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.

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.

OPERATING INSTRUCTIONS
Headgear Adjustment
HEAD SIZE ADJUSTMENT: HEADGEAR TIGHTNESS is adjusted by turning
the Ratchet Knob to the right or left to adjust for the desired head size.
This knob is located at the back of the helmet. HEADGEAR CROWN
ADJUSTMENT is made by adjusting the comfort then placing the strap under
the guide 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, slide and hold the spring loaded caps upward while mov-
ing the headgear into one of four slotted locations. Once the desired distance
has been achieved let go of the cap and it will return to its resting position
once the adapter is secured in one of the four slots. NOTE: Make sure both
sides are equally positioned for proper orientation.

GRIND BUTTON OPERATION
In order to switch the Auto Darkening Filter from a Cutting or Welding Shade
into Grind Mode first locate the silicone button on the left side of the helmet.
After the button has been located press and hold it for 3 seconds. A green
LED on the cartridge should blink every 3 seconds after the button is pressed
to indicate you are in Grind mode. To switch back to the previous Cutting or
Welding shade simply press and hold the button for 3 seconds. Grind mode
is intended for grinding only not for welding.

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.
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 Lsetting 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.

(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.
