SAFETY WARNINGS – READ BEFORE USING
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.
FUMES 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 produce 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.

for additional safety information.

HELMET INFORMATION
This Auto-Darkening Welding Helmet will automatically change from a light
state (shade 3) to a dark state (Shade 7-13) when arc welding starts.
The filter automatically returns to a light state when the arc stops.
Shade control adjustments can be made while welding.
Match 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,
vibration 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
saturated.
This Auto-Darkening Welding Helmet is designed for use with GMAW, GTAW,
MMAW 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 two 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
immediately.
• Use only replacement parts specified in this manual.
• Do not use the helmet without inside and outside cover lenses properly
installed.

OPERATING INSTRUCTIONS
HEAD SIZE ADJUSTMENT: HEADGEAR TIGHTNESS is adjusted by
turning the Ratchet Knob left or right for the desired head size. This knob is
located at the back of the helmet. HEADGEAR CROWN ADJUSTMENT is
made by adjusting for comfort and snapping the pins into the holes to lock se-
curely in place.
TILT: Tilt adjustment is located on the right side of helmet. Loosen the right
headgear tension knob and push the top end of the adjustment lever outward
until the lever’s Stop Tab clears the notches. Then rotate the lever forward or
back to the desired tilt position. The Stop will automatically engage again
when released locking the helmet into position.
FORE / AFT ADJUSTMENT: Adjusts the distance between the user’s face
and the lens. To adjust, loosen the outside tension knobs and slide forward or
back to the desired position and retighten. NOTE: Make sure both sides are
equally positioned for proper operation.

CARTRIDGE OPERATION/FEATURES
Variable Shade Control
The shade can be adjusted from shade 7 to 13 based upon welding process or ap-
plication (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 figure below. Generally, turning the knob all the way to the right, or the high-
est setting, is selected for normal use. When the helmet is used in the presence of
excess ambient light or with another welding machine close by, improved helmet per-
formance 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
.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.

ALWAYS TEST TO BE SURE THE ADF CARTRIDGE IS CHARGED BE-
FORE WELDING. The TEST button is for the user to verify the ADF cartridge
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. When the shade control is set to
GRIND, the green light on the TEST button will flash green every 3 seconds.
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 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.

HELMET CARE AND MAINTENANCE
Replacing Front Cover Lens: Replace the front cover lens if it is damaged
– cracked, soiled or pitted. Place your finger or thumb into recess (C) at the
bottom edge of the cover lens and flex the lens upwards until it releases from
the edges marked A and B. (Refer to figure 1). Use only the replacement
front cover lenses specified in this manual.
Replace the Inside Cover Lens: if it is damaged (cracked, soiled or pitted).
Place your fingernail in recess above cartridge view window and flex lens
upwards until it releases from edges of cartridge view window.
Change the Shade Cartridge (See figure 2)
Fitting New Cartridge: Take the new shade cartridge and pass the
potentiometer cable under the wire loop before placing the cartridge into its
retaining frame inside the helmet. Hinge down the wire loop and ensure the
front edge of the loop (D) is properly retained under the retaining lugs (E) as
shown in (figure 3).
Position the shade potentiometer to the inside of the helmet with the shaft
protruding through the hole. Secure potentiometer to shell. On the outside of
the helmet, push the shade control knob onto the shaft.
Installing an Aftermarket Magnifying Lens: Unclip the wire loop (D) from
retaining lugs (E) and move hinge up. Place magnifing lens over ADF viewing
area and retain with wire loop.
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.

TROUBLE SHOOTING GUIDE
Test your shade cartridge prior to welding by directing the front of the
cartridge toward a bright source of light, then using your fingers rapidly cover
and uncover the sensors. The cartridge should darken momentarily as the
sensor is exposed. A torch striker can also be used.
