Before Welding - 3M Speedglas 100 Instrucciones De Uso

3M™ Speedglas™ 100
Welding Shield

BEFORE WELDING

For your own protection read these instructions carefully
before using the Speedglas 100 welding shield.
The complete assembly is illustrated in figure A:1.
Adjust the welding shield according to your individual
requirements to reach the highest comfort. (see figure
B:1-B:3).
Shade number should be chosen according to table (see
figure H:1).
The Speedglas 100 welding shield gives permanent
protection (shade 12 equivalent) against harmful UV- and
IR-radiation, regardless of whether the filter is in the light
or dark state or whether the auto-darkening function is
operational.
Two lithium batteries are used as the power source (3V
CR2032).
WARNING!
• When used in accordance with these user instructions,
this product is designed to help protect the wearer's eyes
and face from harmful radiation including visible light,
ultra-violet radiation (UV), infrared radiation (IR) and
sparks and spatter resulting from certain arc welding
processes.
• Use of this product in any other application such as
laser welding/cutting or gas welding/cutting may result
in permanent eye injury and vision loss.
• Do not use any welding product without appropriate
training. Read instructions before use.
• Use only with original Speedglas brand spare parts such
as inner and outer protection plates according to the
part numbers provided in these instructions. The use of
substitute components or modifications not specified in
these user instructions might impair protection and may
invalidate claims under the warranty or cause the shield
to be non-compliant with protection classifications and
approvals.
• The Speedglas 100 welding shield is not designed for
overhead welding/cutting operations when there is a risk
of burns from falling molten metal.
• The manufacturer is not responsible for any modifications
to the welding filter or use with welding shields other than
the Speedglas 100 welding shield. Protection may be
seriously impaired if unsuitable modifications are made.
• Wearers of ophthalmic spectacles should be aware that
in the case of severe impact hazards the deformation of
the shield might cause the inside of the shield to come
into contact with the spectacles creating a hazard for the
wearer.
APPROVALS
Speedglas 100 has been shown to meet the Basic Safety
Requirements under Article 10 of the European Directive
89/686/EEC and is thus CE marked. The product complies
with the harmonized European Standards EN 175, EN 166,
EN 169 and EN 379. The product was examined at the
design state by DIN Certco Prüf- und Zertifierungszentrum
(Notified body number 0196).
MARKINGS
The welding filter is marked with the shade range and
optical classifications.
The following is an example (EN 379):
3 / 8 -1 2 3M 1 / 2 / 2 / 3 / EN379 CE
Light shade
Dark shade(s)
Manufacturer identification
Optical class
Diffusion of light class
Variations in Luminous transmittance class
Angle dependency class
Certification mark or number of standard
Note! The above is an example. Valid classification is
marked on the welding filter.
3M 1BT (EN166 medium energy impact at extremes of
temperatures (-5°C and +55°C) BT)
3M EN175B (medium energy impact B)
The markings on the welding shield and the protection
plates, indicate safety class for protection against high
speed particles. S stands for the basic requirement for
increased robustness, F stands for low energy impact and
B stands for medium energy impact.
If the protection meets the requirements at extremes of
temperature (-5°C to +55°C) the marking is completed with
the letter T. Additional markings on the product refer to other
standards.

FUNCTIONS
ON/OFF
To activate the welding filter, press the ON/SHADE button.
The welding filter automatically turns OFF after 1 hour of
inactivity.
The welding filter has two photo sensors (see fig A:2) that
react independently and cause the filter to darken when a
welding arc is struck. The welding filter may not go to dark
position if the sensors are blocked or the welding arc is
totally shielded.
Flashing light sources (e.g. safety strobe lights) can
trigger the welding filter making it flash when no welding is
occurring. This interference can occur from long distances
and/or from reflected light. Welding areas must be shielded
from such interference.
SHADE
Models Speedglas 100S-10 and Speedglas 100S-11 have a
fixed dark shade where no setting is required.
Model Speedglas 100V has selectable dark shade settings.
Five different Shade Number settings, 8-12, are available
in the dark state. In order to see the current Shade Number
setting, momentarily press the ON/SHADE button. To
select another Shade Number, press the ON/SHADE
button repeatedly while the LED indicators on the display
are flashing. Move the flashing LED to the desired Shade
Number.
In all welding processes the arc should only be viewed with
the recommended dark shade. See table page 77.
