may
be obtained
as
optional
equipment.
To install the

2-9. PREPARATION
OF
CONTROL/FEEDER
On
new
equipment,
or
as
a
result
of
wire
size
changes,
it
is
necessary
to
install
the
required
speed
change
gears,
drive
roll
gears,
and
wire
guides
to
accommodate
the
particular
wire
size
and thread
the
welding
wire.
Having
selected
the
desired
wire
size
and related
parts,
proceed
to the
following
installation and
adjustment.

The
selection
of
the
proper
gear
combination
is
important
In
obtaining
the
ultimate
in
performance
of
the
control/feeder.
With
the
proper
gear
com
bination
a
finer
wire
feed
speed
adjustment
can
be
made
and the
drive
motor will
deliver
maximum
power.
The
feeder
may
be
usedatany
setting
on
the
control/feeder
where
an
adequate
feeding
condition
can
be
obtained.
It is recommended that the drive
motor
not be
operated
consistently
at
a
wire
feed
speed
less
than
a
30
percent
setting
on
the
control/
feeder.
Operation
with
asettingof
less
than
30
per
cent when
using
large
diameter
electrode
wire,
may
result
in
a
high
current
draw
by
the motor
causing
the circuit
breaker
to
activate.
Also,
operation
on
the
lower 30
percent
of
the
control
may
not
provide
an
acceptable
wire
feed
speed
adjustment.
Selecting
gear
combinations,
so
the
feeder
will
function
as
high
as
possible
on
the
control/feeder
setting,
will
give
the
best
operating
conditions.

necessary,
re

2.
Loosen the
two
bolts
fastening
the

to the base
of
the
control/feeder.
3.
Slide
the

forward.
4.
Remove
the

from
the
Drive

from
the drive

Refering
to

The control/feeder
uses
a
fiber
and
a
steel
gear
in
the
drive train
between
the
drive
motor and the
wire
drive
rolls.
Proper
clearance
between
the
fiber
and steel
gear
is
important.
The
proper
clearance
is
.007
inch.
This
is
approximatelythe
same
thick
ness
of
two
sheets
of
standard
writing
paper.
The
easiest
method
to
obtain
the
proper
alignment
is to
be
sure
the
motor
is
fastened
securely
to
the
base
plate.
Then
insert
a
piece
of
.007
thick
paper
(or
two
thicknesses
of
standard
writing
paper)
between
the
fiber
and
steel
gear,
check the
alignment
of
the
gears
(the
two
gears
must be
running
in
a
straight
line)
and
then
tighten
down the
drive
roll
assembly.
If
this
proper
clearance
is
not
maintained
in
the
gears,
they
may
wear
severely,
bind
and
cause
erratic
wire
feed,
or
even
break.
