luminous gradation of filter protection.
Adjust the "Sensitivity", in the models where planned, based on the luminous intensity of
the welding arc.
Adjust the "delay-time, in the models where planned, to set the delay time for passage from
the dark state to light state, after interrupting the arc and based on piece luminosity.
Before starting to weld, check the darkening of the ADF with the "TEST" button (if present)
or with a bright light source. If the ADF didn't switch to the dark mode, don't start welding.
After use and however before repositioning it after work, the helmet must be checked to
ensure it is intact and to eliminate any molten metal drops on the visual filter, which could
reduce performance of the filter.
The helmet must always be repositioned in such a manner to avoid its permanent
dimensional deformation or breaking the protective visual filter.
7. MAINTENANCE AND CLEANING
• Replace the transparent internal/external protection plates of the filter in the event of
breakage, scratches, nicks and deformations. Cheap guards compromise good vision of
what you are doing, dangerously lowering the level of protection of the helmet.
• Regularly clean the surface of the filter and the protection plates with a soft cloth with
non-aggressive cleaning solutions, for example window cleaning formulas (do not pour
the product directly on the filter).
• Clean and disinfect the helmet only with water and soap or solvent-free products. Use
of chemical products causes aesthetic defacing even up to a complete reduction in the
intactness of the helmet.
• Good general care of the helmet allows to reduce its obsolescence to the minimum, both
from the point of view of use and that of components on the helmet.
• Regularly clean the surface of the filter with a soft cloth with non-aggressive cleaning
solutions, for example window cleaning formulas (do not pour the product directly on the
filter).
8. TROUBLESHOOTING
During helmet operation, common problems may arise, listed here with the relevant
solutions:
• Poor visibility.
Possible solution:
- The external guard and/or the internal guard of the filter and/or the filter are dirty or
damaged (clean the dirty components and replace damaged ones).
- The surrounding ambient does not have sufficient light (provide more light to the
surrounding ambient).
ATTENTION!
If the aforementioned malfunctions cannot be resolved, immediately
suspend use of the helmet and contact your nearest distributor.
