Lincoln Electric IM10167 VIKING 3350 SERIES AUTO-DARKENING HELMETS - Manual (Page 8)

CARTRIDGE OPERATION/FEATURES
Variable Shade Control
The shade can be adjusted from shade 5 to 8 and 9 to 13 based upon welding
process or application (refer to shade selection chart on page 6). Shade is
adjusted by setting the shade range switch to the proper range, then use the
shade dual scale dial to set the desired shade. The shade range switch and dual
scale dial are located on the ADF cartridge as shown below.
Test Button
Press and hold test to preview shade selection before welding. When released
the viewing window will automatically return to the light state (3.5 Shade).
Sensitivity Knob
Adjust the light sensitivity by turning the SENSITIVITY knob to the left or right as
shown in the figure below. Turning the knob to the left increases sensitivity
which makes the ADF cartridge more sensitive to light. When 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 by turning the
knob to the right to reduce the sensitivity. Grind mode can be selected by rotating
the sensitivity knob all the way to the right until an audible click is heard.
Grind mode is intended for grinding only not for welding.
Delay Time Knob
This control is designed to protect the
welder's eyes from the strong residual
rays after welding. Changing the
DELAY knob will vary the dark to light
time between 0.1 second (S) to 1.0
second (L). The L setting is recom-
mended for high amperage applica-
tions where the weld puddle is still
very bright after the welding 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 bottom
corner 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.
