Introduction
A welding helmet is a type of headgear used when performing certain types of welding to protect
the eyes, face and neck from flash burn, ultraviolet light, sparks, infrared light, and heat. The helmet
consists of several parts (see spare parts list). An automatic welding filter combines a passive UV and
a passive IR filter with an active filter, the luminous transmittance of which varies in the visible region
of the spectrum, depending on the irradiance from the welding arc. The luminous transmittance of the
automatic welding filter has an initial high value (light state). After the welding arc strikes and within
a defined switching time, the luminous transmittance of the filter changes to a low value (dark state).
Depending on the model, the helmet can be combined with a protective helmet and / or with a PAPR
(Powered Air Purifying Respirator) system.
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 / Risks
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. The manufacturer 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 in the manual. Scratched or damaged lenses must be
replaced. The helmet does not replace a safety helmet. Depending on the model, the helmet can be
combined with a protective helmet.
The helmet can affect the field of view due to constructive specifications (no view on the side without
turning the head) and may affect a color perception due to the light transmission of the auto darkening
filter. As a result, signal lights or warning indicators may not be seen. Further there is an impact hazard
due to a larger contour (head with helmet on). The helmet also reduces the audio and heat perception.
Sleep mode
The cartridge has an automatic switch-off function, which increases the service life. If the light
falls on the catridge for a period of approx 10 minutes less than 1 Lux, it automatically switches
off. To reactivate the cartridge,it 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 General Terms of Delivery and Payment of the national Fronius sales organisation
for the warranty provisions. Further information is available from your authorised specialist dealer.
The warranty covers material defects only. All warranty and liability provisions shall become void
in the event of improper use. Failure to use original spare parts will also invalidate the warranty and
liability. Wearing parts are excluded from the warranty.
Expected Lifetime
The welding helmet has no expiration date. The product can be used as long as no visible or invisible
damage or functional problems occur.
How to use (Quick Start Guide)
1. Head band. Adjust the upper adjusting band (p. 4) to the size of your head. Push in the ratchet
knob (p. 4) and turn until the head band fits securely but without pressure.
2. Distance from eyes and helmet angle. By releasing the locking knobs (p. 4-5), 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
(p. 5).
3. Automatic/manual operating mode. The sliding switch (p. 6) 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 (p. 6-7).
4. Shade Level. In "manual" mode, the protection level can be set by the range slider between
the range level SL5 to SL9 and SL9 to SL13. The fine adjustment can be set by turning the
potentiometer knob (p. 6-7). In "automatic" mode, the protection level (SL5 – SL13) corresponds
to standard EN 379, if the potentiometer knob (p. 6-7) is set to position "N". Turn the knob to
correct the automatically set protection level by two protection levels up or down, depending on
personal preference.(green inscription)
5. Grinding mode. Press the Grind button (p. 6) 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 (p. 6) inside the helmet. To deactivate grinding mode, press
the protection level knob again.After 10 minutes, the grinding mode is automatically reset.
6. Sensitivity. With the sensitivity button the light sensitivity is adjusted according to the welding
arc and the ambient light. The border of the "Super High" area is the standard sensivity setting.
By turning the knob, these can be customized. In the "Super High" area the maximum light
sensitivity can be achieved.
7. Sensor slider. The sensor slider can be set to two different positions. Depending on the position,
the ambient light detection angle is reduced (p. 7) or increased (p. 7).
8. Delay switch. The opening knob (Delay) (p. 7) allows to select an opening delay from dark to
light. The knob allows infinite adjustment from dark to light between 0.1 to 2.0 s which protects
the eyes.
Cleaning and disinfection
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 (p. 8-9)
Push in one side clip to release the front cover lens and then remove it. Attach the new front cover
lens to one side clip. 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 (p. 5)
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 flashes in green.
1. Carefully remove the battery cover
2. Remove the batteries and dispose of them in accordance with the national regulations for special waste
3. Insert CR2032 type batteries, as shown
4. Carefully replace the battery cover
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 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 (p. 8)
1. Pull out the protection level knob
2. Carefully remove the battery cover
3. Unlock the cartridge retention spring as shown
4. Carefully tilt the cartridge out
5. Unlock the satellite as shown
6. Pull the satellite out through the gap in the helmet
7. Rotate the satellite by 90° and push through the hole in the helmet
8. Remove / replace the shade cartridge
The cartridge is installed in the reverse order.
