SAFE Y WARNINGS – READ BEFORE USING
ARC Rays can injure eyes and urn skin
• Before welding, always inspect helmet and filter lens to
e 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, urns and spatter.
• Ensure that optical radiation from other welder’s arcs in the immediate
area does not enter in from ehind 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 oth 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 e dangerous
to your health.
• Keep your head out of fumes.
• Use enough ventilation or exhaust at the arc or oth to
keep fumes and gases from your reathing 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 possi le and within
applica le OSHA PEL and ACGIH TLV limits using local exhaust or
mechanical ventilation. In confined spaces or in some circumstances,
outdoors, a respirator may e required. Additional precautions are also
required when welding on galvanized steel.

WARNING
Refer to http://www.lincolnelectric.com/safety
for additional safety information.

ALWAYS ES O BE SURE HE ADF CAR RIDGE IS CHARGED
BEFORE WELDING. The ES 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.
SHADE GUIDE SE INGS
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.

HELME INFORMA ION
This auto darkening welding helmet with integrated clear face shield is an all-
in-one solution for welding, cutting and grinding. It is designed to provide
protection from harmful UV and IR radiation from welding/cutting process
with the lens flip down, and help protect against flying particles from grinding
with the lens flip up. This Helmet can be used for G AW, GTAW, AW
welding, or Plasma Arc and air carbon arc cutting.
This Auto-Darkening Welding Helmet will change from a light state (shade 4)
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.
• The lens must flip down before welding.
• Do not use the auto-darkening filter if damaged by shock, vibration or
pressure.
• Do not use the helmet without inside and outside cover lenses properly
installed.
• If cover lens is spattered or covered with dirt, it should be replaced
immediately.
• Do not use helmet if lens does not function as described.
The cartridge contains four sensors to detect the light from the welding arc,
resulting in the lens darkening to a selected welding shade. 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.
• Do not use solvents or abrasive cleaning detergent.
• Use only replacement parts specified in this manual.

Headgear Adjustment
FIGURE 1
HEAD SIZE ADJUSTMENT: HEADGEAR TIGHTNESS is adjusted by
pushing in the Ratchet Knob and turning to adjust 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
inward 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, press the button down and slide forward or back to
desired position, and then released the button. NOTE: ake sure both sides
are equally positioned for proper operation.

ON/MODE Button
•ON-OFF (Lens will automatically darken when arc is present)
The Shade Cartridge will automatically turn on, the digital display control
will activate and helmet will be ready for use. It is recommended that the
user review helmet settings prior to use. The welding helmet will
automatically turn off after half hour of no use.
•MODE CONTROL
Short press of the
ON/ ODE button
to select the mode
appropriate for the
work activity:
Weld Mode − used for most welding applications. Push "FUNC" button
to adjust shade number, sensitivity, and delay settings before welding. In
this mode, the lens turns to dark immediately when you start welding.
Cutting Mode − used for cutting applications. Push "FUNC" button to
adjust shade number, sensitivity, and delay settings before cutting. In
this mode the lens turns to dark immediately when you start cutting.
Grind Mode − used for grinding applications. In this mode the lens
shade is fixed shade No. 4. Shade number, sensitivity, and delay
settings cannot be adjusted when in grind mode.
Battery Indicator
The symbol " "
shows the current state
of the battery. The
volume of batteries has
four level symbols (See
Figure 3). The symbol
" " appears on the
display screen before 1 to 2 days of battery life remains, CR2450 lithium
batteries should be replaced at this time. The symbol of the Battery Indicator
is not real-time and is updated shortly after pushing the ON/ ODE button.

Variable S ade Control
After turning on the lens,
press the "FUNC" button
to choose “SHADE”,
adjust lens shade
number. Use the shade
control UP and DOWN
buttons to select the lens darkened state.
The shade range for each mode is as follows:
• Weld ode − No. 9 ~ No. 13
• Cutting ode − No. 5 ~ No. 8
• Grind ode - No. 4
Sensitivity Control
Press "FUNC" button to
choose "SENSITIVITY".
Use Sensitivity Control
"UP" and "DOWN"
buttons to make the lens
more or less sensitive to
arc light for different welding processes. Sensitivity settings 5 through 9 are
the normal settings for everyday use. The sensitivity ranges for each mode
are as follows:
• Weld ode / Cutting ode − No.0 ~ No. 10
• Grind ode − No sensitivity adjustment
It may be necessary to adjust helmet sensitivity to accommodate different
lighting conditions or if lens is flashing On and Off. Adjust helmet sensitivity
in lighting conditions helmet will be used in. Adjust helmet sensitivity as
follows:
• Press the “DOWN” button to lower setting to 0.
• Face the helmet in the direction of use, exposing it to the surrounding
light conditions.
• Press the “UP” button repeatedly until the lens darkens, then press the
“DOWN” button until lens clears. Helmet is ready for use. Slight
readjustment may be necessary for certain applications or if lens is
flashing on and off.

Delay Control
Press "FUNC" button
to choose "DELAY",
begin lens delay
adjustments. Use the
Lens Delay Control
"UP" and "DOWN"
buttons to adjust the time for the lens to switch to the clear state after welding
or cutting.
• Weld ode / Cutting ode − No.0 ~ No. 10
• Grind ode − No delay adjustment
The delay is particularly useful in eliminating bright after-rays present in higher
amperage applications where the molten puddle remains bright momentarily
after welding. Use the Lens Delay Control buttons to adjust delay from 0 to 10
(0.1 to 1.0 second). When welding ceases, the viewing window automatically
changes from the darkened state back to light state but with a pre-set delay to
compensate for any bright afterglow on the work piece. The delay
time/response can be set from Level 0 to level 10. It is recommended to use a
shorter delay with spot welding applications and a longer delay with appli-
cations using higher currents. Longer delays can also be used for low current
TIG welding in order to avoid the filter opening when the light path to the
sensors is temporarily obstructed by a hand, torch, etc.
