Helmet-to-face distance adjustment:
To adjust this distance, unscrew mounting nuts
and put the screws
C
through square holes
in headgear frame to move the helmet closer to
D
or further from the face. When the right distance is set, tighten the nuts .

NOTE!
Perform the adjustment for both sides of the helmet. The smallest

Helmet angle adjustment
If helmet angle is not right for the operator, it may be adjusted:
–
Loosen mounting screws .
C
–
Change helmet angle.
–
Tighten mounting screws .

CAUTION!
The correct helmet angle protects against spatter and radiation

8. USE:
n
Helmet power source
The helmet is powered with two lithium CR2
3 V batteries charged by
032
solar cells. It provides battery life of 5000 hours under normal operating
conditions.
Filter power is automatically controlled by optical sensors.
The internal control panel has the TEST button, which can be used to
control correct operation of helmet systems (the operation mode switch
should be set to welding), and an LEDy indicator for empty batter. The
low voltage diode is off when power provided to the filter is sufficient.
When the diode is on, the batteries should be replaced.
n
Helmet shade selection:
Find the right shade for your welding
process in the table on page
and set the
4
operation mode and shade knob
(see Fig
5
C
9–13
) to the appropriate position
.
D uring grinding, set the knob
to
5
SZLIFOWANIE/GRIND
and turn off the
shade.
n
Setting sensitivity and clearing time after welding:
Upon welding, the filter automatically switches from clear to dark in
1/25,000 s.
Stepless regulation of filter sensitivity to electric arc can be set with the
CZUŁOŚĆ/SENSITIVITY
HI
knob on the filter cartridge. Higher settings (
)
are recommended for low currents or TIG welding; lower values (
) are
LO
recommended for high currents or MIG/MAG welding.

OPÓŹNIENIE/DELAY
knob located on the filter cartridge near the
CZUŁOŚĆ/SENSITIVITY
knob. With this knob, you can set the filter
reaction time between 0.1 s and 1.0 s.
The delay compensates for afterglow on the workpiece. MIN (minimum
delay), MAX (maximum delay).
9.TROUBLESHOOTING:
1. Erratic shading
a)
The headband was set incorrectly and the eye-to-filter distance
varies (readjust the headband to rectify the difference in the
distance).
2. The auto darkening filter does not get dark or it flickers.
a)
The front glass is dirty or damaged
.
(cleanorreplace)
b)
Sensors are dirty
(cleansensors).
c)
Welding current too low
.
(setthesensitivityswitchtoMAX)
d)
Batteries are empty
.
(replace batteries)
3. Slow reaction
a)
Too low operating temperature
(do not use the helmet below -
5°C)
.
4. Poor vision
a)
Front/internal glass and/or filter dirty
.
(cleanorreplace)
b)
Insufficient lighting
.
(provideadequatelighting)
c)
Incorrect filter shade set
(check the recommended shades specified
inthismanualandsetthecorrectone)
.
5. The helmet slides off my head
a)
The headband is not adjusted correctly
.
(readjust)
10. MAINTENANCE AND STORAGE:
Perform careful maintenance on the helmet on a regular basis. It will
keep it in a good condition.
The product should be stored in provided unit packaging in a dark, dry,
ventilated, and locked room. Store in temperatures of -20° C to +70° C.
Protect the product against dust, particulate, and other contaminants
(foil bags etc.). Protect against mechanical damage. Transport in the
provided unit packaging, in boxes, in closed vehicles.
n
Cleaning
Clean the filter with a clean and soft cloth or cotton.
Do not submerge the helmet and filter in water. Never use abrasive
substances, solvents, or oil-based detergents.
Do not open the filter cartridge by yourself. The filter cartridge may be
disassembled by authorised service or qualified technician. Otherwise
the warranty is rendered void.
n
Replacing the protective glass:
In order to ensure long and fault-free operation of the filter, it is
forbidden to use the helmet without polycarbonate protective glasses.
Replace the front protective glass on a regular basis. Hitting spatter
tarnishes it, which is a natural phenomenon.
In order to replace the protective glass, remove the auto darkening filter
cartridge and pull the glass towards the inside of the helmet.
CAUTION!
The filter element should be replaced and installed by qualified
andcompetentpersonnelonly.
n
Replacing the filter batteries
If the LOW BATTERY diode is on, replace the batteries with new ones.
The batteries are located in two independent compartments in the filter
cartridge. In order to replace the batteries, rotate and remove a
compartment lid. Remove a used battery and put a new one in.
Close the lid and repeat for the other battery.
CAUTION!
Replace the batteries only in twos. Do not use a used and new
batteryatthesametime.
