Intended Use
VarioProtect 3XL-W Digital TC | Version 1. 2 | EN 5
3 Intended Use
The Automatic Welding Helmet VarioProtect 3XL-W Di-
gital TC protects the eyes and face from sparks, splas-
hes and harmful radiation under normal welding conditi-
ons. The welding helmets may only be used for welding
and not for other purposes. They are suitable for almost
all welding processes, except oxyacetylene, laser and
gas welding processes. They do not protect against se-
vere impact, including fragments of grinding wheels, ex-
plosive devices, or corrosive liquids. Machine guards
and appropriate protection must be used. Avoid work po-
sitions where unprotected body areas are exposed to
flying sparks, direct and/or reflected radiation. Use
appropriate protection when exposure cannot be avoi-
ded.
If the auto-darkening filter is cracked, do not continue to
use the helmet: UV / IR protection may be compromised
and may cause burns to the eyes and skin.
Any use other than that described in these operating in-
structions is not permitted. Intended use also includes
compliance with all the information in these instructions.
Any use beyond the intended use or any other use is
considered misuse.
Unauthorized modifications or changes to the welding
helmet can invalidate the CE conformity and are
prohibited. Stürmer Maschinen GmbH accepts no
liability for design and technical modifications to the
welding helmet. The non-intended use of the welding
helmet as well as the disregard of the safety regulations
or the operating instructions exclude a liability of the
manufacturer for resulting damages to persons or
objects and cause an expiration of the warranty claim!
Technical Data
WARNING!
anger in case of misuse!

Fig. 6: Headband adjustment
Adjust headgear:
The helmet should be adjusted to effectively protect the
eyes and face during welding. The position of the head-
band and the rear headband can be adjusted manually
to ensure a secure fit. Turn the gear to adjust the tight-
ness until it feels comfortable. The front and back head-
band should be adjusted so that the forehead and back
of the head are firmly covered. See figure 6a.
Headgear depth:
The depth of the headgear can be adjusted to the posi-
tion where it sits over your forehead. Tighten the two
slotted straps to fit the top of your head. See figure 6b.
istance between viewing window and face:
The distance to the viewing window can be adjusted by
pressing the lateral pins and moving the sliders at the
same time. There are 5 distance positions available for
adjustment. See figure 6c.
Angle limitation position:
The ideal helmet position is reached when your eyes are
at a 9 ° angle behind the viewing window. There are 7
angle limit positions available for adjustment. Press the
side buttons and move the sliders at the same time so
that the helmet reaches the desired angle limit. See fi-
gure 6d.
After the adjustment mechanisms have been carried out,
the helmet should feel more comfortable for the welder to
wear than before. Work can be performed with high pre-
cision throughout.

Notes before commissioning
VarioProtect 3XL-W Digital TC | Version 1. 2 | EN 13
8 Notes before commissioning
- Before first commissioning, remove the protective
films on both sides of the protective screens (if
present).
- Before using the helmet for the first time, inspect all
parts for signs of use and damage. Scratched, torn
or holey parts should be replaced immediately be-
fore the helmet is used again to avoid serious in-
jury.
- Make sure the helmet is firmly in place before each
use.
- Select the shade level you require for the applica-
tion. Make sure the setting is correct by using the
colour chart.
- Adjust the head straps so that the welding helmet
sits as low on the head and close to the face as
possible. When using the welding helmet at a lo-
wer position, adjust the angle.
- Set the operating mode (welding or grinding). In
GRINDING mode, the filter remains bright.
- Set the protection level, delay time and sensitivity.
- Put on the helmet and check its tight fit and appro-
priate position.
- Before starting welding work, check the correct set-
tings with a function test.
- VAPORS AND GASES can be harmful to your
health. Keep your head away from fumes.
- Provide adequate ventilation, exhaust at the arc or
both to keep fumes and gases away from your
breathing zone and the general area.
- ARC arcs can injure eyes and cause skin burns.
- Always check the helmet and filter lens before wel-
ding to ensure they are fitted properly, in good
condition and undamaged.
- Check that the clear lens is clean and securely at-
tached to the helmet.
- Always wear safety glasses under the welding hel-
met and protective clothing to protect your skin
from radiation, burns and splashes.
- Make sure that optical radiation from the arcs of
other welders in the immediate vicinity does not
enter the helmet and the automatic dimming filter
from behind.
Welding produces sparks and drops of molten metal
that fly in all directions.
- The safety helmet must be worn to avoid serious
physical damage.
- Suitable additional safety clothing must be worn to
protect the rest of the body.
Correct use of the welding helmet
Before using the helmet, make sure that:
- The front cover and the filter are in the right posi-
tion and correctly fixed.
- All sensors and cells are not blocked.
- The protective films on both screens are removed.
- The red light is off, otherwise change the batteries.
- Keep the viewing area of the filter as close to your
eyes as possible during welding.
- If you weld for a long period of time, check the hel-
met occasionally and make sure there are no signs
of deformation or wear.
- Do not use the helmet without the transparent filter
protector (inside and outside): failure to do so may
result in a safety hazard or irreparably damage the
filter.
- People with particularly sensitive skin must be
especially careful: Materials that may come into
contact with the skin may cause allergic reactions.
- Check that the protection level corresponds to your
welding process. If the helmet has operating pro-
blems, refer to the chapter "Troubleshooting". If
the problem persists, stop using the helmet and
contact the person in charge or a dealer.
ATTENTION!
You may not use the welding helmet without the front
screens in front of and behind the filter cassette!
CAUTION!
Before each use of the welding helmet, check the
darkening function of the filter cassette (ADF) with
the help of a bright lamp.

Check the front cover to make sure it is clean and that
the sensors on the front of the filter cartridge are not
dirty. Also check the front/rear cover lens and the front
lens holder snap connection to make sure they are faste-
ned.
Check the helmet and viewing window for signs of wear
or damage before each use. Scratched, cracked or scar-
red parts should be replaced immediately before re-use
to avoid serious injury.
Adjust the headband so that the helmet sits as low as
possible on your head and close to your face. Adjust the
angle of the helmet in the lowered position by pressing
the side adjustment knob.
Do not make any modifications to the welding lens or
helmet other than those specified in this manual.
Failure to observe these warnings and / or to follow all
operating instructions may result in serious injury.
