EASTWOOD WELDING HELMETS are specifically designed to provide maximum eye and face
protection from harmful UV and IR radiation emitted when welding, in a lightweight, comfortable
housing. The Large Viewing area provides additional visibility for added safety and convenience.
Auto-Darkening powered by solar cells and Lithium #CR2450 batteries provide long, reliable life.
Meets ANSI Z-87.1 safety standards.
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION used with the safety alert symbol, indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE is used to address practices not related to personal injury.

ELECTRIC SHOCK CAN CAUSE
INJURY OR DEATH!
• Improper use of an electric welder and associated equipment can cause
electric shock, injury and death! Read all precautions described in the
specific Welder Manual to reduce the possibility of electric shock.
• The electrode and work (or ground) circuits are electrically “hot” when the
welder is on. Do not allow these “hot” parts or associated equipment to
come in contact with your bare skin or wet clothing.
• Separate yourself from the welding circuit by using insulating mats, protec-
tive clothing, leather welding gloves and insulated footwear to avoid being
part of the welding circuit.
• Be sure that the work piece is properly supported and grounded prior to
beginning an electric welding operation.
• If other persons or pets are in the area of welding, use welding screens
to protect bystanders from sparks and harmful arc rays.
EYE INJURY HAZARD!
• If other persons or pets are in the area of welding, use welding screens to
protect bystanders from sparks and harmful arc rays.
• Inadequate levels of arc ray shading can cause permanent eye injury. This
helmet is capable of protection up to shade level 13 only. If your particular
welding process emits arc radiation that requires a shade level higher than
13, DO NOT use this helmet and seek alternate protection.
• Eastwood welding helmets are designed to protect the user’s eyes and face
from harmful radiation, sparks and spatter under normal welding conditions.
They are not intended to offer protection against impact hazards, explosions
or corrosive liquids.
• Wear ANSI approved impact safety goggles under welding helmet.
• Always test Auto-Darkening feature before each use by quickly subjecting
the face of the Welding Helmet to sunlight or other bright light source. If the
Auto-Darkening feature fails to function, permanent eye damage can occur
from exposure to welding flash and radiation, DO NOT USE
• The operating temperature range of the Auto-Darkening feature is 23°F
to 130°F (-5°C to 55°C). The response time may be affected beyond the
described temperatures causing an unsafe condition. DO NOT USE beyond
recommended operating temperature range.
• DO NOT USE this helmet for oxy-acetylene welding or cutting processes,
laser welding or low amperage (less than 10 amps) TIG welding.

OPERATION
• Remove the protective film from the inside
and outside surfaces of the lens.
• With normal (non-welding), ambient light,
your view through the lens will have a
slight tint. When exposed to bright light or
the flash of the welding arc, the lens will
quickly darken your view.
The Sensitivity, Delay and Shade controls and
switches are located at the upper panel of the
viewing area inside of the Welding Helmet and
are adjustable as follows: (FIG 1).
SENSITIVITY
Sensitivity controls the Auto-darkening response
when exposed to smaller arcs such as low-
amperage TIG welding and conditions like welding outside in bright sunlight.
To Adjust Sensitivity: Turn dial Clockwise to increase sensitivity for low amperage welding.
Turn Counter-Clockwise when welding in sunlight or bright ambient light.
This helmet also has a “GRIND” setting which turns off the Auto-Shade feature and keeps the viewer
on base transparency to allow use of the Helmet for grinding and other non-welding uses.
To Set Sensitivity Control to “Grind”: Rotate the Sensitivity Control Knob past the detent fully to the
“GRIND” position which will lock the viewer on full transparency.

To avoid serious and permanent eye damage, NEVER attempt to weld with the
Sensitivity Control set to “GRIND”.
DELAY
Delay controls the time interval for the Auto-darkening to return to normal view once arc is stopped.
To Adjust Delay: Turn dial Clockwise to increase delay time for helmet to return to normal view after
arc is stopped. Turn Counter-Clockwise to minimize the time for the helmet to return to normal view.
EYE INJURY HAZARD!
• Inadequate levels of arc ray shading can cause permanent eye injury. This
helmet is capable of protection up to shade level 13 only. If your particular
welding process emits arc radiation at levels higher than 13, DO NOT use this
helmet and seek alternate protection.
• Do not use this helmet for oxy-acetylene welding or cutting processes, laser
welding or low amperage (less than 10 amps) TIG welding.

SHADE
Shade is used to control the level of darkness as Auto-darkening is automatically activated when
an arc is present.
The Shade Control Knob is designed to function in 2 separate ranges; one for shade levels 5 through 9
and one for shade levels 9 through 13. Shade 5 is lightest while shade 13 is darkest. Move the Shade
Range Switch to the left for levels 5-9; to the right for levels 9-13.
To Adjust Shade:
Consult the SHADE GUIDE TABLE (FIG 2) to verify that this helmet provides adequate protection for
your preferred welding process before using.
If unsure of shade level required, use the following procedure to find the correct shade level:
• Set the Range Switch to the 9-13 position, set Knob to 13 and try viewing with an expected
arc, then continue to decrease the setting while striking an arc until it is visible with Auto-
Darkening. This is the correct setting.

ADJUST FIT OF HELMET:
Headband – Push Knob in and Turn Clockwise to decrease size (tighten) or rotate Counter-Clockwise
to increase size (loosen).
Width/Height – Push in rectangular latch on the two overhead bands, slide bands in to shorten band
or pull out to lengthen bands. Snap button into the nearest available rectangular holes.
Flip-up Retention – This will allow the helmet to stay in the “flipped-up” position. Tighten or loosen
knobs on either side of the helmet to increase or decrease friction.
MAINTENANCE
• The Red LED “Low-Bat” Lamp is located on the upper, inner panel above the viewing area to
the right of the Control Knobs (FIG 1). If it is illuminated, the batteries may require a charge by
exposing the face of the Welding Helmet to bright sunlight for several hours. If this fails to extin-
guish the light, the batteries will require replacement. If this becomes necessary, replace with
two 3V type CR2450 by following the “Replace Batteries” section below.
REPLACE BATTERIES:
- Note location on panel of view frame inside
of Helmet, press in and down on raised ribs
of Battery Covers to unlatch and remove Covers
(FIG 3).
- Remove Batteries.
- Replace Batteries with 3V type CR2450
with positive side facing upward.
- Replace Battery Covers and snap back into place.
• Clean outside and inside of lens with a soft cloth and
small amount of glass cleaner. NOTE: Do not use excessive glass cleaner or allow the lens
assembly to become wet or the sensitive electronics will be destroyed. Never use solvents.
• Clean headband with a cloth dampened with mild soap and water. Allow to dry thoroughly.
• Check lens assembly for damage before each use. If cracked or broken, DO NOT USE.
REPLACE OUTER SHIELD:
- Insert tip of the forefinger into the semi-circular
recess at the bottom of the viewing area, pry the
Lens up while curling it outward in the center,
then out and away from Helmet (FIG 4).
- Reverse to install by squeezing sides to curl
the center outward then insert edges into
channels around frame of opening (FIG 4).
