3-7. Power Modes
The auto-darkening lens has three
power modes: sleep (off), standby, and
on. The lens goes to sleep automatical-
ly when ambient light is low (less than
3 lux). The lens consumes less than 1
microamp of battery power when in the
sleep mode.
When ambient light exceeds10 lux, the
lens automatically changes to the
standby mode and is ready for welding.
The lens relies on the solar cell for pow-
er when in standby mode.
When welding begins, the lens auto-
matically turns on (darkens). In most
cases, the solar cell provides enough
power to operate the lens during weld-
ing. However, the lens may use both
solar and battery power when shade
control is at a high setting.
The lens returns to standby mode im-
mediately after welding stops, and then
enters sleep mode if ambient lighting is
low (less than 3 lux).
