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 on page 10. 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. Shade Level. The shade level can be changed by turing the knob from shade
level SL 8- SL 12 according to standard EN 379 (p.6-7),
4. 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 shade
level SL 2.5. The activated grinding mode is indicated by the red flashing LED
(p. 6) inside the helmet. To deactivate grinding mode, press the Grind button
level knob again. After 10 minutes, the grinding mode is automatically reset.
5. Sensitivity. With the sensitivity button the light sensitivity is adjusted according
to the welding arc and the ambient light. The middle position corresponds to the
recommended sensitivity setting in a standard situation. In the "Super high"
range the maximum light sensitivity can be achieved.
6. Sensor slider. The sensor slider can be set to two different positions. Depending
on the position, the ambient light detection angle is reduced or increased.
7. Delay switch. The opening knob (Delay) allows to select an opening delay from
dark to light. The knob allows infinite adjustment from dark to light between 0.05
to 1.0 s.
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
Troubleshooting
Cartridge does not darken
→ Adjust sensitivity
→ Clean sensors or front cover lens
→ Check the light flow to the sensor
Protection level too bright
→ choose a lower shade level
Protection level too dark
→ choose a higher shade level
Cartridge flickers
→ Adjust position of the delay knob on welding procedur
→ Replace the batteries
Poor vision
→ Clean the front cover lens or cartridge → Increase the ambient light
→ Adjust the protection level to the welding procedure
Welding helmet slips
→ Adjust/tighten the head band
