tly
the circuitry contained on
the printed circuit board
W16-20.
The desired wirefeed mator.
speed
is
determined
by
the setting
of
the
wire speed potentiometer.
The proces5ed potentiometer wiper

This

is
applied
tu
the pin

input of the cumparator
IC2/1,
where
it
is
compared to the potentiometer wiper uol tage.
The
difference between these two uul tayec is amp1 ified
by
IC2/1
and
the resultant uoltage applied to the pin
6
input
sf
IC2/2,
where
it
is. compared
to
a
mains synchronized
rarr~p
waueform. The result of
this comparison determines the conduction angle of the
SCR’s
l

2,
and hence the motor speed.
The
ouer-all
effect
is
such that,
if
the

falls
below the desired setting, the circuitry

If

occurs.
When the
