DESCRIPTION
The
RCDW-3A
is
a
remote
control
which
provides
a
separate
welding
condition
on
each
of
two
electrode
wires
using
a
dual
control/feeder
or
two
single
control/feeders
and
a
DELTAWELD
power
source.
This
unit
is
equipped
with
contactors
to
provide
cold
wire
(electrically
deenergized)
conditions
on
the
inactive
gun
when
both
guns
are
connected
for
the
same
polarity.
Interconnecting
terminals
on
the
remote
control
allow
different
polarity
connections.
It
is
designed
specifically
for
use
with
the
Gas
Metal-Arc
Welding
(GMAW)
and
Flux
Cored-Arc
Welding
(FCAW)
processes.
IMPORTANT
____________
This
unit
is
designed
to
be used
with
one
gun
active
at
a
time.

SAFETY
Before
the
equipment
is
put
into
operation,
the
safety
section
at
the
front
of
the
welding
powe~source
manual
should
be
read
completely.
This
will
help
avoid
possible

due
to
misuse
or
improper
welding
applications.
The

INSTALLATION
___________
Before
making
electrical
connections
necessary
for
the
proper
operation
of
the
remote
con
trol,
ensure
that
the
welding
power
source
and
con
trol/feeder
are
both
deenergized.
IMPORTANT
Duel
control/feeders
are
shipped
from
the
factory
wired
for
use
with
one
welding
power
source.
In
order
for
the
remote
control
to
function
pro
perly,
the
dual
control/feeder
must
be
modified
to
operate
as
if
two
we/ding
power
sources
are
in
use.
See
the
control/feeder
Owners
Manual
for
contactor
con
trol
modification
instructions.
Damage
to
equipment
will
result
if
the
dual
con-
trol/feeder
is
wired
for
use
with
one
we/ding
power
wurce
and
used
when
the
system
is
connected
with
one
gun

and
the
other

The
Remote

controls
provide
voltage
selection
within
the
welding

voltage
range
being
used.
When
the
Left
control/feeder
is
active,
the
remote
control
LEFT
VOLTAGE

control
will
be
active.
When
the
Right
control/feeder
is
active,
the
remote
control
RIGHT
VOLTAGE
INCREASE
control
will
be
active.
Rotating
the
VOLTAGE
INCREASE
controls
in
a
clockwise
direction
will
increase
the
load
voltage.
The
scale
surrounding
the
VOLTAGE
INCREASE
con
trols
is
calibrated
in
percentage
and
should
not
be
misconstrued
as
an
amperage
or
voltage
reading.
It
is
recommended
that
the
meters
be
read
whenever
it
is
necessary
to
know
the
amperage
and
voltage
output.
S
The
contacts
of
the
VOL

controls
are
of
the
continuous
type,
thereby
making
it
possible
to
adjust
these
controls
while

Prior
to
welding,
it
is
imperative
that
pro
per
protective
clothing
(welding
coat
and
gloves)
and
eye
protection
(glasses
and
welding
helmet)
be
put
on.
Failure
to
comply
may
result
in
serious
and/or
perma
nent
bodily
damage.
12.
Turn
on
the
shielding
gas
supply.

SHUTTING
DOWN
1.
Cease
welding.
2.
Allow
the
welding
power
source
to
idle
for
3
minutes
with
no
load
applied
to
permit
proper
cooling.
3.
Place
the
welding
power
source
POWER
switch
in
the
OFF
position.
Since
the
remote
control
derives
its
operating
power
from
the
welding
power
source,
the
remote
control
will
also
be
deenergized
when
the
welding
power
source
is
deenergized.
4.
If
the
control/feeder(s)
does
not
derive
its
operating
power
from
the
welding
power
source,
place
the
control/feeder(s)
POWER
switch
in
the
OFF
position.
~.
5.
Turn
off
the
shielding
gas.
CAUTION
___________
if
welding
is
performed
in
a
confined
area,
failure
to
turn
off
the
shielding
gas
supply
could
result
in
a
build
up
of
gas
fumes,
thereby
endangering
personnel
reentering
the
welding
area.
