Exposure to welding or cutting exhaust
fumes can increase the risk of developing
certain cancers, such as cancer of the
larynx and lung cancer. Also, some
diseases that may be linked to exposure
to welding or plasma cutting exhaust
fumes are:
• Early onset of Parkinson’s Disease
• Heart disease • Ulcers
• Damage to the reproductive organs
•Inammationofthesmallintestineor
stomach • Kidney damage
• Respiratory diseases such as
emphysema, bronchitis, or pneumonia
Use natural or forced air ventilation and
wear a respirator approved by NIOSH to
protect against the fumes produced to
reduce the risk of developing the above
illnesses.

to help ensure reliable protection:
a. Clean filter’s surfaces regularly. Keep sensors
and solar cells clean using a clean lintfree tissue/cloth. Do not use any solvents
on filter’s screen or helmet components.
Protect filter from liquid and dirt contact.
Do not immerse the filter in water.
b. Should the Auto-Darkening Welding Helmet
not darken upon striking an arc, stop
welding immediately and have the helmet
checked by a qualified service technician.
c. Regularly replace the Front Lens Cover
if it becomes cracked, scratched,
pitted, or otherwise damaged.
d. Do not make any modifications to either the
Auto-Darkening Filter or the rest of the helmet,
other than those specified in this manual. Do
not use any replacement parts other than
those specified in this manual. Unauthorized
modifications and replacement parts will
void the warranty and expose the user to
the risk of personal injury. Do not open or
tamper with the Auto-Darkening Filter.

The Auto-Darkening Welding Helmet is designed to protect the eyes and face from sparks, splatter, and
harmful radiation under normal welding conditions. The Auto-Darkening Filter automatically changes from
a clear state to a dark state when an arc is struck, and it returns to the clear state when welding stops.

This Welding Helmet utilizes high performance solar cells as its power supply, and has a replaceable 3V CR2450
lithium battery as power backup. Refer to Maintenance section for battery replacement information.

User-selectable variable shades from 5 to 8 and 9 to 13 are adjusted with the Shade Range
Switch and Shade Control Knob (shade variable). This product is in full conformity with
related DIN, ISO, EN379 safety standards and ANSI Z87.1-2010 standard.
<"7$*(#
The ultra high performance of UV and IR Auto-Darkening filters provides the user’s eyes
and face with full protection against UV and IR radiation during the entire welding process,
even in clear state. The UV/IR protection level is up to shade 16 at all times.

The Auto-Darkening Welding Helmet comes ready
for use. Prior to first use, remove the protective film
from both sides of the Front Lens Cover and Inside
Lens Cover (if not already done). Check the Front
Lens Cover to make sure that it is clean, and that
no dirt is covering the four sensors on the front of
the Auto Darkening Filter Cartridge. Also check the
Inside Lens Cover and the Lens Retaining Frame,
and make sure that they are secured in place.
C5/&($,8$- Helmet is shipped without Battery installed.
Before first use install the CR2450 Lithium Battery
included with the Helmet. Refer to Battery Installation
or Replacement on page 10 for instructions.
Adjust the position of the headband, select the correct
shade number for the welding application, and test
the helmet for proper operation as described below.
Inspect all operating parts before each use for signs
of wear or damage. Any scratched, cracked, or
pitted parts should be replaced immediately before
using again to avoid severe personal injury.

1. Use the Mode Switch to select the mode of
operation. Make sure the correct mode is selected
for your application. Refer to Figure B and Figure C.
• Set the switch to Weld Mode for welding
applications. In this mode the Auto-Darkening
Filter automatically changes from a clear state to
a dark state when an arc is struck. Select shade
level, time delay and sensitivity as required.
• Set the switch to Grind Mode for grinding
applications. This turns off the shade function
so the helmet lens stays clear. Use this
function to provide protection while grinding.

select the shade range required using the
Shade Range Switch, then turn the Shade
Control Knob to the shade number required.
E&$*- If a selection of shades are recommended
for your application, try the darkest setting first.
3. The shade number can be set from 5 to 8 (cutting)
or from 9 to 13 (welding) depending on the
shade range selected. Turn the Shade Control
Knob until the arrow points to the desired shade
number. Be sure that the shade number of the
Welding Helmet is the correct shade number for
your application. Refer to Figure B and Figure C.
4. Remember to check with the Shade Guide
Chart on page 5 to determine the proper
shade number for your application.
C5/&($,8$- Test the helmet auto-darkening filter lens
before welding. Press and hold the TEST Button on
the Auto-Darkening Filter Cartridge
to preview the selected shade
number. When the Button is
released the lens will return to the
resting state (#3 Shade). If the lens
does not darken properly, replace the Battery and try
again. Do not use the Welding Helmet if it is not
operating correctly.

1. At the moment the welding operation is started,
the filter screen automatically changes from clear
to dark. The operator can vary the amount of time
it takes the filter to return to a clear state after
welding stops using the Time Delay Control Knob.
2. Use the Time Delay Control Knob to set the
delay time between 0.1 second ("S" short) and
1.0 second ("L" long).
3. The sensitivity setting changes the amount
of light needed to make the filter react. The
sensitivity of the sensors can be adjusted
using the Sensitivity Control Knob.
4. Use the Sensitivity Control Knob to set the sensitivity
between low ("LO") and high ("HI").

Adjust the Headband so that the Helmet is seated
securely on your head as low as possible and close
to your face using the following procedure:
a. Adjust the Headband width by turning
the Headband Adjustment Knob while
wearing the Helmet to make sure the Front
Lens Cover is aligned with your eyes and
the Helmet fits firmly on the head.
b. Adjust the Headband height by tightening
or loosening the Top Straps until the
Helmet fits snug on your head.
c. Adjust the distance between the front of
the Helmet and your face by loosening the
Tension Adjustment Knobs and sliding the
Headband harness forward or back.
d. To adjust the tilt angle, loosen the right Tension
Adjustment Knob and push the top of the Angle
Adjustment Lever outward until the Lever’s
stop tab clears the notches. Rotate the Lever
forward or back to the desired position, then
release the Lever to engage the stop tab.
e. Once the Headband is properly adjusted,
lower the Helmet over your face until the
proper angle is found. Then turn the Tension
Adjustment Knobs on either side of the
helmet, locking the helmet’s angle in place.
