SECTION 6 − TROUBLESHOOTING
Symptom Solution
Not ON – auto-lens will not darken
momentarily when turned on.
Check batteries and make sure that they are in good
condition and installed properly. Also, 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 may have been dropped.
Not switching – auto-lens stays light
and will not darken when welding.
Stop welding immediately: Make sure the auto-lens
power is turned ON. 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.
Not Switching – auto-lens stays dark
after the weld arc is extinguished, or
the auto-lens stays dark when no arc
is present.
Fine-tune the sensitivity setting by making small adjust-
ments to the control by turning it toward the “Low” set-
ting. In extreme light conditions, it may be necessary to
reduce the surrounding light levels.
Sections of the auto-lens are not go-
ing dark, distinct lines separate the
light and dark areas.
Stop welding 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).
Switching or Flickering – the auto-
lens darkens then lightens while the
welding arc is present.
Review the sensitivity setting recommendations and
increase the sensitivity if possible. Make sure that 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.
Inconsistent or lighter auto-lens
shading in the dark-state, noticeable
on the outside edges and corners.
Referred to as an angle of view effect, auto-darkening
lenses have an optimum viewing angle, perpendicular,
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 notice-
able in applications where magnifying lenses are used.
