When
the
RCSP-45
is

the
RCAP-1
Pendant
Control
functions
as
if
the
RCSP-45
did
not
exist
in
the

cir
cuitry.
Therefore,
when
the
WIRE
SIZE
SELECT
Switch
on
the
RCSP-45
is
in
the
MANUAL
posi
tion,
the
VOLTS/ARC
POWER
Control
selects
the
weld
output
within
the
entire
range
of
the
welding
power
source.
In
the
CV
position,
the
control
adjusts
the
voltage
level,
and
in
the
CC
position,
the
control
adjusts
the
amperage
level
from
minimum
to
maximum
of
power

The
scale
surrounding
the
control
is
calibrated
in
average

are
not

Rotate
the
control
clockwise
to
increase
weld

When
the
RCSP-45

the
RCAP-1
Pendant
Control
functions
as
if
the
RCSP-45
did

Therefore,
when
the
WIRE

is
in
the
MANUAL

the
INDUCTANCE/ARC

PULSE
Mode
When
the
WIRE
SIZE
SELECT
Switch
on
the
RCSP-45
Control
is
in
a
PULSE
position,
the
IN
DUCTANCE/ARC
LENGTH
Control
allows
fine
tuning
of
the
pulse
frequency,
which
results
in
a
change
in
arc
length.
When
this
control
is
set
at
.0
(zero),
the
RCSP-45
maintains
a
pulse
frequen
cy
that
matches
the
welding
conditions
set
by
the
VOLTS/ARC
POWER
Control,
and
the
WIRE
SIZE
SELECT
and
WIRE
TYPE

switches.
However,
the
unit
has
a
built-in
feed
back
system
which
modifies
the
frequency,
thereby
stabilizing
the
arc
voltage.
Rotating
the
control
clockwise
increases
pulse
frequency,
resulting
in
a
longer
arc.
Rotating
the
control
counterclockwise
decreases
pulse
frequency,
resulting
in
a
shorter
arc.
Adjusting
this
control
affects
only
pulse

it
does
not
affect
background

or
wire
