3. METHOD OF OPERATION
1. Assemble the mask as shown in the construction and assembly
chapter.
2. The power of the 5000 helmet is provided by solar cells with
two lithium batteries . Turning on or off is automatic controlled by
circuit. You can use this helmet at any time yon need and take it
away after working without operating any key. Using this helmet
is fully free like glass lter helmet.
3. Striking the arc, the observing window darkens immediately.
At this moment, according to the technical requirement, the
operator adjusts the darkness knob 6 in the direction as shown
by the arrow to select the optimum darkness.
4. By moving the DELAY selector knob 10 on the rear of the
cartridge, the time taken for the lens to lighten after welding can
be altered from 0.1~0.9 second.
• Turn to MIN: The time the lens lighten after welding
changes to be shorter. The shortest time is about 0.1
second depending upon welding point temperature and
shade set. This setting is ideal for track welding or
production welding with short welds.
• Turn to MAX: The time the lens lighten after welding
changes to be longer. The longest time is about 0.9
second depending upon welding point temperatare and
shade set. This setting is ideal for welding at high
amperage where there is an after glow from the weld.
5. By moving the SENSITIVITY selector knob 9 on the rear of the
cartridge, the sensitivity to ambient light changes can be altered.
• Turn to MIN: The photosensitivity changes to be lower.
• Suitable for high amperage welding and
welding in bright light conditions (lamp light
or sun light).
• Turn to MAX: The photosensitivity changes to be
higher.
• Suitable for low amperage welding and using
in poor light conditions.
• Suitable for using with steady arc process
such as TIG welding.
If the helmet can be used normally, we suggest using this helmet
with a relative high sensitivity.
6. Because the shapes of heads vary from person to person,
the work position and the observing angle is different. Therefore,
the operator may adjust the headband by adjusting button 13
and the segmental positioning plate 17 to select an appropriate
observing angle. By pushing and turning the adjustment screw
12, the perimeter of the headband can be adjusted.
4. POINTS FOR ATTENTION
1. Be sure that the helmet is be used in correct condition and
check it according to WARNING content.
2. There is liquid crystal-valve in the lter, although it has inner
and outer protection plate, it is important to avoid heavy knock
to break.
3. The outer protection plate of helmet should be periodically
inspected and cleaned, keep it clear. In case break, crack,
pitting or more serious inuencing vision effect occurs, the
plate must be replaced.
4. In order to operate more efciently and safely, please select
correct dark shade number.
5. If the lter is no water-proof model, please pay attention to
preventing from water.
6. Be sure that the arc light must be received completely by
sensor, if not, the lter will be light or unstable in darkness to
damage the person.
7. Please use the automatic lter at temperature between
-10°C-65°C (14°F-149°F )
8. Please don’t disassemble the lter, any problems arising,
please contact our company or agent.
battery, turning on or off power and any other operation.
The mask is equipped with 2 sets of photosensors to sense
arc light .In addition, the mask is also provided with an outer
protection plate made of high polymer materials. The plate is
wear-resistant, thermostable, and has no dregs-sticking, thus a
very long service life.
