Remedy
Check batteries and verify they are 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. Verify left
and right battery trays are installed on the correct
sides.
Stop welding or cutting immediately: Make sure
the lens is turned On.
If power is On, check the mode settings. Also review
sensitivity recommendations and adjust sensitivity
if possible.
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 Sensitivity setting. In extreme light
conditions, it may be necessary to reduce the
surrounding light levels.
If the lens remains dark, press the On-Off button
to return lens to the clear state.
Trouble
Sections of the auto-lens are not going
dark, distinct lines separate the light
and dark areas.
Switching or Flickering – the auto-lens
darkens then lightens while the welding
or cutting arc is present.
Inconsistent or lighter auto-lens shading
in the dark-state, noticeable on the
outside edges and corners.
Remedy
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
0.1 − 0.3 second 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 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.
