Lincoln Electric VIKING 3350 Series Operator's Manual page 8

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.
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
recommended for high amperage
applications 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.
