3M Speedglas 9100 Welding Shield
The difference
is clear
of welders worldwide
We meet the
Welders tell us what’s best
In 1981 we turned the world of welding on its head by
introducing the first comercially-viable auto-darkening
welding filter. Ever since then the Speedglas brand
and the technology behind it has been the standard
to which others aspire.
Continually inspired by welders
For almost three decades now, we have worked closely with welders,
safety engineers and ergonomic specialists to constantly improve
the performance and comfort of our products. And we’ve persistently
collected user insights and comments from around the world to inspire
us to create this, our next generation of welding protection.
Our Voice of Customer studies revealed the following user priorities:
“Coverage is key.”
We made the new shield deeper and wider, providing greater coverage
of ears, neck and sides of the head.
“The shield must be comfortable to wear.”
We’ve totally changed the interface between the welder’s head and the
shield’s suspension system, eliminating pressure points, optimizing its
centre of gravity, and adding multiple adjustment options.
“The welding shield must be reliable.”
The 3M Speedglas 9100 Welding Shield and auto-darkening filters are
based on more than 25 years of expertise in developing and producing
extraordinarily reliable and durable equipment for highly-discriminating
professional welders.
Our sincere thanks to the professional welders that contributed their
thoughts and experiences to the development of the Speedglas 9100
shield - we hope you will enjoy the results!
“Fits just the way I want it to”
The comfort of the 3M Speedglas 9100 Welding
Shield is the result of extensive research and
development processes. We consulted with
international experts in ergonomics and anatomy to
ensure that we would produce the most comfortable
and protective welding shield ever.
“This changes how I experience welding”
Professional welders marvel at the stability and balance of the shield in
all positions - up, down or anywhere in between, the new pivot location
keeps leveraged forces to a minimum. With our new head suspension
we avoid pressure on vulnerable nerves, arteries and acupressure points;
areas that might cause pain or discomfort if they are put under pressure
for a period of time.
“So many more options!”
Welders are delighted to see all the welding filter options: A grinding
shade 3. Gas welding shade 5. Micro-plasma welding shade 8.
Arc welding shades 9 through 13. Sensitivity settings for normal welding
to low-amp inverter TIG welding, and even low-sensitivity setting
for when other welders are working nearby. More versatility, greater
optimisation… and more user satisfaction.
The new head suspension system provides for several adjustment combinations, so
the welder can “fit” the shield to his personal preferences and comfort settings.
Designed for ultimate protection
Safety is our ultimate goal; all features must
inevitably enhance the user’s protection. Even our
improved comfort designs are ultimately rooted
in safety: a shield can only work when the user wants
to continually wear it. By enhancing the shield’s
performance at all levels, we have made the most
appealing - and compelling - professional welding
shield within our range.
Great tools let you concentrate
Precision welding is demanding, but with the 3M Speedglas 9100
Welding Shield you can fully concentrate in safety and comfort. Protecting
your eyes and face from radiation, heat and sparks while providing an
accurate view of your work area, your Speedglas 9100 shield might soon
be considered your most important welding tool.
SideWindows: Exclusive, shade 5 filters that widen
your field of vision. SideWindows enable you to be more
aware of nearby moving machinery, tools and other
peripheral hazards.
The shield is available with or without SideWindows.
Welders can also use removable cover plates for when
peripheral vision is found to be distracting.
Increased coverage for ears and side of neck.
The shield is made from a lightweight, but durable
material that meets the mechanical strength
requirements of EN 175 level “B”.
An auto-darkening welding filter with superior optical
performance enables constant, comfortable vision.
Ultraviolet (UV) and infrared (IR) radiation protection at
all times, in all states.
Heat reflecting silver front.
Increased coverage for lower neck from heat
and welding sparks. Also available: flame-resistant
Tecaweld protector for extended neck and
ear coverage.
A head suspension that shapes to your head
The outside of the human head is lined with nerves,
arteries, and acupressure points. Applying pressure to
some of these points can make a person feel fatigued.
Working with Western and Chinese medical experts, we mapped
out the vulnerable areas of the head and avoided them with our new
head suspension design. Then, we created a design that better cradles
the head. As a result, you do not need to tighten the headband as much
as conventional ones to hold the shield firmly on your head.
Less pressure, more comfort
Less pressure on your head means improved comfort that lasts all day
long and the more comfortable you are in your protective gear, the more
you want to keep it in position, providing you with more continuous eye
and face protection from workplace hazards.
The front of the headband
self-adjusts to match
your forehead. Pressure
is evenly distributed to
sets of twin pads to fit the
exact shape of your head.
Two crown straps gently saddle the top of the head for
increased shield stability and better weight distribution.
Both straps are adjustable to fit virtually all head shapes
and sizes.
The back portion of the headband is self-adjusting and
swivels to fit different head shapes.
When wearing a cap backwards you simply turn the
back portion upside-down.
Four settings let you
determine the distance
between your face and
the shield. This allows
you to keep the shield as
close as possible to your
face for a greater view
and reduces the load on
your neck muscles.
Small, Medium or Large?
You can adjust the width
of the head suspension
to your own head size –
from 50cm to 64cm.
The headband can also be manually
tightened to your personal preference.
The smooth ratchet mechanism allows
for precise tightening control.
We’ve lowered the centre of gravity to be just
above your ears! This makes the shield more stable in
both the up and down positions, as well as reducing
the leveraged strain on your neck. Large, rubber,
overmoulded knobs make it easy to adjust the up-anddown pivot action, even when wearing gloves.
A snap adjustment allows you to set the shield at
9 different angles.
Reducing the possibility of neck strain
Feedback from professional welders led us to research
ways to further reduce the possibility of neck strain.
Our answer was: reduce the static and dynamic loads
on the neck. From a shield design standpoint, that
means keeping the shield as close as possible to the
head. By lowering the pivot point to just above your
ears, the shield stays as close as possible to the top of
your head when in the up position. In essence, we’ve
shortened the length of the “lever” to help reduce
forces on your neck muscles.
Improved shield angle adjustment and pivot action
For optimum vision and comfort the viewing angle through the welding
filter can be adjusted without losing the close-to-face fit of the shield.
You can now adjust the shield angle while wearing the shield. This helps
when handling work pieces at different heights.
The shield also has a smoother up-and-down pivot action that gently
“locks” in the up position - a light pull lowers the shield.
The lowered centre of gravity makes the shield feel more balanced and stable
in all positions - up, down, or anywhere in between. Because the shield is more
balanced, you do not need to tighten the headband as much, further increasing
your wearing comfort!
Keeps you cool and fog-free
Very often welders who keep their shield in the down
position for prolonged periods of time complain of
discomfort from stale air and reduced vision from
fogging inside the shield.
A unique ventilation solution: exhaust vents direct your
exhaled air out of the shield more effectively.
An innovative design
We have improved our design to direct exhaled air out of the shield more
efficiently with reduced fogging of the welding filter as an effect.
It can also reduce the build-up of heat, moisture, carbon dioxide (CO2)
and stale air within the shield. Welders report feeling more refreshed,
energetic and clear-headed all day long.
The inside protection plate now slides in from the
side to give a tighter fit that helps to lock out fogproducing moisture.
The exhaled air is channelled out via the
side exhaust vents.
The new inside cover plates quickly attach or detach
over the SideWindows (from the inside of the shield)
for either focused or full-viewing. There is also a shield
option available without SideWindows.
The design of the exhaust vents reduces the likelihood
of fogging of the welding filter.
The shield design is compatible with most 3M
Maintenance-Free Respirators that provide protection
against hazardous welding particles.
Better optics, bigger views
The 3M Speedglas 9100 Welding Filters continue
our tradition of outstanding optical quality, including
extremely uniform shading and minimal distortion
across the entire filter viewing area.
No compromises needed
More options mean more control for the welder
The shield option with SideWindows increases your vision even further,
enabling you to be more aware of peripheral hazards. All of these options
are about user comfort, personal preference, and optimum performance
for each specific application.
There are seven dark shade settings to choose from: shade 5 for gas
welding/cutting and shade 8 for micro-plasma and low amp TIG welding
as well as variable dark shades of 9 to 13. If needed, you now also have
the option to lock-in your shade, including the light state (shade 3)
for grinding. A comfort mode for tack welding helps to reduce eye fatigue
resulting from the eye constantly adjusting to differing light levels.
By selecting just the right setting for each task, the welder reduces eye
strain and improves the quality of every weld. Pick your viewing size:
the Speedglas 9100 series welding filter features three models –
normal, large and extra-large. The extra large Speedglas 9100XX filter
is 30% larger than any other Speedglas filter!
The Speedglas 9100 series includes three new
auto-darkening filter models that are differentiated
by size: the viewing area of the extra large Speedglas
9100XX filter is 73x107mm, making it 30% larger than
any other Speedglas welding filter!
The welding filter has new holders for the magnifying
lens making correct fitting easier.
The “tack welding comfort mode” uses
an intermediate light state (shade 5). If a
follow-up arc is not struck within two seconds,
the welding filter switches to the normal
light state (shade 3). This may help reduce
eye fatigue resulting from the eye constantly
needing to adjust to differing light levels
during tack welding.
Seven user selectable dark shades:
shade 5 for gas welding/cutting, shade 8 for
microplasma and low amp TIG welding and
shades 9 to 13 for most other types of
arc welding.
The delay function allows the user to set the
dark-to-light switching time.
Conforms to European Standard EN379 for eye
protection for welders.
Sensitivity of arc detection can be adjusted to provide
reliable switching for a wide range of arc welding
processes, amperages and situations. And you can now
“lock-in” any shade: the light shade for grinding or other
non-welding activities, or one of the dark shades to have
it function as a passive welding filter.
If versatility is what you want from a welding
shield, then the 3M Speedglas 9100 Welding Shield
is the one for you. It is designed to work in most
welding situations and applications.
