delay time for moving from dark to light shade, after interrupting the arc, according to the luminosity of the piece, only for model TW700S). Before using,
carry out a test with an arc strike.
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).
• 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 (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 glass (do not pour the product directly onto the filter).
