which
holds
the

roll,
can
be
moved
on
a
horizontal
plane
in
order
to
facilitate
alignment
of
the
groove
in
the
pressure
roll
with
respect
to
the
groove
in
the
feed
roll.
The
pressure
roll
should
be
checked
for
proper
alignment
whenever
erratic
wire
feed
is
noted
or
whenever
the
pressure
and
feed
rolls
are
changed.
To
check
for
proper
alignment
of
the
pressure
roll,
remove
the
outlet
guide
and
look
into
the
outlet
guide
hole
in
the
drive

proceed
as
follows
to
adjust
the
pressure
roll:
1.
Loosen
the
pressure
adjustment
collar
and
pivot
it
off
of
the
pressure
roll
mounting

3.
Using
a
5/8
wrench,
rotate
the
adjustment

re
quired.
Rotating
the
adjustment
nut
clockwise
will
move
the

inward.
4.
When

is
achieved,
tighten
the

SHIELDING
GAS
CONNECTIONS
A
12~1/2
foot
hose
is
supplied
from
the
control
unit
for
making
connections
from
the
shielding
gas
source
to
the
control/feeder.
The
shielding
gas
which
is
fed
into
the
supplied
hose
will
be
supplied
to
the
shielding
gas
valve.
The
shielding
gas
hose
which
comes
from
the
gun
is
to
be
connected
to
the
GAS
hose
which
protrudes
from
the
motor
end
of
the
boom.

WELD
CABLE
CONNECTION
A
ten
foot,
2/0
weld
cable
extends
out
of
the
back
end
of
the
boom
for
making
secondary
connections
to
the
welding
power
source.
This
end
of
the
weld
cable
is
equipped
with
a
1/2
inch
lug.
The
opposite
end
of
this
weld
cable
is
connected
to
a
bolt
on
the
drive
assembly.
The
bolt
on
the
drive
assembly
serves
as
a
junction
point
for
joining
together
the
weld
cable
from
the
welding
power
source
and
the
weld
cable
from
the
gun.
2-10.
CONTACTOR
CONTROL
CONNECTIONS
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.

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.
2-11.
GUN
SWITCH
RECEPTACLES
A
four-prong
male
receptacle
protrudes
out
of
the
motor
end
of
the
boom
for
connecting
the
gun
plug
to
the
control/
feeder.
Ensure
that
the
securing
ring
on
the
gun
switch
plug
is
threaded
completely
onto
the
Gun
Switch
Receptacle.

CONNECTIONS
CAUTION
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

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

thereby
making
it
necessary
to
increase
the

that
the

can
lift,
loosen
the

and
rotate
the

so
that
the

threads
into
the

When
the
proper
adjustment
is
obtained,
tighten
the
jam

against
the
base
of
the
yoke.
If
a
lighter
gun
is
installed
on
the
control/feeder,
rotate
the

so
that
the
adjustment
rod
threads
out
of
the

or
the

present
on
the

from
1/4
to
3/4
