batteries to function properly.
Replacement of the batteries: The batteries are located in the welding helmet shell. Remove the fi lter as described in the next
section of this manual, then remove the battery compartments and replace both batteries (III). Two CR 2032 type batteries are
required to power the fi lter. Pay attention to the correct polarity when installing the batteries. Always replace batteries in pairs.
Replacing the protective glass panels
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 (IV) 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 (V). 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 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 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 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
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
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 conjunc-
tion 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
storage, do not exceed the temperature range of -20
handbags, etc.) Protect against mechanical damage. Transport in the supplied unit packaging in carton boxes using closed transport.
Declaration of Conformity: Available at toya24.pl in the product data sheet.
