SECTION 1 - SAFETY WARNINGS –READ BEFORE USING
ARC RAY FROM WELDING CAN BURN EYES AND SKIN. A damaged helmet or
auto-darkening filter (ADF) can reduce the protection against harmful rays (intense visible light,
ultraviolet and infrared) and result in serious injury.
•Before welding, always inspect the complete helmet and the filter to ensure that they are
not damaged. Also check and select the right shade and other filter settings.
•Check both the front and back cover lens to see whether they are clean, clear,
undamaged and securely attached to the helmet and cover the auto-darkening filter.
They are for the protection of the ADF. Never weld without the cover lenses on.
•Replace any worn or damaged parts immediately.
•Damages to ADF caused by abuse such as excessive temperatures, cracks from impact,
and pitting from spatter caused by poor maintenance will void warranty.
WELDING HELMETS DO NOT PROVIDE UNLIMITED EYE, EAR AND FACE
PROTECTION.
•Wear impact resistant safety spectacles or goggles and ear protection at all time when
using this helmet.
•Do not use this helmet for “overhead” welding, laser welding or laser cutting.
•Do not use the helmet when working with or around explosives or corrosive liquids.
WELDIND ALSO PRODUCES SOME OTHER HAZARDS SUCH AS FUME,
NOISE, SPARK, AND SPATTER. Other safety precautions are also needed.
•Wear protective clothing and footwear made from durable and flame-resistant materials.
•Provide adequate ventilation and breathing protection against welding fumes.
•Use protective screens or barriers to protect others from flash and glare.
•Warn others not to watch the arc.

SECTION 3- AUTO-DARKENING FILTER OPERATION
①DELAY ADJUSTER: Delay is used to slow the switching time from dark state
to clear state after welding. It is particularly useful in eliminating bright after-rays
present in high amperage applications where the molten puddle remains bright
momentarily after welding. The filter delay runs from 0.2 seconds to 1 second.
We recommend higher setting for higher amperage welding or for the situation
where the lens may be temporarily blocked from seeing the welding arc.
③
Stop working immediately if the filter does not turn dark when striking a welding arc.
Check all settings and solve all problems before trying again.
TEST BUTTON: The ADF filter should start working automatically.
For testing the filter prior to welding, check the external knob to make sure the filter
is not on grind mode, than face the front of the helmet to a bright source of light
and using one hand cover and uncover the sensors rapidly.
The filter should darken momentarily as the sensors are exposed.
SHADE ADJUSTMENT SWITCH: intented for choosing between din 5-9 and 9-13.
while in din 9-13 use the external knob for choosing a specific din.

5
④Sensitivity Adjuster: Sensitivity is for adjusting the filter to different light levels in various
welding process .
We recommend a Mid-range sensitivity setting for most applications. When adjusting
• Turn sensitivity level to the lowest setting;
• Increase the sensitivity until the lens darkens, and then lower it down until reaching the
level where the lens is clear. Slight readjustment may be necessary for certain application
be auto- fter 1-2 minutes to protect the lens. One only needs to adjust the sensitivity to
turn it on again.
do the following:

Shade Adjuster:
Use the Shade Guide below to select proper shade based on your welding application. We
recommend starting at Shade 13 and adjust it down according to the welding process and
personal preference.

SECTION 5 – REMOVING AND INSTALLING ADF CARTRIDGE
The cartridge is secured to the helmet by a cartridge holder with two tabs at bottom and
retainers on the top of the holder.
Removing the Cartridge: pull the external sensitivity knob out of its base and unscrew the
holding nut, then use 2 fingers to pinch the tabs at the same time and lift the cartridge from
the bottom side, next, release the cartridge from the retainers in the upper side.
Installing the Cartridge: Insert the tabs on the top to the retainers first, and then press
down the bottom of the holder and push back the retainers to click on the tabs
at the bottom, next screw the sensitivity knob back to the base.

SECTION 6 – REPLACEMENT OF COVER LENSES
Front and back cover lenses are for the protection of the auto-darkening filter. Never
use the ADF without these cover lenses properly installed. Welding spatter will damage
the auto-darkening filter and void the warranty.
Inspect the cover lenses frequently and change the damaged one (cracked, pitted,
spattered etc.) immediately.
Replacing the Front Cover lens:
Release the ADF cartridge from the retainers by repeating the process described
at SECTION 5 – removing and installing a new cartridge, take out the front cover lens.
Install the new front cover lens by reversing the above process.

10
Replacing the Back-Cover Lens: Bend the safety lens and take it
out as shown in the figure below, then slide a new lens back in.

11
SECTION 7 – REPLACMENT OF BATTERY
When upon pressing the TEST button no flashing of the filter is visible, the lithium battery
power is too low and needs to be replaced immediately
The ADF filter uses CR2032 3V LITHIUM BATTERY, to replace the battery release the
cartridge from the retainers and tabs as seen on section 5, slide the battery compartment
out. Replace the old battery with a new one. Make sure the positive end of the battery is
facing up. Slide the battery compartment back to its place, lock the cartridge back to its
place and press the TEST button. Make sure flashing of the filter is visible.

SECTION 8 – INSTALLING THE MAGNIFYING LENS
Simply insert the magnifying lens from top down as shown in the figure below, and then slide it
into the desired position in the retaining brackets.
To prevent lens fogging, install flat side of magnifying lens toward the auto-darkening filter
SECTION 9 – MAINTENANCE
Helmet and Cover Lens: Periodically clean them by using a soft cloth and a mild soap and
water solution. Allow to air dry.
ADF Filter: Occasionally clean it with a lint-free tissue or dry soft cloth or eye glass wipes.
Do NOT submerge it in water or other solut
SECTION 10 – STORAGE
The helmet should be stored in dry and well ventilated place. When stored in extreme cold
temperature, warm helmet to ambient temperature before welding.

SECTION 11 – TROUBLESHOOTING
Symptom Possible Causes Solution
Filter not responsive
Battery contact may not be good,
and/or the battery may be empty.
Check the battery; Check and
clean the battery contact;
Press the test button to make
sure the filter is functioning
Filter Not Switching
(staying light and not
darkening when
welding)
1. Obstruction of the light tothe
sensors by a dirty cover lens
1. Clean and/or replace the
cover lens; clean sensors in
front of the lens
2. The angle of the sensor to the
light is too big. If the unit isturned
away from the arc at an angle of
45 degrees or more, the unit will
not switch to dark
2. Position the filter so that the
sensors face the arc. The
optimum is a direct position in
front of the arc.
3. Airborne contaminants such as
smoke prevent the sensors from
receiving sufficient light to switch
(darken)
3. Ensure there is adequate
ventilation in the work area.
Filter Not Switching
(staying dark after the
arc is extinguished, or
no arc is present)
This may be caused by the
ambient lighting or sunlight. The
sensor is designed not to react to
sunlight but once the filter is
switched to dark, sunlight may be
bright enough to prevent it from
switching back to light state again.
Turn the filter unit away from
any source of light and/or pass
your hand in front of the
sensors briefly. Fine tune
sensitivity to lower level.
Filter is switching or
flicking
If the filter switches to dark and
then turns to light again while there
is still an arc, the sensitivity level
may not be properly selected or
there is some obstruction of light
from the arc to the sensors.
1. Increase the sensitivity
level; 2. Move the filter closer
to the arc (1-2 feet from the
arc is optimum)-but not closer.
3. Make sure that the filter is
pointed directly at the arc, and
that the sensors are not
blocked from direct exposure
to the arc (including not
blocked by your arm, welding
torch gun or nozzle); 4. Make
sure that the cover lens is
clean.

Symptom Possible Causes Solution
Lighter shaded areas
at the edge and corner
of the filter lens
The auto-darkening filter uses
liquid crystal which exhibits an
angle of view effect. In the dark
state, it is normal for welder to
notice slightly lighter shaded areas
at the edge and corners of the filter
lens. This does not represent any
health or safety hazard. The
optimum viewing angle of the auto-
darkening filter is designed to be
perpendicular to the surface of the
filter lens.
No corrective action is needed
Spots in the filter
lens. The shape and/or
spots may appear to
"grow" in the lens
It occurs after the lens has been
shut off. The liquid crystal within
the filter unit loses its electrical
polarity after the electrical current
is cut off. The liquid crystal,
therefore, "relaxes" and causes the
shape/spot to appear. It is a
normal condition, and has no
impact on the operation of the lens
No corrective action is
needed.
Partial light/shading
There appears to be a distinct
shade difference in portion of the
filter lens and there is no crack in
the unit. It may be caused by the
leakage of light in the filter unit or
reflection of light from light clothing
into the helmet or the angle of
looking through the lens, or optical
illusion caused by "visible light"
when wearing bifocals.
1. Make sure the filter unit is
properly installed; 2. Wear
dark clothing; 3. Make sure
the welding helmet is adjusted
properly so that the welder is
looking straight and directly
through the lens; 4. Welder
who wears bifocals may notice
a lighter shade in the bottom
of the filter lens. This is normal
and is optical illusion caused
by "visible light." No correction
is needed for this symptom.
Sections of the filter
not going dark,
distinctive lines
between light and dark
areas
The ADF filter may be cracked.
The crack can be caused by
dropping or hitting the helmet or by
welding spatter on the filter.
Stop welding immediately and
replace the filter if cracked.
Short Battery Life
If the batteries last only a few days
even when usage is not intense,
either the battery is wrong type or
the battery contact is not good.
Check the battery and battery
contact, make sure battery
type is CR2032
