Lincoln Electric IM10150 VIKING 1740 SERIES AUTO-DARKENING HELMETS - Manual (Page 7)

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 located on the ADF cartridge as shown below.
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 all the way to the right is the HIGH setting. 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 left to reduce the sensitivity.
Delay Time Knob
This control is designed to protect the welderʼs eyes from the strong residual rays after welding. Changing the
Delay Time knob will vary dark to light time between .1 second (minimum) to 1.0 second (maximum). Turning
the Delay Time knob to the left is maximum (1.0 second). This 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 replaceable batteries and solar power. Battery installation is required prior
to use. The batteries are located at the top of the ADF cartridge. Replace batteries when LOW BATTERY light
is lit. See the specification chart on page 3 for type of batteries required.
Weld/Grind switch
Switch to be set to WELD for welding operation. GRIND setting is intended for grinding only not for welding.

ALWAYS TEST TO BE SURE THE ADF CARTRIDGE IS CHARGED
BEFORE WELDING. The TEST button is for the user to verify the ADF car-
tridge is darkening properly. If cartridge is not darkening properly, replace
batteries with fresh batteries and test again before use. While welding, the
arc and solar cell will keep the ADF charged.
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.
