DESCRIPTION
-
The
RC-IW
is
a
remote
con
trol
designed
to
control
an
INTELLIWELD
welding
power
source.
It
provides
the
capability
of
presetting
voltage
and
amperage.
The
RC-IW
is
equipped
with
a
CONTACTOR
switch,
ARC
CONTROL
potentiometer,
and
CC/CP
switch
for
controlling
functions
of
the
welding
power
source
when
it
is
in
the
remote
mode.
RD-lW-i
models
can
be
used
to
preset

(Figure
The

CONTROL
potentiometer
provides
variable
selection
of
short-circuit
current
to
suit
individual
welding
conditions
when
in
the
CC
mode
of
operation.
Rotating
this
control
clockwise
causes
the
current
to
in
crease
as
the
short-circuit
condition
is
approached.
When
this
control
is
set
at
some
value
above
0,
the
cur
rent
begins
to
increase
when
arc
voltage
drops
below
20
volts.
When
the
control
is
set
at
10,
the
short
circuit
current
is
considerably
higher
than
normal
welding
current.
This
provides
extra
current
for
arc
starting
in
out
of

as
well
as
for

manner:
1.
With

open-circuit
voltage
at
