3 / AUTO-DARKENING FILTER/LENS (ADF) CONTROLS & FEATURES
Note: ADF = Auto-Darkening Filter/Lens
a. POWER SUPPLY
Promax 180, 200: Solar powered with internal re-chargeable, non-replaceable
battery Promax 350, 500: 1 replaceable battery, plus solar-assistance via a solar panel
on the front of the ADF which absorbs energy from the welding arc. The solar panel
supports the battery to extend battery life whilst the helmet is activated, however it
will not power the helmet alone. The batteries are not re-chargeable - if the batteries
are discharged, they must be replaced with new batteries.
b. ON / OFF
(Excludes Promax 180)
When the switch is in the ‘WELD’ position, the ADF is ready to weld at any time.
IMPORTANT: For maximum battery life, switch the ADF to ‘GRIND’ position when
the helmet is not in use. This will turn it off & prevent any nearby light sources from
activating the ADF and discharging power.
To conserve power, the ADF will automatically switch to ‘sleep mode’ if it does not
detect an arc for a period of 10 minutes, and will automatically switch on as soon as
an arc is detected. [Promax 350 & 500 only].
