Safety instructions
Please read the operating instructions before using the helmet. Check that the front cover lens is fitted
correctly. If it is not possible to eliminate errors, you must stop using the cartridge.
Precautions & protective restrictions
During the welding process, heat and radiation are released, which can cause damage to the eyes and
skin. This product offers protection for the eyes and face. When wearing the helmet, your eyes are always
protected against ultraviolet and infrared radiation, regardless of the shade level. To protect the rest of your
body, appropriate protective clothing must also be worn. In some circumstances, particles and substances
released by the welding process can trigger allergic skin reactions in correspondingly predisposed
persons. Materials that come into contact with skin may cause allergic reactions to susceptible persons.
The protective welding helmet must only be used for welding and grinding and not for other applications.
Optrel assumes no liability when the welding helmet is used for purposes other than intended or with
disregard for the operating instructions. The helmet is suitable for all established welding procedures,
excluding gas and laser welding
.
Please note the recommended protection level in accordance with
EN169 on the cover.
Sleep mode
The cartridge has an automatic switch-off function, which increases the service life. If no light falls on the
solar cells for a period of approx. 15 minutes, the cartridge automatically switches off. To reactivate the
cartridge, the solar cells must be briefly exposed to daylight.
If the shade cartridge cannot be reactivated or does not darken when the welding arc is ignited, the
batteries must be replaced.
Warranty & liability
Please see the instructions of the national sales organisation of Optrel for warranty provisions. For further
information in this respect, please contact your Optrel dealer.
Warranty is only granted for material and manufacturing defects. In the case of damage caused by
improper use, unauthorised intervention or through usage not intended by the manufacturer, the warranty
or liability are no longer valid. Likewise, liability and the warranty are no longer valid if spare parts other
than those sold by Optrel are used.
How to use (see cover)
1.
Head band.
Adjust the upper adjusting band (1) to the size of your head. Push in the ratchet knob (2)
and turn until the head band fits securely but without pressure.
2.
Distance from eyes and helmet angle.
By releasing the locking knobs (3), the distance between
the cartridge and the eyes can be adjusted. Adjust both sides equally and do not tilt. Then tighten the
locking knobs again. The helmet angle can be adjusted using the rotary knob (4).
3.
Automatic/manual operating mode.
The sliding switch (5) is used to set the protection level setting
mode. In automatic mode, the protection level is automatically adjusted to the intensity of the light
arc via sensors (standard EN 379:2003). In manual mode, the protection level can be set by turning
the knob (6). In the case of position welding or pulse welding with frequencies less than 10 Hz, it is
recommended to choose „manual“ mode.
4.
Protection level.
In „manual“ mode, the protection level can be set in the range DIN 9 to DIN 13 by
turning the knob (6). In „automatic“ mode, the protection level corresponds to standard EN 379, if the
rotary knob (6) is set to position „N“. Turn the knob to correct the automatically set protection level by
one protection level up or down, depending on personal preference.
5.
Grinding mode.
Press the protection level knob (7) to switch the cartridge to grinding mode. In this
mode the cartridge is deactivated and remains in light mode. The activated grinding mode is indicated
by the red flashing LED (8) inside the helmet. To deactivate grinding mode, press the protection level
knob again. After 10 minutes, the grinding mode is automatically reset.
6.
Sensitivity.
Use the sensitivity knob (10) to set the ambient light sensitivity. The red dot on the scale
corresponds to the recommended sensitivity setting in a standard situation
7.
Sensor slider.
The sensor slider can be set to two different positions. Depending on the position,
the ambient light detection angle is reduced (11-A) or increased (11-B), i.e. the cartridge reacts more
or less strongly to surrounding light sources
8.
Opening switch.
The opening switch (12) allows to select an opening delay from dark to light. „Fast“
means a delay of 0.1-0.35s and is recommended for short welding processes. If „slow“ is selected,
the delay is extended to > 0.35s. This setting should be used for long welding processes and pulse
techniques.
Cleaning
The shade cartridge and the front cover lens must be cleaned with a soft cloth at regular intervals. No
strong cleaning agents, solvents, alcohol or cleaning agents containing scouring agent must be used.
Scratched or damaged lenses must be replaced.
Storage
The welding helmet must be stored at room temperature and at low humidity. Storing the helmet in the
original packaging will increase the service life of the batteries.
Replacing the the front cover lens
Push in one side clip (13) to release the front cover lens and then remove it. Attach the new front cover
lens to one side clip (14). Pull the front cover lens round to the second side clip and clip in place. This
action requires some pressure to ensure that the gasket on the front cover lens has the desired effect.
Replacing the batteries (see cover)
The cartridge has replaceable Lithium button cell batteries, type CR2032. If you are using a welding helmet
with a fresh air connection, you must remove the face seal before replacing the batteries. The batteries
must be replaced when the LED on the cartridge (9) flashes in green.
1. Carefully remove the battery cover (15)
2. Remove the batteries and dispose of them in accordance with the national regulations for special waste (16)
3. Insert CR2032 type batteries, as shown (17)
4. Carefully replace the battery cover (18)
If the shade cartridge does not darken when the welding arc is ignited, please check battery polarity. To
check whether the batteries still have sufficient power, hold the shade cartridge against a bright lamp.
If the green LED (9) flashes, the batteries are empty and must be replaced immediately. If the shade
cartridge does not operate correctly in spite of correct battery replacement, it must be declared unusable
and must be replaced.
Removing/installing the cartridge (see cover)
1. Pull out the protection level knob (19)
2. Carefully remove the battery cover (15)
3. Unlock the cartridge retention spring as shown (20)
4. Carefully tilt the cartridge out (21)
5. Unlock the satellite as shown (22)
6. Pull the satellite out through the gap in the helmet (23)
7. Rotate the satellite by 90° and push through the hole in the helmet (24)
8. Tilt out the cartridge
The cartridge is installed in the reverse order.
