irreparable damage to
the battery and may cause fi re or electric shock.
Safety instructions for battery charging
Li-ion (lithium-ion) batteries do not have the so-called "memory eff ect", which allows them to be recharged at any time. However,
it is recommended to discharge the battery during normal operation and then charge it to full capacity. If, due to the nature of
work, it is not possible to use the battery in such a manner every time, it should be done at least every several work cycles. Never
discharge any batteries by short-circuiting the battery plates, as this will cause irreparable damage! In addition, do not check the
battery charge status by short-circuiting the electrodes and checking their sparking.
Storing the battery
Ensure proper storage conditions to extend the battery's life. The battery can last for approximately 500 charge-discharge cycles.
Store the battery at a temperature ranging from 0ºC to 30ºC at a relative air humidity of 50%. Charge the battery to approx. 70%
of its total capacity to store it for a longer period of time. In case of prolonged storage, the battery should be periodically charged
once a year. Do not over-discharge the battery as this will shorten its life and may cause irreparable damage. During storage, the
battery will gradually discharge due to leakage. The self-discharge process depends on the storage temperature – the higher the
temperature, the faster the discharge process. If the batteries are stored incorrectly, the electrolyte may leak. In case of leakage,
secure the leak with a neutralising agent. In the case of electrolyte contact with eyes, rinse eyes thoroughly with water, and im-
mediately seek medical attention. It is not allowed to use the tool with a damaged battery. If the battery is completely worn, return
it to a specialist waste disposal centre.
Transporting the batteries
Lithium-ion batteries are treated as hazardous goods according to legal regulations. The user can transport the tool together
with the battery and the batteries alone, by land. In that case, no additional conditions have to be met. If you entrust transport to
third parties (e.g. a courier company), follow the regulations regarding the transport of hazardous goods. Before shipping, please
contact a properly qualifi ed person. It is not allowed to transport damaged batteries. National regulations for the transport of haz-
ardous materials must also be observed.
Replacing the power supply battery
The battery is placed in a housing located on the inside of the welding helmet. Slide the battery socket out of the housing (IV).
Remove the used battery from the socket. Place the new battery in the battery socket according to the terminal markings on the
edge of the socket. Slide the battery socket into the housing. Check the state of charge of the new battery. Charge the battery if it
needs to be charged. Dispose of the used battery safely.
Replacing the protective glass panels
If scratches, cracks, clouding or other damage to the protective glass panels are observed, they must be replaced. To replace the
front protective glass panel, press both lock buttons and hold in this position, then remove the glass panel. The front protective
glass panel is mounted directly in the helmet (V). The rear protective glass panel is mounted in the helmet shell. Lift the glass panel
(VI) in the middle of the edge at the notch in the helmet and then pull it out of the handles. Lightly bend the new glass panel and
then insert the side edges into the handles of the helmet shell. Do not bend the protective glass too strongly to avoid damaging it.
Caution! It is forbidden to use the helmet without protective glass panels.
Replacing the welding protection fi lter
Remove the fi lter by carefully tilting the lower fi lter catches towards the welding helmet until the fi lter (VII) is unlocked. Remove
the battery housing by unscrewing the two fi xing screws. Carefully remove the fi lter from the lower catches and slide out the upper
catches. Install a new fi lter in place of the old one. Screw on the battery housing by tightening it with the fi xing screws. Place the
new fi lter in place of the old one. Carefully slide the upper fi lter catches into the fi xings until it is possible to lock the lower fi lter
catches. Gently press the lower part of the fi lter until the catches snap into place. A correctly installed fi lter should not move. En-
sure that a charged battery is correctly 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 generated 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
