SECTION 8 − MAINTENANCE
NOTICE − Never use solvents or abrasive cleaning detergents.
NOTICE − Do not immerse the lens assembly in water.
The helmet requires little maintenance. However, for best performance clean
after each 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.
SECTION 9 − TROUBLESHOOTING
Trouble Remedy
Auto-lens not On; auto-
lens does not darken mo-
mentarily when arc is
struck 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.
Auto-lens not switching –
auto-lens stays light and
does not darken when
welding or cutting.
Stop welding immediately. Make sure the lens is on. 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.
Review sensitivity recommendations and adjust sensitivity if pos-
sible. Do not weld in the Grind On mode; the lens will not darken.
Auto-lens not switching –
auto-lens stays dark after
the 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 or cutting immediately.
The auto-lens may be cracked which can be caused by the im-
pact 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).
