Section 9 - Troubleshooting
TROUBLE REMEDY
Auto lens not on – Auto-lens will
not darken momentarily when
exposed to welding arc.
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.
Auto-lens not switching –
Auto-lens stays light and will not
darken when welding or cutting.
Stop welding immediately.
Make sure the lens is in the Weld On mode. When in
the Weld On mode the lens will darken for welding
applications. Do not weld in the Grind On mode; the
lens will not darken.
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
obstructions. Make sure the sensors are facing the
arc; angles of 45 or more may not allow the arc light
to reach the sensors.
Auto-lens not switching –Auto-lens
stays dark after the weld arc is ex-
tinguished, 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. Increasing 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 corners.
Referred to as an angle of view effect, auto-darkening
lenses have an optimum viewing angle. The optimum
viewing angle is perpendicular or 90 degrees 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.
