SAFETY WARNINGS – READ BEFORE USING
WARNING
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.
Refer to http://www.lincolnelectric.com/safety
for additional safety information.

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.
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 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 immediately.
• Use only replacement parts specified in this manual.
• Do not use the helmet without inside and outside cover lenses properly installed.

Adjustment
HEAD SIZE ADJUSTMENT: HEADGEAR TIGHTNESS is adjusted by turning
the Ratchet Knob to the right or left 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 securely in place.
TILT: Tilt adjustment is located on the right side of the 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 lens. To adjust, loosen the outside tension knobs and slide forward or back
to 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 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.
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 specification chart
on page 3 for type of batteries required.

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 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.

(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

CARTRIDGE AND LENS REPLACEMENT
Replacing Front Clear Cover Lens: Replace the front cover lens if it is damaged.
Remove ADF holder assembly per Figure 1. Remove front cover lens from helmet
assembly. Carefully remove gasket from cover lens. Install new cover lens into
gasket and assemble to helmet shell. Make sure to assemble cover lens and gasket into helmet shell the same way as it was removed.
Replacing Inside Clear Lens: Replace the inside clear lens if it is damaged. Place
your fingernail in recess below cartridge view window and flex lens upwards until it
releases from edges of cartridge view window.
Change the Shade Cartridge: Remove ADF holder assembly from helmet shell.
See figure 1 for removal. Flex top end of the ADF holder to allow for ADF cartridge
to be removed from frame. Install new ADF cartridge into frame per figure 2 below.
Make sure that the ADF cartridge is inserted in ADF holder correctly as shown. Install ADF holder assembly into helmet shell.

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.
