Control/Feeder
Dimensions
Refer
to
Figure
2-1
for
dimensional
information
on
the
con
trol/feeder.
Lead
lengths
must
be
considered
when
installing
the
control/feeder.
If
the
welding
power
source
can
be
lo
cated
near
the
work
area,
the
control/feeder
can
usually
be
installed
on
top
of
the
welding
power
source.
Suitable
space
should
be
allowed
for
making
necessary
connections.

SHIELDING
GAS
CONNECTIONS
(Figure
3-1)
A
15
foot
hose
is
supplied
with
the
control/feeder
for
making
connections
between
the
shielding
gas
source
and
the
con
trol/feeder.
Attach
the
end
of
the
gas
hose
with
the
right-
hand
threaded
fitting
on
it
to
the
shielding
gas
source.
The
shielding
gas
hose
which
comes
from
the
gun
is
to
be
attached
to
the
shielding
gas
fitting
on
the
front
panel
of
the
control/feeder.
This
connector
has
right-hand
threading.

The
control/feeder
will
be
electrically
hot
internally
and
ready
to
operate
as
soon
as
the
115
volts
ac
plug
is
connected
to
the
115
volts
ac
source.
The
115
volts
ac
input
power
cable
can
be
distinguished
from
the
contactor
control
cable
(both
cables
being
10
feet
long)

by
the
three-prong
plug
attached
to
the
end
of
the
115
volts
ac
cable.
The
115
volts
ac
cable
must
be
connected
to
an
outlet
which
is
capable
of
supplying
115
volts
60
hertz
elec
trical
power.
2-4.
CONTACTOR
CONTROL
CONNECTIONS
(Figure
3.1)
The
contactor
control
cable
has
two
leads
extending
from
it.
These
two
leads
are
to
be
connected
to
the
contactor
control
facility
on
the
welding
power
source.
IMPORTANT
The
contactor
control
circuitry
that
is
to
be
used
in
conjunction
with
this
control/feeder
must
be
of
the
type
that
operates
on
115
volts
60
Hertz
power.
This
is
necessary
because
the
control/feeder
will
supply
115
volts
ac
through
the
contactor
control
cable
whenever
the
gun
switch
is
closed.

clean
at
all
times.
Also
ensure
that
the

of
the
control/
feeder.
The
amount
of
pressure
will
vary
from
one
given
set
of
welding
conditions
to
another
and
should
be
just

UPPER
DRIVE
ROLL
ALIGNMENT
(Figure
2-3)
The
upper
drive
roll
mounting
bracket,
which
holds
the
up
per
drive
roll,
can
be
moved
on
a
horizontal
plane
in
order
to
facilitate
alignment
of
the
groove
in
the
upper
drive
roll
with
respect
to
the
groove
in
the
lower
drive
roll.
The
upper
drive
roll
should
be
checked
for
proper
alignment
whenever
erratic
wire
feed
is
noted
or
whenever
the
drive
rolls
are
changed.
To
check
for
proper
alignment
of
the
upper
drive
roll,
remove
the
outlet
guide
and
look
into
the
outlet
guide
hole
in
the
drive
assembly.
Upon
viewing
the
groove
between
the
drive
rolls
it
should
be
noted
that
the
outer
edges
of
the
grooves
on
the
upper
and
lower
drive
rolls
should
be
precisely
aligned.
Figure
2-3
shows
examples
of
proper
and
improper
align
ment.
If
the
drive
rolls
are
not
in
alignment,
proceed
as
fol
lows
to
adjust
the
upper
drive
roll:
1
-
Loosen
the
pressure
adjustment
knob.

the
adjustment
nut
as
re
quired.
Rotating
the
adjustment
nut
clockwise
will
move
the
drive
roll
outward
and
counterclockwise
rotation
will
move
the
drive
roll
inward.

is
a

which
provides
a
means
of
determining
the
rate
at
which
welding
wire
will
be
fed
into
the

Rotating
the
WIRE

Control
in
a
clockwise
direction
will
increase
the

is
equipped
with
a
locking
arm
which
will,
when
rotated
fully
to

CIRCUIT
BREAKER
A
circuit
breaker,
located
on
the
rear
panel
of
the
control/
feeder,
provides
protection
to
the
control/feeder
circuitry.
In
the
event
the
motor
should
be
placed
in
an
overloaded
condi
tion,
the
breaker
would
trip
and
suspend
all
output.
Should
this
breaker
trip,
it
would
have
to
be
manually
depressed
to
reset.
trol/feeder,
is
a
momentary
contact
switch.
This
switch
will
energize
the
shielding
gas
solenoid
and
purge
the
shielding
gas
line
of
the
gun.
It
also
allows
the
shielding
gas
regulator
to
be
adjusted
without
energizing
the
welding
circuit.

INCH-ADVANCE
SWITCH

The
INCH-ADVANCE
Switch,
located
on
the

is
a
spring

switch.
When
actuated
it
completes
the
circuit

without
having
to

This
switch
will
permit

TROUBLESHOOTING
The
data
collected
here,
discusses
some
of
the
common
problems
which
may
occur
in
this
control/feeder.
The
assumption
of
this
data
is
that
a
proper
welding
condition
has
been
achieved
and
has
been
used
until
trouble
developed.
In
all
cases
of
equipment
malfunction,
the
manufacturers
recommendations
should
be
strictly
adhered
to
and
follo~d.
If
after
performing
the
following
procedures
the
trouble
is
still
not
remedied,
it
is
recommended
that
a
serviceman
be
called.
It
is
recommended
that
the
circuit
diagram
be
used
for
reference
during
troubleshooting.
