Let us introduce Aketek
Åke Hörnell is the inventor of Auto-Darkening Welding
Filters, an innovation that has improved the working
conditions for welders around the globe. Åke patented the
technology and founded a company that began to
introduce products under the trade name Speedglas. After
a long and successful expansion ending up as a market
leader, the company was acquired by 3M Group. After
some years of non-compete restrictions, Åke Hörnell
could not resist the temptation and challenge to reenter
the welding safety business. A new star –Aketek –was
born.
Aketek welding helmets are Swedish designed and built
based on more than 30 years of expertise. They make
welding safer, more comfortable and easier. With low
cost, high performance and easy operation, we believe
that Aketek welding helmets make every welder a better
welder.
Aketek –best possible optics
Aketek welding helmets have the best classes for optics performance (1/1/1/1) according to
the European standard EN 379. They work for all type of electric arc welding. The
switching time from light to dark is around 0,0001 sec. The electronic is extremely low
power and the in-built battery, supported by a solar cell, has a long life time. At all Aketek
welding helmets switching to grinding mode is possible.
Operating instructions are also available at www.aketek.se/english-information.

1.0 Information
Welding without proper eye protection is dangerous. Automatically darkening welding
filters provide reliable protection against UV/IR radiation, heat, sparks and weld spatter in
both light and dark states. The automatic dark state protects the eyes from the strong light
from the welding arc. The automatically darkening welding filter must always be used
with the welding helmet.
Welding helmets equipped with automatic welding filters are easy to use. When the
welding arc is struck, the glass darkens automatically and when the welding stops, the
glass returns to its light state again. This provides the following advantages: both hands
free, safer working environment thanks to protection against UV/IR radiation for eyes and
skin, no glare from the welding arc, better quality and faster and more efficient welding.
These operating instructions must not be removed from the product, except by the user of
the welding helmet. The operating instructions must always be available to a new user. If
you don’t have the operating instructions, they can be downloaded at www.aketek.se.
2.0 Areas of applications
The welding helmet together with the automatically darkening welding filter and
protection plates should only be used for electric arc welding and plasma welding. This
includes welding with coated electrodes, MIG/MAG welding, TIG welding and plasma
welding/cutting in the temperature range -5 °C to +55 °C. Do not use the welding helmet
for uses other than those specified on the next page.

3.0 Preparations before use:
3.1 Make sure that the welding helmet is suitable for the welding to be performed.
Check that the welding filter cassette and both inner and outer protection plates are clean
and not cracked or scratched. Make sure that the protective film is removed from the inner
and outer protection plates before using the welding helmet.
3.2 Do not use sharp tools or objects that could damage the welding helmet and may
cause the product warranty to be invalidated.
3.3 The welding helmet should be placed on the head so that the black sweatband of the
headband comes towards the forehead and the orange neck pad and the size adjustment
end up in the neck. Adjust the size so that the helmet fits firmly and comfortably. The
headband has double adjustable head straps and flexible neck plate for increased comfort.
The headband is adjustable forwards and backwards in five steps to get the best distance
to the welding glass. The headband has an adjustable angle up and down to get the best
view through the welding glass. The headband can easily be detached from the welding
helmet, for example for changing sweatbands. See picture of the headband on the page 9.
3.4 After correct adjustment, the welding helmet should cover the entire face and head.

4.0 In use
There are two knobs with adjustment options on the inside of the welding filter cassette.
The knob on the left affects the sensitivity of the light detectors. Counterclockwise rotation
reduces the sensitivity and clockwise rotation increases the sensitivity. The detectors do
not respond to sunlight and constant ambient light, but only to rapidly varying lights such
as the welding arc. Therefore, it is recommended to normally use maximum sensitivity.
The knob on the right is for setting the shade number, with the lowest shade 8 (lightest
setting) at counterclockwise rotation to stop, and with the highest shade of 12 (darkest
setting) at clockwise rotation to stop. When welding, select position welding on the
welding filter cassette, and when grinding select grind.
Automatically darkening welding filter must be used with outer and inner protection
plates. The protection plates protect against heat, dirt, welding splashes and welding
spatter. The outer and inner protection plates must be replaced if they become scratched or
damaged in any way that impairs the view. The protection plates from Aketek are made of
polycarbonate plastic (PC) with a scratch-resistant surface coating. If protection plates are
not used, the welding filter cassette will be damaged by weld spatter and the warranty
will be invalidated.
5.0 Maintenance and cleaning
Inspect the welding helmet regularly, both before and after use. Do not use the equipment
until any damaged or defective parts have been replaced, as this can affect the work
negatively. The welding filter cassette is sensitive to water.
5.1 The welding helmet must be handled with care. Do not leave it in a dirty
environment.
5.2 The welding helmet has an outer protection plate of polycarbonate plastic (PC) with
a scratch-resistant coating that protects against mechanical particles and welding spatter.
Over time, however, the transparency will deteriorate and the protection plate will then
need to be replaced, see info under 7.0. If cleaning is required, clean with a damp cloth and
wipe with a clean cloth.

5.3 In normal use, the welding glass cassette does not require any special maintenance
for the entire lifespan.
5.4 Other parts of the welding helmet can be cleaned with a cleaning cloth moistened in
water with a little detergent and dried with a clean cloth.
5.5 See recommended maintenance list below. You can also download the
recommended maintenance list from www.aketek.se.
6.0 Storage and transport
Make sure that the welding helmet with components is not damaged. The welding helmet
must not be transported in contact with other objects or stored near sharp objects. The
storage area must be dry, not near heat sources or in direct sunlight. Store the welding
helmet at a temperature between -10 °C and +40 °C. This welding helmet does not contain
any special or hazardous materials. It can be discarded in the same way as ordinary
electrical equipment.

7.0 Installation and replacement of parts
If the Aketek automatic welding filter cassette, a protection plate or grinding visor needs
to be replaced, follow the instructions below. Note that the welding filter cassette protects
against UV/IR radiation and is in the light state before welding and in the dark state
during welding. The transparent protection plates protect the automatic welding glass
against mechanical impact and weld spatter during the welding work. The protection
plates are also necessary for the welding helmet to meet the safety requirements
demanded by standards.
7.1 Remove the frame that holds the outer protection plate
7.1.1 Press the four locking hooks located on the inside of the welding helmet, look at
picture 1. The frame should come loose from the hooks on the front.
7.1.2 Lift off the frame together with the protection plate, look at picture 2.

10.0 Please note the following
10.1 This welding helmet should only be used for electric arc welding, plasma welding
and related grinding.
10.2 The welding helmet must always be equipped with an automatically darkening
welding filter as well as outer and inner protective plates.
10.3 If the automatic welding glass does not darken at the start of welding, stop the work
immediately. Check that nothing obscures the light detectors or that the working distance
is too large. Check the sensitivity setting. Some welding processes require that the light
sensitivity is set to maximum sensitivity. It the welding glass flashes the temperature may
