4. INSTRUCTIONS FOR USE
WARNING! Before using the helmet for welding ensure you
have read and understood the safety instructions in Section 1.
4.1
The helmet comes ready assembled but before it can be
used it must be adjusted to fit the user properly.
4.2
ADJUSTING THE FIT OF THE HELMET.
The overall circumference of the headband can be made
larger or smaller by pushing in and rotating the knob on the
back of the headband (See adjustment ‘A’ in fig.1). This
can be done whilst wearing the helmet and allows just the
right tension to be set to keep the helmet firmly on the
head without it being too tight.
4.3
If the headband is riding too high or too low on your head
adjust the strap which passes over the top of your head. To
do this release the end of the band by pushing the locking
pip out of the hole in the band. Slide the two portions of the
band to a greater or lesser width as required and push the
locking pip through the nearest hole (See adjustment ‘B’ in
fig.1).
4.4
Test the fit of the headband by lifting up and closing down
the helmet a few times whilst wearing it. If the headband
moves whilst tilting re-adjust it until it is stable.
4.5
ADJUSTING DISTANCE BETWEEN HELMET & FACE
.
To adjust the distance between the helmet and your face in
the down position loosen the tilt knobs (D) on either side of
the helmet and slide it nearer to or further from your face.
(See adjustment ‘C’ in fig.1) It is important that your eyes
are each the same distance from the lens otherwise the
darkening effect may appear uneven. Re-tighten the tilt
knobs when adjustment is complete.
4.6 SELECTING DELAY TIME/RESPONSE TIME
The delay time in which it takes the lens to change from
dark to light or vice versa can be varied from 0.1sec to 1
sec, this adjustment is carried out by turning the delay time
knob on the inside of the lens (see fig.3).
4.7 SENSITIVITY
4.7.1 For normal ambient light conditons set the sensitivity knob
to the high setting (fig.3).
4.7.2 For conditions where there is an excess of light, which may
affect the performance of the lens, turn the knob to the low
setting.
4.8 SELECTING SHADE LEVEL
Refer to the shade guide in Section 7 and adjust the knob
on the side of the helmet to the correct setting (fig.2).
4.9 SELECTING THE GRIND OPTION
When the shade knob is turned to the “grind” position the
shade function is turned off allowing a clear view to grind a
weld with the helmet providing face protection. Ensure that
the shade function is turned back on before welding again.
