MANUAL
Mode
When
the
RCSP-45
is
in
manual
mode,
the
RCAP-1
Pendant
Control
functions
as
if
the
RCSP-45
did
not
exist
in
the
welding
system
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
source
capability.
The
scale
surrounding
the
control
is
calibrated
in
average
volts;
amperage
values
are
not
represented.
Rotate
the
control
clockwise
to
increase
weld
output.
When
the
RCSP-45
is
in
manual
mode,
the
RCAP-1
Pendant
Control
functions
as
if
the
RCSP-45
did
not
exist
in
the
welding
system
cir
cuitry.
Therefore,
when
the
WIRE
SIZE
SELECT
Switch
on
the
RCSP-45
is
in
the
MANUAL
posi
tion,
the
INDUCTANCE/ARC

Control
functions
as
an

as

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
SELECT
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
frequency;
it
does
not
affect
background
amperes,
peak
amperes,
pulse
width,
or
wire
feed
speed
values.

of
the

which
results
in
a

in
arc

When
this
control
is
set
at
0
(zero),
the
RCSP-45
maintains
an
arc
voltage
that
matches
the
welding
conditions
set
by

resulting
in
a

Rotating
the
control
counterclockwise
decreases

resulting
in
a

Adjusting
this
control
affects
arc

only;
it
does
not
affect

can
kill.
Do

Do
not
touch
the

is
present
at

IMPORTANT
____________
Although
the
term
CONTACTOR
is
used
on
the
nameplate
and
throughout
this
manual,
the
output
is
not
switched
on
and
off
by
a
physical

contactor.
The
output
is
controlled
by
relay
action
and
solid-state
components
on
circuit
boards.
Placing
the
CONTACTOR
Switch
in
the
ON
position
provides
open-circuit
voltage
at
the
weld
output
ter
minals
and
the
welding

whenever
the
welding

source
is
energized.
If
the
switch
is
placed
in
the
OFF

is
available
whenever
the
gun
trigger
is
depressed.
