for
making
connections
from
the
shielding
gas
source
to
the
Shielding
Gas
input
fitting
at
the
rear

These
fittings
have
a
right-hand
thread.
The

the
Shielding
Gas
output
fitting
at

E.
CAUTION
Ensure
that
durtng
all
adiustmant
procedures,
full
threads
on
the
adiustment
rod
are
maintained
through
the
yoke.
If
full
threads
are
not
maintained,
the
boom
may
suddenly
drop
down
and
cause
injury
to
person
nel
or
damage
to
equipment.
The
amount
of
weight
which
the
boom
can
retract
into
the
upright
position
when
released
can
be
varied
by
adjusting
the
jam
nut
and
adjustment
rod
located
at
the
base
of
the
boom.
If
a
heavier
gun
is
installed
on
the
end
of
the
boom
thereby
making
it
necessary
to
increase
she
amount
of
weight
that
the
boom
can
lift,
loosen
the
jam
nut
and
rotate
the
adjustment
rod
so
that
the
adjustment
rod
threads
into
the
yoke.
When
the
proper
adjustment
is
obtained,
tighten
the
jam
nut
against
the
base
of
the
yoke.
If
a
lighter
gun
is
used
with
the
Swingarc,
rotate
the
adjustment
rod
so
that
the
adjustment
rod
threads
out
of
the

held
in
any
desired
position.
Rotating
the
Locking
Knob
in
a
counterclockwise
direction
will
permit
the

travel.
Changing
the
position
of
the
Locking
Knob
to
the
other
threaded
holes
provided
along
the
side
of
the

Slide
the
spool
of
wire
onto
the
hub
(4)
so
that
the
wire
will
feed
off
the
top
of the
spool.
The
spool
turns
in
a

direction.
Rotate
the
spool
until
the
hole
in
the
spool
aligns
with
the
pin
in
the

Slide
the
spool
Onto
the

until
it
seats
against
the

ADJUSTMENT
OF
HUB
TENSION
(Figure
2-2)
Check
the
hub
tension
by
slowly
pulling
the
wire
toward
the
feed
roll.
The
wire
should
unwind
freely,
but
the
hub
tension
should
be
sufficient
to
keep
the
wire
taut
and
prevent
backlash
when
the
wire
feeding
ceases.
If
adjustment
is
required,
loosen
or
tighten
the
hex
nut
(10)
on
the
end
of
the
spindle
support
shaft
(1)
accordingly.

WELDING
WIRE
THREADING
CAUTION
U
Prior
to
threading
the
welding
wire
through
the
gun,
ensure
that
weld
power
is
not
available
at
the
weld
head.
1.
Install
the
wire
(reel-type
or
spool-type)
as
instructed
in
Section
2-16
or
2-17.
2.
Cut
off
any
portion
of
the
free
end
of
the
wire
which
is
not
straight.
Ensure
that
the
cut
end
is
free
from
rough
surfaces
to
permit
proper
feeding.
3.
Route
the
wire
through
the
wire
guide
tube
on
the
side
of
the
boom,
over
the

5.
Feed
the
wire
through
the
inlet

guide,
past
the
drive
rolls,
and
on
into
the outlet
wire
guide.
Feed
approximately
4

of
wire
into
the
outlet
wire
guide.
.
If
when
the

are
not
aligned
properly
(see
Section
2-6),
pivot
the

one
tooth.
6.
Pivot
the
gear
cover
closed
making
sure
the
teeth
on
the
pressure
gear
mesh
with
the
teeth
on
the
drive
gear.
The
welding
wire
must
also
be
in
the
grooves
of
the
drive
rolls.
7.
Pivot
the
pressure
adjustment
wing
nut
until
the

are
tight
against
the
welding
wire.
Do
not

to
the
unit
and
thereby
place
it

Placing
the

will
shut
the

I_______
Placing
the
POWER
switch
in
the

position
does
not
remove
power
from

Completely
terminate
all

(see
Instruction

provides
a

Rotating
the
WIRE

control
in

will
increase
the

of
the

When
the

wire
will
feed
at
the

when
set

is
calibrated
in

is
a

This switch
will
energize
the

and
purge
the

of
the

also
allows
the

In
the

BURNBACK
CONTROL
(Optional)
The
burnback
circuitry
in
this
control
provides
a
means
of
keeping
the
welding
wire
from
sticking
to
the
workpiece
after
the
gun
switch
is
released.
The
burnback
capability
in
this
control/feeder
will,
depending
upon
the
setting
of
the
BURNBACK
control,
keep
weld
current
present
on
the
welding
wire
from
0
to
15
cycles
after
the
wire
has
stopped
feeding.
This
delay
action
will
permit
the
welding
wire
to
burn
back
to
a
point
where
it
will
neither
stick
to
the
workpiece
nor
the
contact
tube.
If
the
welding
wire
sticks
to
the
contact
tube,
rotate
the
BURNBACK
control
to
a
more
counterclockwise
position.
If
the

INSPECTION
AND
UPKEEP
Usage

type
of
maintenance.
Inspect
equipment
as
follows:
1.
Make
sure

source
is
shut
down.
2.
Inspect
gun

broken
areas,
cracks
and
loose

replace
as
required.
3.
Carefully
remove
any

which
may
accumulate
around

Use
a

can
be
performed
with
a

To
clean
the

it
will
be
necessary
to
first
remove
the
drive
roll(s)
(see
Section
