SECTION 5 − MAINTENANCE
Cleaning
The helmet requires little maintenance. However, for best performance we rec-
ommend cleaning after use. Using a soft cloth dampened with a mild soap and
water solution, wipe the cover lenses clean. Allow to air dry.
Occasionally, the filter lens and sensors should be cleaned by gently wiping with
a soft, dry cloth. (Never use solvents or abrasive cleaning detergents. Do not
immerse the lens assembly in water).
SECTION 6 − TROUBLESHOOTING
Symptom Solution
Not ON – auto-lens will not
darken momentarily when
the Reset or On button is
pressed.
Check batteries and verify 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 has been dropped. Elite helmets only: verify left and right
battery trays are installed on the correct sides.
Not switching – auto-lens
stays light and will not
darken when welding.
Stop welding immediately: Press the Reset button if lens is Auto-
On type. If lens if Manual-On type, make sure the lens is turned
On. If power is on, review the sensitivity recommendations and
adjust sensitivity. Clean lens cover and sensors of any obstruc-
tions. 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 adjustments to
the control by turning it toward the “min” setting. In extreme light
conditions, it may be necessary to reduce the surrounding light
levels.
Sections of the auto-lens
are not going 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. 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. Increas-
ing Lens Delay 0.1 − 0.3 second may also reduce switching.
Inconsistent or lighter
auto-lens shading in the
dark-state, noticeable on
the outside edges and cor-
ners.
Referred to as an angle of view effect, auto-darkening lenses
have an optimum viewing angle. The optimum viewing angle is
perpendicular 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.
