HELMET INFORMATION
This Auto-Darkening Welding Helmet will automatically change from a light
state (shade 3.5) to a dark state (Shade 5-13) when arc welding starts.
The filter automatically returns to a light state when the arc stops.
atch your welding application to the shade indicated on the shade chart.
(See Page 6)
• Operating temperature: 14°F ~ 131°F (-10°C ~ 55°C).
• Do not use or open the auto-darkening filter if damaged by shock, vibra-
tion or pressure.
• Keep the sensors and solar cell clean. Clean the filter cartridge using a
soapy water solution and soft cloth which should be damp but not saturat-
ed.
This Auto-Darkening Welding Helmet is designed for use with G AW, GTAW,
AW welding, or Plasma Arc and air carbon arc cutting.
The cartridge provides protection from harmful UV and IR radiation, in both
dark and light states.
The cartridge contains four sensors to detect the light from the welding arc,
resulting in the lens darkening to a selected welding shade.
• Do not use solvents or abrasive cleaning detergent.
• If cover lens is spattered or covered with dirt, it should be replaced imme-
diately.
• Use only replacement parts specified in this manual.
• Do not use the helmet without inside and outside cover lenses properly
installed.

SAFETY WARNINGS – READ BEFORE SING
ARC Rays can injure eyes and burn skin
• Before welding, always inspect helmet and filter lens to be sure they are fitted
properly, in good condition and not damaged.
• Check to see that the clear lens is clean and securely attached to the helmet.
• Always wear safety glasses or goggles under the welding helmet and protective
clothing to protect your skin from radiation, burns and spatter.
• Ensure that optical radiation from other welder’s arcs in the immediate area
does not enter in from behind the helmet and auto-darkening filter.
Note: Auto-darkening filters in Lincoln helmets are designed to protect the user against harmful
ultra-violet and infrared rays both in the dark and light states. No matter what shade the filter is
set to, the UV/IR protection is always present.
F MES AND GASES can be dangerous to your health.
• Keep your head out of fumes.
• Use enough ventilation or exhaust at the arc or both to keep fumes and gases
from your breathing zone and general area.
• When welding with electrodes which require special ventilation such as
stainless or hard facing (see instructions on container or MSDS) or on
lead or cadmium plated steel and other metals or coatings which pro-
duce highly toxic fumes, keep exposure as low as possible and within
applicable OSHA PEL and ACGIH TLV limits using local exhaust or
mechanical ventilation. In confined spaces or in some circumstances,
outdoors, a respirator may be required. Additional precautions are also
required when welding on galvanized steel.

CARTRIDGE OPERATION/FEAT RES
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 left 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 Time
knob will vary the dark to light time between
0.1 second (S) to 1.0 second (L). The Lset-
ting 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 two
replaceable batteries and solar power. The
batteries are located at the bottom of the
ADF cartridge. Replace batteries when
LOW BATTERY light is lit. See the specifi-
cation chart on page 3 for type of batteries required.

(1) As arule 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.
