10-7. Power Modes
The auto-darkening lens has
three power modes: sleep
(off), standby, and on. The
lens goes to sleep automati-
cally when ambient light is low
(less than 3 lux). The lens
consumes less than 1 micro-
amp of battery power when in
the sleep mode.
When ambient light exceeds
10 lux, the lens automatically
changes to the standby mode
and is ready for welding. The
lens relies on the solar cell for
power when in standby mode.
When welding begins, the
lens automatically turns on
(darkens). In most cases, the
solar cell provides enough
power to operate the lens dur-
ing welding. However, the lens
may use both solar and bat-
tery power when shade con-
trol is at a high setting.
The lens returns to standby
mode immediately after weld-
ing stops, and then enters
sleep mode if ambient lighting
is low (less than 3 lux).
