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 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.
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 9-13) 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, 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 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 imme-
diately.
• 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: Headband tightness is adjusted by pushing in the
ratchet knob and turning to adjust to desired comfort level. This knob is
located at the back of the helmet. HEAD GEAR CROWN ADJUSTMENT is
made by adjusting crown strap for vertical placement on the head and snap-
ping the pin into the hole to lock securely in place.
Tilt: Tilt is adjusted on the left side of the helmet. TILT is adjusted by loos-
ening outside tension knob and releasing the adjustment lever from its cur-
rent location and moving it to another location. Retighten the outside tension
knob when finished.

CARTRIDGE OPERATION/FEATURES
Variable Shade Control
The shade can be adjusted from shade 9 to 13 based upon welding process or
application (refer to Shade selection chart on page 6). The variable shade control
knob is mounted to shell for external adjustment.
Sensitivity Control
You can adjust the light sensor by selecting the HIGH or LOW position of the
sensitivity switch as shown in figure below. Generally, the HIGH setting is select-
ed for normal use. Where the helmet is used in the presence of excess ambient
light or with another welding machine close by, the LOW setting may be selected
for better performance.
Delay Time Control
This control is designed to protect the welder’s eyes from the strong residual rays
after welding. You can delay the time of change to light state from the darkened
state with setting delay control switch on FAST or SLOW. The SLOW 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.
Solar Power
This helmet is powered by solar energy. As such, there is no battery that requires
replacement.

ALWAYS TEST TO BE SURE THE ADF CARTRIDGE IS CHARGED
BEFORE WELDING. The helmet can be placed in sunlight to charge. Do not
store the helmet in a dark cabinet or other storage area for long periods.
While welding, the arc also charges the ADF cartridge.

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

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.
Data from ANSI Z49.1-2005
If your helmet does not include any one of the shades referenced above, it is
recommended you use the next darker shade.

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 poten-
tiometer cable under the wire loop before placing the cartridge into its retain-
ing 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.
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 car-
tridge 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.
