Additional Instructions
• Be sure that the helmet is used in the correct condition and according to the
safety requirements.
• There is a liquid crystal-valve in the filter, although it has inner and outer protection
covers, it is important to avoid heavy knocks to the helmet.
• The outer protective shell of the helmet should be periodically inspected and cleaned. In
the case of a break, crack, pitting or other damage, the helmet shell must be replaced.
• To operate more efficiently and safely, please select the correct dark shade number.
• The arc light must be visible completely by all arc sensors. If not, the ADF may struggle to
detect an arc and may not activate the selected shade.
• Please use the automatic filter at a temperature between -10°C-65°C (14°F-149°F).
• Do not disassemble the filter. If any problems arise, please contact your local UNIMIG
service department.
