Provided with high quality solar cells. No need to change batteries, includes a sensitivity and time
delay switch for switchover from dark to bright to prevent welding eyes if a high amperage is used
for weldings. The switcher can also be adjusted to fast-switching for tack and spot welding. The
model welding helmet is tested according to EN175: 1997 and enables complete neck protection
and protects the outside screen from scratchings when removing the helmet. The helmet is
provided with a comfortable frontlet and with a simple system for replacement. (not suitable for
the use of laser weldings, oxygen and acetylene weldings or cutting processes).

4. DETAILS FOR USE
Warning! (before usage the instructions have to be read completely and understood)
4.1 Before ClearVision Automatic welding helmet can be used the frontlet, switching time,
sensitivity and the required colouring have to be adjusted correctly.
4.2 SUITABLY ADJUST THE HELMET Adjust the frontlet so that the welding helmet is set as
deep as possible on the head and at close range to the face. When using the welding helmet at a
deep positioned spot adjust the angle by turning to the adjustable blocking ring (point Y of
instruction pict.1)
4.3 If the frontlet is set too high or too deep on the head the band which goes along over the
head has to be adapted. Therefore the clamping neps have to be pushed out at the end of the
band out of the holes. Then both parts of the band must be adjusted to the required size and the
clamping neps have to be pushed into the next holes (see adaption 'W' in pict.1).
4.4 Test the fit of the frontlet by tilting the helmet upwards and downwards several times. If the
frontlet slips adapt it once again until it fits tightly.
4.5 ADJUST THE DISTANCE BETWEEN HELMENT & FACE The helmet has to be flapped down
(tightly) to adjust the distance between helmet and face. Switch off the knobs at both sides and
push the helmet closer or push it away from the face (see adaption 'Z' in pict.1). It is important
that both eyes have the same distance to the view because otherwise the darkening effect gets
unbalanced. Then switch on the knobs. The adjustment progress is done.
4.6 ANGLE ADJUSTMENT OF THE HELMET IN FLAPPED DOWN POSITON
If the helmet is flapped down (tightly) and the view is not in line with the eyes, furthermore the
helmet can be adapted by selecting one of three possible positions of the hinge plate (see pict.2).
Behind the knob you can find a small screw which leads through the helmet into one of tree
holes of the hinge plate (see A, B, C in pict.2) Loosen both screws anticlockwise so that they
come out of the hinge plates but still stick in the helmet.
