SAFETY WARNINGS
– READ BEFORE USING
WARNING
Read & Understand All Instructions Before Using
Auto-Darkening welding helmets are designed to protect the eye and face from
sparks, spatter and harmful radiation under normal welding conditions. The
Auto-Darkening filter works automatically.
It changes from light to dark state when the welding arc is struck, and it
returns to the light state when welding stops.
The Auto-Darkening welding helmet comes assembled. However before it can be
used, it must be adjusted to your personal preferences.
Set it up for delay time, sensitivity and shade number for your application.
The helmet should be stored in a dry, cool and dark area and remember to
remove the battery before long-time storage.
WARNING
- This Auto-Darkening welding helmet is not suitable for laser welding or oxy-acetylene (gas welding) applications
- Never place the helmet and Auto-Darkening filter on a hot surface.
- Never open or tamper with the Auto-Darkening filter.
- This Auto-Darkening welding helmet will not protect against severe impact hazards.
- This helmet will not protect against explosive devices or corrosive liquids.
- Do not make any modifications to either the filter or helmet, unless specified in this manual.
- Do not use replacement parts other than those specified in this manual. Unauthorized modifications and replacement parts will void the warranty and expose the operator to the risk of personal injury.
- Should this helmet not darken upon striking an arc, stop welding immediately and contact your supervisor or your dealer.
- Do not immerse the filter in water.
- Do not use any solvents on the filter screen or helmet components.
- Use only at temperatures: – 5 °C ~ +55 °C (23 °F ~ 131 °F).
- Storing temperature: -20 °C ~ +70 °C (- 4 °F ~ 158 °F). The helmet should be stored in a dry cool and dark area, when not using it for a long time.
- Protect the filter from contact with liquid and dirt.
- Clean the filter surface regularly; do not use strong cleaning solutions. Always keep the sensors and solar cells clean using a clean lint-free tissue.
- Regularly replace the cracked / scratched / pitted front cover lens.
- The materials which may come into contact with the wearer’s skin can cause allergic reactions in some circumstances.
- The ADF shall only be used in conjunction with the inner cover lens.
- Wear approved safety glasses with side shields under your helmet.
- Eye-protectors against high speed particles worn over standard ophthalmic spectacles may transmit impacts, thus creating a hazard to the wearer.
- Toughened mineral filter oculars shall only be used in conjunction with a suitable backing ocular.
- If the symbols F or B are not common to both the ocular and the frame, then it is the lower level which shall be assigned to the complete eye-protection.
INSTRUCTIONS FOR USE
WARNING! Before using the helmet for welding, ensure that you have read and
understood the safety instructions
Information manual for the Böhler Welding protective helmets comply with Para 1.4 of Appendix II of the PPE Regulations (EU) 2016/425. Böhler Welding helmets offers permanent protection against UV/IR rays, also face and eye protection against sparks caused by the welding process.
Do not look directly into the welding arc with unprotected eyes when the arc strikes. This can cause painful inflammation of the cornea and irreparable damage to the lens of the eye leading to cataracts.
RANGE OF APPLICATION
WARNING! Before using the helmet for welding, ensure that you have read and
understood the safety instructions.
Böhler Welding helmets and welding filters can be used for most arc welding
applications and for GTAW / TIG where stated. The welding filters provide
protection against harmful UV- and IR-radiation according to the requirement
for shade number marked on each passive of automatic (ADF) model; eye
protection remains as long as the flip up is in the down position covering the
vision.
The following chart is presented as a reference for the selection of the most
suitable shade for the welding filter: (p. 6)
Depending upon the application conditions, the next highest or next lowest
protection level can be used.
The darker fields indicate those areas in where the corresponding welding
process cannot be used.
Böhler Welding helmets are suitable for, but not limited to the following
applications:
ʷ AC/DC pulses
ʷ Inverters WIG/TIG
ʷ Stick welding
ʷ Argon/Helium
ʷ MIG/MAG protective gas electrodes
PREPARATION & OPERATION
Böhler Welding helmets are fully assembled and ready to be used after minor
adjustments. All welding helmets are equipped with a comfortable headgear that
can be adjusted for comfort: (p. 7)
Rotate the adjustment knob at the rear of the headgear assembly to fit the
user‘s head. There is adjustment on the top strap, longitudinal adjustment and
angular adjustment.
Before commencing work please inspect carefully the welding helmet and ADF for any visible marks, cracks, pitted or scratched surfaces; damaged surfaces even on protection plates reduce vision impair protection. If protection plates are scratched, damaged or built up with spatter please replace.
Welding helmets should not be dropped. Do not place heavy objects or tools on
or inside the helmet as they might damage the components.
If used with care, the welding filter requires no further maintenance during
its lifetime.
SERVICING AND MAINTENANCE
Only clean the helmet with mild soap and water. Dry with a clean cotton cloth. The use of solvents is strictly prohibited, as they will damage the mask and filters. Scratched or damaged visors must always be replaced.
The user must make daily regular checks to ensure no damage is evident. Outer and inner visors are wear parts and must be replaced regularly with genuine certified universal spare parts.
We recommend a use period of 3-4 years. The duration of use depends on various
features such as useage, cleaning, storage and maintenance.
Frequency of inspections and replacement of damaged parts is recommended.
REPLACING THE OUTER LENS
- Ensure that the helmet is always fitted with Böhler Welding approved outer and inner protection lens.
- The protection lenses must be replaced when broken, damaged or covered with welding spatter to the extent that vision is impaired.
- Outer and Inner protection lenses are wear parts and must be replaced regularly with genuine certified spare parts.
- The outer protection lens is mounted from the back, see illustration. (p. 7)
- The inner lens is mounted from the back into the locaters on the auto darkening filter. Protection marked in accordance with this standard is only provided when all lens and retention components are installed according to the list of manufactures instructions.
- Change dark shade from 9 to 13 to 5 to 9 or to Grind mode as desired on the ADF. (p. 6)
- Adjust the Sensitivity Time as desired by using the variable adjustment knob. (p. 6)
- The Delay Time (from dark to light) is adjsted with the right toggle on the ADF (p. 6) . There are 3 delay settings to choose: „SLOW“ 0.9 sec., „MID“ 0.5 sec. and „FAST“ 0.1 sec.
- The delay is adjusted on the left hand toggle switch there are 3 delay settings to choose from Top Slow delay 0.9sec middle medium delay 0.5sec and bottom fast delay 0.1sec
- When the helmet is not used for 15 minutes the power will automatically shut-off. There is no OFF switch.
REPLACING THE ADF BATTERY
It is essential that when replacing the battery that it is mounted the correct way up as per the illustration. (p. 6)
TROUBLE SHOOTING
- Not Switching – Stop welding immediately if the auto lens stays light and will not darken. Review the sensitivity recommendations and adjust sensitivity. Clean lens cover and sensors of any obstructions. Note! Make sure the sensors are clean and facing the arc; angles of 45° or more do not allow the arc light to reach the sensors.
- Not switching – If the auto lens stays dark after the weld arc is extinguished, or the auto-lens stays dark when no arc is present. Fine-tune the sensitivity setting by making small adjustments to the control by turning it toward the ‘Lo’ setting. In extreme light conditions, it may be necessary to reduce the surrounding light levels.
During testing or use, in case of any malfunctioning, please suspend using it and contact your local sales agent.
