in
a
compact
assembly.
It
contains
all
the
controls
and
equipment
needed
to
supply
welding
wire
to
the
welding
gun.

ROLL
ALIGNMENT
(Figure
2-3)
The
upper
drive
roll
mounting
bracket,
which
holds
the
upper
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
alignment.
If
the
drive
rolls
are
not
in
alignment,
proceed
as
follows
to
adjust
the
upper
drive
roll:
1.
Loosen
the
pressure
adjustment
knob.
2.
Using
a
9/16
wrench,
loosen
the
outer
securing
bolt.
3.
Using
a
5/8
wrench,
rotate
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.
4.
When
proper
alignment
is
achieved,
tighten
the
outer
securing
bolt
to
lock
the
drive
roll
in
position.
5.
Tighten
the
pressure
adjustment
knob
until
the
desired
amount
of
pressure
is
obtained.

ADVANCE/RETRACT
SWITCH
(Figure

The
ADVANCE/RETRACT
Switch
provides
a
means
of
mov
ing
the
electrode
wire
either
in
or
out
of
the
gun
without
having
to
touch
the
electrode
wire
to
the
workpiece.

ARC
CONTROL
(Figure

The
ARC
Control
provides
a
means
of
determining
the
rate at
which
welding
wire
will
be
fed
into
the
weld.
Rotating
the
ARC
CONTROL
in
a
clockwise
direction
(towards
the
10
setting)
will
decrease
the
rate
of
wire
feed
and
thereby
pro
vide
a
longer
arc.
Rotating
the
ARC
CONTROL
in
a
counter
clockwise
direction
(towards
the
0
setting)
will
increase
the
wire
feed
rate
and
thereby
provide
a
shorter
arc.

SWITCH
(Figure

This
control/feeder
is
equipped
with
a
RANGE
Switch
which
will
provide

ranges.
The

of
the

should
Only
be
used
when
the
setting
of
the
ARC
CONTROL
is

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
followed.
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.
