The
sensitivity
can
be
set
at
“
HI”
(
High
)
or
“
LO”
(
Low
)
by
using
the
infinitely
dial
knob
. (
See
Fig

)
As a simple rule for optimum performance, it is recommended to set sensitivity
at the High at the beginning and then gradually reduce it, until the filter reacts only
to the welding light flashes and without annoying spurious triggering due to ambient
light conditions (direct sun, intensive artificial light, neighboring welder’s
arcs etc.).
“
HI
”
(
High
)-
Most for welding applications but specially
for
low welding current
work.
“
L O ”
(
L ow
) -
Only in some specific surrounding lighting conditions in order
to avoid unwanted triggering.
