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, longitu-
dinal 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 mainte-
nance. Frequency of inspections and replacement of damaged parts
is recommended.

ged or covered with welding spatter to the extent that vision is

1. Not Switching – Stop welding immediately if the auto lens stays
light and will not darken. Review the sensitivity recommenda-
tions 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.
2. Not switching – If the auto lens stays dark after the weld arc is
extinguished, or the auto-lens stays dark when no arc is pre-
sent. Fine-tune the sensitivity setting by making small adjust-
ments 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.
