injury.
• Insert two CR2032-type batteries into the filter before using the mask (FIG. B).
• Replace the two CR2032-type batteries if the LED does not light up after pressing the "BATT" key.
PRECAUTIONS
For your protection and to ensure that your self-darkening welding filter is properly working, carefully read these instructions
and consult with a qualified instructor or supervisor prior to operation.
• These welding filters are suitable for use with virtually all welding processes except for Oxy-Acetylene welding, plasma
welding, laser welding.
• Standard polycarbonate clear protective plate must be installed on both the inside and outside surfaces of the filters.
• Failure to use protective plates may constitute a safety hazard or result in irreparable damage to the filter.

MAINTENANCE

• Frequently check the helmet components and replace any worn or damaged parts.
• Replace the external/internal transparent filter protection if it is broken, scored, scratched and out of shape. Damaged
protections impair the vision of the user, which lowers helmet protection to a dangerous level.
• Regularly clean the filter surface with a soft cloth and a non-aggressive cleaning solution, for example one for cleaning
glass (do not pour the product directly onto the filter).
• Get into the habit of making sure that the solar cells and the sensors have not darkened or are not covered in dirt. If they
have or if they are, clean them with a soft paper tissue, if necessary slightly dampened with a preparation for cleaning
glass (do not pour the product directly onto the filter).
INSTRUCTIONS FOR USE
The helmet must always and only be used to protect the face and eyes during welding. It was designed to guarantee
maximum protection during welding, to be easy to assemble, comfortable to wear and of top quality when used.
The helmet and consequently the filter glass viewing area, must be kept as close as possible to the eyes during welding, in
order to protect them from the electric arc and possible drops of molten metal.
After using the helmet and before putting it away after working, it must be checked to verify integrity and to eliminate any
drops of molten metal that may be present on the viewing filter, which can reduce its visual performance.
The helmet must be placed in a way that does not allow its dimensions to deform permanently, or the viewing filter to break.
Before starting to weld make sure that the filter and the internal and external transparent protections are correctly positioned.
Where possible, adjust the "shade" according to the current and the welding process. Table 1 gives the recommended
"shade" numbers for using an electric arc welding machine to carry out common jobs and the different welding current
intensity levels. Where possible, adjust "Sensitivity" according to the light intensity of the welding arc (where possible, adjust
"delay-time" to set the delay time for moving from dark to light shade, after interrupting the arc, according to the luminosity
of the piece). Before using, carry out a test with an arc strike.
When in the "GRIND" mode, the mask can be used for grinding process.

TROUBLESHOOTING

Some common problems listed below, together with their possible solutions, can arise when using the helmet:
• The filter does not darken or is unstable when switching from light to dark and viceversa.
Possible solution.
- The external transparent protection of the filter is dirty or damaged (change the external transparent protection).
- The sensors are dirty (clean the sensor surface).
- The level of the welding current level is too low (increase sensitivity).
- The batteries are not in good condition or not properly inserted (replace the batteries or remove them and re-insert
them properly).
- Battery terminals and the contact surfaces of the filter are dirty or oxidized (clean both).
- The DIN adjustment knob of the filter is in the "GRIND" position (rotate the knob).
• Slow switching.
The operating temperature is too low (do not use at temperatures of below -5°C (+23°F).
• Poor visibility.
- The external or/and internal protection of the filter is/are dirty or damaged (clean the dirty components and replace the
damaged ones).
- Not enough light in the surrounding area.
- The scale number is not set correctly (where possible, select the correct number).
ATTENTION!
If the described malfunctions cannot be solved, stop using the helmet immediately and contact the nearest
distributor.

CLEANING AND DISINFECTING

• Only use soap and water or products that do not contain solvents to clean and disinfect the helmet. Using chemical
solvents ruins the aesthetics of the helmet and can dramatically reduce its integrity.
• Taking good general care of the helmet reduces its obsolescence to a minimum, both from a use and a helmet component
point of view.
• Regularly clean the filter surface with a soft cloth and a non-aggressive cleaning solution, for example one for cleaning
glass (do not pour the product directly onto the filter).
• Get into the habit of making sure that the solar cells and the sensors have not darkened or are not covered in dirt. If they
have or if they are, clean them with a soft paper tissue, if necessary slightly dampened with a preparation for cleaning
