1. Before Use
1-1 Servo Glas
The auto darkening welding filter in the SV4000 has been designed for arc welding and gas
cutting. It is suitable for all normal arc welding processes such as MIG, MAG, TIG, SMAW,
Plasma Arc and Air Carbon welding.
Before use the shade control should be adjusted to the appropriate level based upon EN169
(European Standard specifications or equivalent) or other appropriate safety guidelines. When in
doubt please consult your safety representative or your authorized Servo Glas 4000 distributor.
The Servo Glas 4000 provides continuous protection from ultraviolet and infrared radiation to
the maximum level indicated on the product and as described in the relevant Standards. This
protection is fail-safe and is not compromised by loss of battery power or other electronic failure.
The Servo Glas 4000 welding filter cartridge is fitted with two independently operated sensors
that detect the welding arc and respond accordingly resulting in the appropriate darkened filter
state as set by the user and as indicated on the scaled adjustment. Please note that professional
judgement may be required to achieve the best results. When in doubt consult an authorized
safety representative or your Servo Glas distributor and always maintain a conservative
attitude towards operation.
Two replaceable lithium batteries type CR2032 (3V) are used as major power sources. An
additional solar cell panel extends battery life and ensures efficient operation. When operating
normally the welding helmet will switch on automatically and switch off automatically to save
power a few minutes after the last welding arc has been detected.
To provide a general check of system status you may wish to set the shade control to 11 and
hold the helmet towards a bright incandescent light source. Under normal circumstances the
filter will change from light to dark state and back to light state again as you move the helmet
away. Please note that if you have any questions or there is any doubt about the performance of
your Servore product you should refer to your authorized safety representative or Servo Glas
■ Genuine Servo Glas front and inside cover plates must always be
used with Servo Glas 4000 welding filter and helmet. Failure to do so
may result in injury and also void any warranty.
■ Servo Glas 4000 is not designed for use in overhead welding
applications where additional protection may be required.
■ Check for normal operation of the auto-darkening welding filter.
If the welding filter does not darken in use stop welding immediately.
■ Always select the appropriate shade before use according to the
type of welding and current/amperes required. When in doubt refer to
your authorized safety representative.
2. Markings
The appropriate available shade number markings and range are indicated on the product.
Please ensure that the appropriate shade number is selected before welding. Used properly
the ServoGlas 4000 provides eye and face protection to meet or exceed EN379 and

5-1. Shade Control
5-2. Light Sensitivity Control
Where problems are experienced during welding at low currents
[e.g. TIG] or there is a high level of ambient light please follow
these steps: First try adjusting the sensitivity control switch. If
this does not solve the problem hold the helmet close to the
target object and adjust the shade control completely clockwise.
If the welding filter continues in the bright state, leave the control
set at this point. If the filter changes to the dark state, turn the
shade adjustment knob until the filter just switches into the light
state. The filter will then be adjusted correctly. If the welding
filter still does not respond appropriately please try adjusting the
sensitivity control again (having previously adjusted the shade
control as explained above)
The required filter dark state can be selected by
using the shade control. The ServoGlas 4000
can be adjusted between shades 9 to 13 with
the embossed arrow on the dial indicating the
current adjustment.
Always use the appropriate shade for the
welding operation you are undertaking. When
in doubt please consult the relevant Standards
or your authorized safety representative.
Recommended shade numbers according to BS 679, DIN 4647-1 and EN169
5-3. Delay Control
Adjustment of the speed at which the welding filter clears
can be reduced by means of the delay control toggle switch.
When this switch is set to 'Fast' the screen will clear more
According to the conditions of use, the next greater or the next smaller scale number can be used.
6. Maintenance
Always ensure that all maintenance procedures are conducted in a clean
dry place.
Use clean dry hands and avoid direct contact with any glass surfaces.
Handle cover plates and welding filter by the edges and carefully clean off
any dirt or debris before re-use.
6-2. Replacement of Inside Cover Plate
To replace the protective inside cover plate the filter cartridge must be removed from the
retaining guide frame. Always ensure this process is conducted in a clean dry place and
take care not to drop the filter cartridge. To remove the filter cartridge from the retaining
frame gently expand the frame, you can then separate and remove the cartridge from the
You will now be able to slide out the inside cover plate as shown in the diagrams.
6-1. Replacement of Front Cover Plate
To replace the front cover plate, the filter cartridge must be removed from the recess in
the helmet. Unlock the either side of cartridge holders pushing upward.
After removing the filter cartridge from the recess in the helmet, gently push out the old
plate. Ensure that the protective plastic film is removed from both sides of the new cover
plate and that it is clean and free of any scratches. Carefully slot the new plate into the
recess in the helmet.
