• SENSITIVITY
The sensitivity can be set to "HI" (high) or "LO" (low) by
using the infinitely dial knob on the back of the shade
cartridge. The "Mid-High" setting is the normal setting for
everyday use. The maximum sensitivity level is appropriate
for low welding current work, TIG, or special applications.
Where the operation of the helmet is disturbed by excess
ambient light, or another welding machine close by, use the
"LO" setting. (See fig. 3a). As a simple rule for optimum
performance, it is recommended to set sensitivity to the
maximum at the beginning and then gradually reduce it,
until the filter reacts only to the welding light flash and
without annoying spurious triggering due to ambient light
conditions (direct sun, intensive artificial light, neighbouring
welder's arcs etc.).
• SELECTING DELAY TIME
When welding ceases, the viewing window automatically
changes from dark back to light but with a pre-set delay to
compensate for any bright afterglow on the workpiece. The
delay time / response can be set to "S" (short: 0.1 sec.) or
"L" (long: 1.0 sec.). As you require using the infinitely dial
knob on the back of the shade cartridge. (See fig. 3b). It is
recommended to use a shorter delay with spot welding
applications and a longer delay with applications using
higher currents. Longer delays can also be used for lower
current TIG welding, and TIG / MIG / MAG pulse.
• 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 (See fig. 4).
Under this situation, the indicator would turn green and flash
every 3 seconds (See fig. 2). Before restarting welding
work, ensure that the shade function is turned back on
before welding again.
• ADJUSTING THE FIT OF THE HELMET
The overall circumference of the headgear can be made
larger or smaller by rotating the knob on the back of the
headgear (See adjustment "Y" in fig. 5). 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.
• If the headgear 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
pin 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 pin through the nearest hole (See adjustment "W"
in fig. 5).
• Test the fit of the headgear by lifting up and closing down the helmet a few times while
wearing it. If the headgear moves while tilting, re-adjust it until it is stable.
