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).
Safety instructions
Please read the user instructions before using the helmet. Check that the front cover lens, the head
band and the shade cartridge have been correctly fitted. The welding helmet must not be used if faults
cannot be remedied.
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,
. Please note the recommended protection level in accordance with
excluding gas and laser welding
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.
The welding helmet must not be used for overhead welding, as there is a risk of injury
due to falling molten metal.
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 cartridge cannot be reactivated
or does not darken when the welding arc is ignited, it must be regarded as non-functional and 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.
Usage (see Quick Start Guide)
1. Head band. Please adjust the upper adjusting strap (p.4 No.1) to your head size. Depress ratchet
knob (p.4 No.1) and rotate until the head band sits firmly yet comfortably.
2. Eye distance and helmet inclination. The distance between the cartridge and the eyes is adjusted by
releasing the locking knobs (p.4-5 No.2). Adjust to the same extent at both sides without jamming.
Then retighten the locking knobs. The helmet inclination can be adjusted using the rotary knob (p.5
No.3).
3. Shade level. The shade level can be selected between 9 and 13 by rotating the shade level knob (p.8).
4. Sensitivity. With the sensitivity button the light sensitivity is adjusted according to the welding arc
and the ambient light (p.8). The middle position corresponds to the recommended sensitivity setting
in a standard situation.
5. Opening delay. The opening delay knob (p.8) allows the opening delay to be set continously from
dark to light. It is adjustable within a range of 0,05 to 1,0 seconds. The middle position corresponds
to the recommended delay in a standard situation.
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 with low air humidity. Storing the helmet in
the original packaging will increase the service life of the batteries.
Replacing the front cover lens (see p.4-5 No.5)
1. Hold the wing of the front cover lens
2. Push the lens against the opposite side of the holding frame
3. Remove the lens sidewards
4. Hold the wing of the new front cover lens
5. Push the lens against the opposite side of the holding frame
6. Insert the lens into the holder
Replacing the batteries (see p.5 No. 4)
The shade cartridge has replaceable lithium button cell batteries, type CR2032. The batteries must be
replaced when the LED on the cartridge f lashes in red.
1. Carefully remove battery cover
2. Remove batteries and dispose of in accordance with the national regulations for special waste
3. Use type CR2032 batteries as depicted
4. Carefully remount 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
red 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 shade cartridge (see p. 6)
1. R emove potentiometer knob as depicted and undo nut
2. Release cartridge retaining spring as shown
3. Carefully tip out the cartridge
The shade cartridge is installed in the reverse order.
Troubleshooting
Shade cartridge does not darken
→ Adjust sensitivity
→ Clean sensors and front cover lens
→ Check flow of light to the sensors
→ Replace batteries
Shade cartridge flickers
→ Adjust sensitivity
→ Replace batteries
Poor vision
→ Clean front cover lens and shade cartridge
→ Adapt shade level to welding procedure
→ Increase amount of ambient light
Weldinghelmet slipping
→ Readjust / tighten head band
