GENERAL
This
manual
has been
prepared especially
for
use
in
familiarizing
personnel
with the
design,
in
stallation, operation
and maintenance
ofthewelding
machine.
In
some
cases, the contents of this
pub
lication
are
generalized.
All information
presented
in this manual should be
given
careful consideration
to
assure
optimum performance
and service of the
equipment.
Process
information
is
available
by contacting
your
welding
distributor.
2-2.
RECEIVING-HANDLING
To
prepare the
welding
machine for
installation,
several
items should be
checked.
Clean all
packing
material from around the
unit and
carefully
inspect
for
damage
that may have been
caused
by
shipping.
Any
claims for loss
or
damage
that may have
oc
curred in transit must be filed
by
the
buyer
with the
carrier.
Copy
of bill of
lading
and
freight
bill will be
furnished
on
request
ifoccasiontofileclaimarises.
Be
sure
to
read all the instructions before at
tempting
to
operate
the
welding
machine.
When
requesting
information
concerning
the weld
ing
machine,
be sure,
to furnish serial and model
numbers.

DESCRIPTION
This
welding
machine is
designed
for
use
in
light
industrial
plants,
metal fabrication
shops,
auto
motive
repair shops
and for
general light welding
applications.
Two
welding
current
ranges
are
available.
The
high
range
provides ample
normal open circuit volt
age for average electrode sizes. The low range pro
vides maximum open circuit to
permit
the
use
of
smaller electrode
sizes.
The
180
amp
machine
uses
natural
updraft
cooling
and the 225 amp machine
uses
a
fan,
both
which
help
ensure
that the internal
components
are
kept
below the critical
operating temperatures,
pro
viding
the
duty cycle ratings
are
not
exceeded.
2-4.
SAFETY
Before
attempting
to make
primary
or
secondary
connections,
change
parts
or
make
repairs,
be
sure
the
welding
machine
is
completely
disconnected
from
the main power
line.
Before the
welding
machine
is
put
into
operation,
read the
complete
safety
section at the
front of this
manual.
This will
help
avoid any
possible injury
due
to misuse
or
improper
welding applications.

LOCATION
(Figure
3-1)
Proper component
operating
temperatures
on
the
225 amp model
are
maintained
by
the air stream
produced by
thefan
assembly.
On the 180 amp model
air
cooling
is
provided
by
means
of natural
updraft
through
the
vented
bottom.
Therefore
the
air
passages
in the front and bottom of the
welding
ma
chine must be
kept
open.
The
rear
of the
welding
machine should be
kept
a
minimum distance of 18
inches from the wall to
help
ensure
proper
cooling.
The
location
should
be
such
that
a
minimum
amount
of dust and dirt will be drawn
into the air
stream.
Preventive maintenance consists of
re
moving
the wrapper and
blowing
out the dust
ac
cumulation inside the
welding
machine,
For this
reason
it is desirable to locate the unit
so
that the
wrapper
can
be
removed
without
any
difficulty.
Four
mounting
holes
are
provided
in the
welding
machine base for machines that
require
mounting.
Figure
3-1
gives
overall dimensions and the base
mounting
hole
layout
for
console installation
or
other
installations
that
may
require
this
infor
mation.

PRIMARY CONNECTIONS
(Figure
3-2
&
3-3)
Most rural and
residental power
systems
are
of
the
115/230
volt,
single
phase type.
This
ac arc
welding
machine is
a
single
phase
unit
and
must be
connected
to
a
single
phase
power
line.
Consult
the local power and
light
company if
there
is
any
question
about
type
of
system
used
locally
or
the proper connection to obtain
single
phase
power
service to the
welding
machine.
All models
are
ordinarily supplied
with
an
attach
ed three conductor
cable.
Models
requiring
208
or
230 volt
primary
input
are
equipped
with
a
three
prong
polarized plug
and wall
receptacle.
The
wall
receptacle
should be installed in
a
con
venient
location
by
a
competent
electrician.
The
wall
receptacle
should be installed with the
grounding
