GENERAL
The
purpose
of
this manual is
toprovidethe
basic
information
required
to,
and maintain
the
control/feeder.
This
manual will
restrict
It
self
mainly
to the
wire
control/feeder
and its
optional
equipment.
For
specific
information
on
its
gun
or
torch,
refer
to
the
respective
manual.
1.2.
DESCRIPTION
The
control/feeder
is
of
the
constant
wire
feed
speed
type
and is
designed
to be
used
in
con~
junction
with
a
CP
(Constant
Potential)
type
of
weld
ing power
source.
This
unit
was
designed
to
handle
.030
to
3/32
mild
and
low
alloy
solidwiresand.045to 1/8
flux
cored
wires.
Either the short
circuiting
method
of
transfer
or
the
spray
type
arc
may
be
utilized.
The
control/feeder
comes
from
the
factory
equipped
with
a
30
tooth
fiber
gear
on
the
motor
and
a
24
tooth
steel
gear
on
the
drive.
This
combination
will
provide
up
to
550
ipm.
A
24
tooth
fiber
and 15
tooth steel
gear
may
be ordered
as
optional equip
ment to
provide
the
flexibility
of
the
seven
different
wire
feed
speed
ranges.
This
control/feeder
is
a
heavy duty
wire
feeding
unit
combining
both the
wire
feeder and
the
control
in
a
compact
assembly.
It
contains
all
the controls
and
equipment
needed
to
supply weldingwire,
shield
ing
gas
and coolant
(optional)
tO the
welding
gun
or
torch.
This
unit
consists
basically
of
a
control
assembly,
a
drive
motor
with reductional
gear
box
assembly,
drive
roll
assembly,
wire
guides
and
a
spindle
and hub
assembly
to
accommodate
a
reel
assembly
for
handling
wire
coils
or
spool
assembly
for
handling
wire
spools.
The
control
assembly
contains
a
solid
state
type
speed
control
for
providing
precise
regulation
of
motor
speeds
over
a
wire feed
range
of
15
to
850
ipm.
To
prevent
override
or
run
out
of
the
wire at
the
torch
or
gun
tip,
the wire
feed
speed
control
provides
dynamic
breaking
of
the
motor
when the
switch
on
the
gun
or
torch
is
released.

assembly.
The
control
unit
requires
115
volt
60
hertz
ac
from
the
welding
machine
or
external
source
for
operation.
This
115

Is
connected
to
the control
assembly
and
is

as
long
as
It
can
be
actuated
by
applying
115

incorporated
in
the
control
assembly
provides
a
low
voltage
(24
volts)
across
the
