INTRODUCTION
The filter cartridge in the Variable Shade Auto-Darkening Welding
Helmet is designed for arc welding or cutting applications,
including hand welding, gas protected welding, argon arc welding
and plasma cutting.
The solar auto-darkening filter employs photoelectric sensors that
cause the liquid crystal to change from the bright state to dark
state as soon as it receives arc light. The state changes from dark
to bright shortly after the welding is finished. The delay is to
protect the eyes and face from harmful infrared or ultraviolet
radiation.

WARNING! Using filter forms from any other manufacturer’s
helmet can seriously impaired the protection provided and
may result in serious personal injury.
1. Use the correct tool for the job. This tool was designed for
a specific function. Do not modify or alter this tool or use it
for an unintended purpose.
2. This auto-darkening welding helmet is not recommended
for overhead welding applications, laser welding or laser
cutting applications.
3. In the event of electronic failure, the filter remains dark to
protect against UV and IR radiation.
4. The auto-darkening welding filter should always be used
with the original outer cover lens. Never open or tamper
with the filter cartridge.
5. Ensure the front cover lens is mounted before use and
remove protective film.
6. Ensure that the lens is clean and there is no dirt or spatter
covering the 4 sensors at the front of the filter cartridge.
7. Inspect all parts for signs of wear or damage. Any
scratched or cracked parts should be replaced prior to use.
8. Never place the helmet on a hot surface.
9. Arc rays can burn both eyes and skin. Arc welding produces
intense visible and invisible (ultraviolet and infrared) rays.
Wear a welding helmet fitted with the proper shade to
protect your face and eyes when welding or watching.
10. Check whether welding or grinding mode is chosen
before use.
11. The reaction of the Filter’s liquid crystal will be slower if
the ambient temperature is low, but it will not affect protective
functions.

ASSEMBLY & INSTALLATION
Letter references in parenthesis (A) refer to the included
Identification Key. Dashed numbers in parenthesis (Fig. 1-1)
refer to a specific point in an illustration or image.
ADJUSTING THE FIT
The headband should be adjusted both in diameter and height.
The angle between face and helmet should also be adjusted
(recommended 10° to 12°).
1. Adjust the headband diameter with
the twist knob on the back (Fig. 1-1).
The knob is locked until pushed in.
Once unlocked, twist clockwise to
tighten and counterclockwise to
loosen.
2. Adjust the height by releasing the tab
and changing the top strap hole
(Fig. 1-2).
3. Adjust the helmet to get the desired viewing angle. Loosen
the knobs (Fig. 1-3) and adjust the viewing angle when the
helmet is down. Once the angle is correct, tighten the
knobs until snug. The helmet should still swing up, but it
should not drift downward when in place for welding.
4. To adjust the distance between the user’s face and ADF,
loosen the knobs on both sides of the helmet (Fig. 1-4) until
the headband can move back and forth freely, reposition
the headband at one of the 3 slots as desired. This should
be done one side at a time and both sides should be
located at the same position for proper auto-darkening
filter operation.

OPERATION
BEFORE WELDING
1. Ensure that the internal and external protective films are
removed from the lenses.
2. Check that the batteries have sufficient power to operate the
helmet. When the battery power is low, the battery low volume
indicator LED (Q) will glow red. The filter cartridge lens may not
work correctly. Replace the batteries (see Maintenance – Battery
Replacement).
3. Check that the arc sensors are clean and not blocked by dust
or debris.
4. Check for head band tightness before each use.
SHADE NUMBER SELECTION
Manually set the shade range between 5 to 8 or 9 to 13 with the
shade switch (S). Further adjust the Shade Number with the control
knob (J). Adjust the welding helmet’s Shade Number to match the
type of welding. Consult the Welding Shade Guide to determine the
minimum shade for the amperage and welding method being
employed.
DELAY TIME
Delay time refers to the time the cartridge filter is set to change
from the dark to bright state after welding stops. The delay can
be adjusted (R) from 0.1 second up to a one-second delay.
SENSITIVITY
The sensitivity control (T) is set according to the welding process
and ambient light.
1. Low Setting - suitable for high amperage welding and
welding in areas with high levels of natural sunlight.
2. Medium Setting - suitable for most indoors and outdoors
welding.
