Lincoln Electric IM10165 VIKING 1840 SERIES AUTO-DARKENING HELMETS - Manual (Page 8)

CARTRIDGE OPERATION/FEATURES
Variable Shade Control
The shade can be adjusted from shade 9 to 13 based upon welding process or
application (refer to Shade selection chart on page 6). The variable shade control
knob is mounted on the exterior of the helmet shell. Grind mode can be selected
by rotating the shade control knob counterclockwise till an audible click is heard.
Grind mode is intended for grinding only not for welding.
Sensitivity Knob
You can adjust the light sensor by turning the Sensitivity knob to the left or right as shown in the figure
below. Turning the knob to the right increases sensitivity which makes the ADF cartridge more sensi-
tive to light. When the helmet is used in the presence of excess ambient light or with another welding
machine close by, improved helmet performance can be obtained with a lower setting turning the knob
to the left to reduce the sensitivity.
Delay Time Knob
This control is designed to protect the welder’s eyes from the strong residual rays after welding.
Changing the Delay Time knob will vary dark to light time between 0.1 second (minimum) to 1.0 sec-
ond (maximum). Turning the Delay Time knob to the right is maximum (1.0 second). This setting is
recommended for high amperage applications where the weld puddle is still very bright after the weld-
ing arc has ceased and for situations where the filter may be temporarily blocked from seeing the
welding arc.
Power
This ADF cartridge is powered by a replaceable battery and solar power. The battery is located at the
top of the ADF cartridge. Replace battery when LOW BATTERY light is lit. See the specification chart
on page 3 for type of battery required.

HELMET CARE AND MAINTENANCE
Cleaning: Clean helmet by wiping with a soft cloth. Clean cartridge surfaces
regularly. Do not use strong cleaning solutions. Clean sensors and solar cells
with soapy water solution and a clean cloth and wipe dry with a lint-free cloth.
Do NOT submerge shade cartridge in water or other solution.
Storage: Store in a clean, dry location.
SHADE GUIDE SETTINGS
If your helmet does not include any one of the shades referenced above, it is
recommended you use the next darker shade.

(1)
As a rule of thumb, start with a shade that is too dark, then go to a lighter shade which gives sufficient view of the weld zone without going
below the minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow light, it is desirable to use a filter lens that absorbs
the yellow or sodium line the visible light of the (spectrum) operation
(2) These values apply where the actual arc is clearly seen. Experience has shown that lighter filters may be used when the arc is hidden by the
workpiece.
