Sensitivity Selection
•
Press the
B - Function
button to select “SENSITIVI
-
TY”. Use the
D - Up / Down
buttons to adjust the sensi
-
tivity to ambient light.
Both in welding and cutting mode the sensitivity
range can be set from 0 to 10. It is not adjustable in
Grinding mode. (Fig. 3-4-5)
By a low setting the photosensitivity changes to be lo
-
wer. Suitable for welding in bright light conditions (lamp
light or sun light).
By a high setting 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 bit
high sensitivity.
Both in welding and cutting mode, to meet the
needs of special applications, if the sensitivity ran-
ge is set to 10 the filter will always remain dark and
won’t automatically turn off after 30‘ of inactivity.
Delay Time Selection
•
Press the
B - Function
button to select “DELAY”.
Use the
D - Up / Down
buttons to adjust the delay time,
the time taken for the lens to lighten after wel-
ding.
Both in welding and cutting mode the delay range
can be set from 0 to 10 (0.1 to 1.0s). It is not adju-
stable in Grinding mode. (Fig. 3-4-5)
By a low setting 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 tack welding or
production welding with short welds.
By a low setting the time the lens lighten after welding
changes to be longer. The longest time is about 1.0s
depending upon welding point temperature and shade
set. This setting is ideal for welding at high amperage
where there is an after glow from the weld and for low
current TIG welding in order to avoid the filter opening
when the light to the sensors is obstructed by the ope
-
rator’s hand, by the torch, etc.
Battery Indicator (Fig.6)
The symbol E is the battery status indicator. The char-
ge has four levels indicated by the indicator. When the
symbol
appears, 1-2 days of charge remain. Re-
place the batteries in time.
The symbol does not update in real time, it has to
be updated by pressing the A - On / Mode button.
•
Quick press the
A - On / Mode
button to check whe
-
ther the filter is working correctly and to set the darke
-
ning level, the delay time and the sensitivity.
•
Press and hold the
A - On / Mode
button to turn off
the filter and return to the clear state.
•
The filter will automatically turn off after half an hour
of non-use.
Note: if the sensitivity level is set to 10, the filter
will NOT turn off automatically.
Do not use the welding helmet if the filter does not
work as described above.
Operating Mode (Fig.2)
•
Quick press the
A - On / Mode
button to select the
appropriate mode for your activity:
WELD Mode
•
In the welding mode the shade function is turned
on when it optically senses a welding arc. Select
shade level, delay time and sensitivity according to
your needs as described below
.
CUTTING Mode
• In the cutting mode the shade function is turned
on when it optically senses a cutting arc. Select
shade level, delay time and sensitivity according to
your needs as described below
.
GRIND Mode
• In the grinding mode the shade function is turned
off. The shade is fixed to shade DIN 4 allowing a cle
-
ar view to grind a weld with the helmet providing face
protection. Warning: do not use the helmet in grin
-
ding position for any other application than grinding.

requirements, select the optimal degree of protection.
The darkening range varies according to the mode set
(Fig. 3-4-5).
