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 welderʼs arcs in the immediate area
does not enter in from behind the helmet and auto-darkening filter.

Auto-darkening filters in Lincoln helmets are designed to protect the user against harmful

Note:

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 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.

Match your welding application to the shade indicated on the shade chart.
(See Page 8)

• 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. This helmet also
has cutting and grinding modes.

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.

• Do not use helmet if lens does not function as described.

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” but-

ton 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 (See Fig-8,

-9, Items A and B). 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. (See Fig-8,-9,
Items C and D).

Grind Mode − 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
applications 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.
