INTRODUCTION
Your automatic welding helmet is a new generation
product for labour protection. Some new and high
sciences and technologies such as LCL, optoelectro-
nics detection, solar power, microelectronics, etc are
integrated into it. The automatic welding helmet not
only can efficiently protect operator's eyes from injuri-
es caused by arc, but also can make both hands free
and strike arc accurately. Therefore, the quality of pro-
ducts and work efficiency may be raised considerably.
It may be widely used for various welding, cutting, grin-
ding and arc gouging, etc.
SAFETY WARNING
Read and understand all instructions before using.
• Be sure that the dark shade number of the lens set in
the welding filter is the correct shade for your application.
• These helmets and filters are not suitable for
"overhead" welding application, laser welding or laser
cutting applications.
• These welding helmets are designed to protect eyes
and face from sparks, spatters and harmful radiations
under normal welding conditions. They will not protect
against severe impact hazards. Pay particular attention
when using the welding helmet for grinding.
•
These welding helmets will not protect against
explosive devices or corrosive liquids. Machine guards
or eye splash protection must be used when these
hazards are present.
• Impact resistant, primary eye protection, spectacles
or goggles that meet current ANSI specifications, must
be worn at all times when using this welding helmet.
• Avoid work positions that could expose unprotected
areas of your body to sparks, spatters, direct and/
or reflected radiations. Use adequate protection if
exposure cannot be avoided.
• Avoid hard blows that may damage the filter.
• Check for light tightness before each use. Before each
use, check that the protection plates are clean and that
no dirt is covering the sensors on the front of the lens.
• Inspect all operating parts before each use for signs
of wear or damage. Any scratched, cracked, or pitted
parts should be replaced immediately.
• Do not make any modifications to either the welding
lens or helmet, other than those specified in this manual.
• Do not use any replacement parts either than those
specified in this manual. Unauthorized modifications
and replacement parts will void the warranty and
expose you to the risk of personal injury.
• If this lens does not darken when striking the arc,
stop welding immediately and contact your dealer or
service centre.
• Do not immerse this lens in water and keep it away
from dust.
• Do not use solvents on any lens or helmet's
components.
• The recommended operating temperature is -10°C
e 55°C (14°F-131°F). Do not use this device beyond
these temperature limits.
• Be sure that the arc light is received completly by
the sensors, if not, the filter will be light or unstable in
darkness. This may be dangerous to you.
• Do not disassemble the filter, any problems arising,
please contact your dealer or service centre.
• Do not leave the workplace with the welding helmet
in the lowered position; a bright light source could
cause the filter to darken unexpectedly.
• Failure to follow these warnings and/or failure to
follow all of the operating instructions could result in
severe personal injury.
FEATURES
Your welding helmet is equipped with a filter set that
can become dark. The filter is transparent before wel-
ding, so you may observe the work surface clearly.
When striking the arc, the filter darkens automatically
immediately. When arc goes out , the filter will become
transparent again. The switching time from light to dark
is about 0.00004 seconds. The switching time from
dark to light may be set up within 0.1 to 1.0 seconds.
The mask is equipped with digital darkness-adjusting
unit, so you may select an arbitrary dark shade number
ranging from number 9 and number 13 for welding ap-
plication and from number 5 to 8 for cutting application.
The welding helmet gives you permanent and com-
plete protection against UV/IR even in transparent
condition. The UV/IR protection level is up to DIN16 in
all time. The power is provided by solar cells and two
CR2450 batteries. The mask is equipped with 4 sets of
photosensors to sense arc light. In addition, the helmet
is also provided with an outer protection plate made of
high polymer materials.
The plate is wear-resistant, thermostable, and has no
dregs-stricking, thus a very long service life.
METHOD OF OPERATION
Assembly
• Assembly: Assemble the helmet as shown in the
assembly drawing.
Power Supply
• The power is provided
by solar cells with two
CR2450
batteries.
Remove

two
CR2450
batteries
making sure the anode
and cathode of the battery
are
correctly
installed.
Reinstall
