Troubleshooting
Trouble
Auto lens does not turn
on when Mode Control
button is pressed.
Auto lens not switching;
lens stays light and
does not darken when
welding.
Auto lens not Switching;
lens stays dark after the
weld arc is extin-
guished, or the lens
stays dark when no arc
is present.
Sections of the auto-
lens are not going dark;
distinct lines separate
the light and dark areas.
Auto lens switching or
flickering; lens darkens
then lightens while the
welding arc is present.
Inconsistent or lighter
auto-lens shading in the
dark-state, noticeable
on the outside edges
and corners.

Remedy
Check battery and verify it is in good condition and installed
properly.
Check battery surfaces and contacts, and clean if necessary.
Check battery for proper contact and gently adjust contact points if
necessary. This is particularly important if the helmet has been
dropped.
Stop welding or cutting immediately.
If power is On, review the sensitivity recommendations and adjust
sensitivity.
Clean lens cover and sensors of any obstructions. Make sure the
sensors are facing the arc; angles of 45° or more may not allow the
arc light to reach the sensors.
Reduce the sensitivity setting by using the Sensitivity – button. In ex-
treme light conditions, it may be necessary to reduce the surround-
ing light levels.
Stop welding or cutting immediately: The auto-lens may be cracked
which can be caused by the impact of dropping the helmet.
Weld spatter on the auto lens may also cause cracking. (The lens
may need to be replaced; most cracked lenses are not covered by
warranty).
Review the sensitivity setting recommendations and increase the
sensitivity if possible. Be sure the arc sensors are not being blocked
from direct access to the arc light.
Check the lens cover for dirt and spatter that may be blocking the
arc sensors. Increasing Lens Delay may also reduce switching.
Referred to as an angle of view effect, auto-darkening lenses have
an optimum viewing angle. The optimum viewing angle is perpendic-
ular or 90° to the surface of the auto-lens. When that angle of view
varies in the dark-state, welders may notice slightly lighter areas at
the outside edges and the corners of the lens. This is normal and
does not represent any health or safety hazard. This effect may also
be more noticeable in applications where magnifying lenses are
used.
