Do not use weldm_ electrode as-aclaarette hg_ter, . -
e. Connect the welder only to a source of electncal'.-
power meeting the requirements, irrcluding
grounding, of the National Electrical Code (ANSI Cl)
and local codes.
f. Electrode coating may be electrically conductive-
use welding gloves when changing electrodes.
2. EYE AND BODY PROTECTION
a. Use helmet, filter, and cover plate complying with
ANSI Z87 1 to protect your eyes and face from
sparks and the rays of the arc when welding or
observing open arc welding,
b Always wear safety goggles with side shields
complying with ANSI Z871 when in a welding area,
or when near slag chipping operation
c. Wear oil free protective garments, such as leather
gloves, heavy shirt, cuffless trousers and high shoes.
d Protect other near-by personnel with suitable
non-flammable screening_
e
Welding can produce fumes and gases which are
dangerous to health, Keep your head out of the
fumes, Use enough ventilation, exhaust at the arc, or
both, to keep fumes and gases from your breathing
zone and the general area, Take even greater care
when welding on galvanized or cadmium plated steel
and other metals which produce toxic fumes
Ab-supplied helmets may be necessary
f When working above floor level, protect yourself
from a fall should you get a shock Never wrap the
electrode cable around arty part of your body
g Do not weld in locations close to chlorinated
2
hydrocarbon vapors coming from degreasing,
cleaning, or spraying operations The heat of the rays
of the arc can react with solvent vapors to form
phosgene, a highly toxic gas, and other irritating
products
h Unprotected spectators must be kept clear of the
welding area due to the harmful nature of ultra÷violet
and infra-red arc rays, welding sparks, and welding
fumes and gases
3. FLAMMABLE AND EXPLOSIVE MATERIALS
a Remove flammable and explosive material at least 35
feet from the welding arc to prevent welding sparks
or molten metal from starting a fire Keep a type
ABC fire extinguisher within easy reach.
b, Welding on or near containers which hold combustibles
can cause ar_explosion, even when they have been
cleaned= For information purchase "Safe Practices for
Welding one Cutting Containers that Have Hel d
Combustibles" (A6.0-65_ from the American Welding
:.Society 2501 Northwest Seventh St Miami, Florida

4. PREVENTATIVE MAINTENANCE
a. Never apply power to the welder with any part of the
"cabinet" removed_ Position on-off switch in "Off"
position and disconnect welder from the power
supply before doing maintenance work inside the
machine. Removal of the welder cabinet should be
done only by a qualified service technician,
b.
Before connecting the welder power cord to the
receptacle, check the following:
1 Inspect the power cord and welding cables for cuts
or burns and make sure blades and ground pin on
the plug are straighL
2 Inspect "On-Off" switch lever for cracks or broken
parts.
3 Inspect electrode holder jaw insulators for cracks
or broken parts.
c.
Never weld anything on or to the welder cabinet, as a
burn through may cause transformer failure.

CONNECTING WELDER TO POWER SOURCE
CAUTION: Do not attempt to connect this welder to a
regular household outlet. Make sure the power-line voltage
and frequency agree with the ratings shown on the selector
plate attached to front of eabinet.
Electrical connections between the welder and grounded
230-volt, single-phase, 60-cycle a-c power source should be
made by a qualified electrician. All wiring must comply
with the National Electrical Code (ANSI C1) and local
codes
1. Install an individual (separate) line for the welder with
delayed action type circuit breaker or fuses in the line
For best results, this circuit should be as short as
possible The size of the supply conductors will depend
upon their length as shown in the table below
Supply Conductor (Incl. Extension Cords)
Up to 30 feet ............................ No_ 10 AWG Copper
30 to 50 feet ............................. No 8 AWG Copper
Over 50 feet ................................... No 6 AWG Copper

OPERATnNG CONTROLS
The name "dual range" arc welder is derived from the fact
that your new arc welder is equipped with two separate
welding ranges,
The beginner or less-experienced welder will find the
30-140 amp range easier to use because it provides extra arc
stability when welding with some of the "more difficult to
weld with specialty rods" which are prone to pop-outs
The 40-230 amp range requires less line (input current)
draw for any given amp setting and permits the use of the
maximum amp settings with minimum effect on other'
electrical appliances, motors, and lights, on your electrical
system,
Either range may be used, depending on operator
preferences when the electrode diameter permits
CONNECTING ELECTRODE
AND WORK CABLES
insert the tapered plug on the end of the electrode cable
into the proper outlet jack depending on amperage required
or operator preference.
To insure a good electrical connection always twist the
electrode plug slightly while inserting_ To remove the plug
twist in the opposite direction while removing
NOTE: If you extend the welding cables beyond those
already supplied, they must be No= 4 AWG or larger to
avoid an undue drop in welding current Do not extend
cables over 50 feet,

OPERATING RNSTRUCTIONS
We feel that welding with your new Craftsman dual range
arc welder is assimple asA B C
A Determine what diameter electrode should be used by
gauging the piece to be welded on the material thickness
gauge The fractional number directly beneath the bar
chart dictates what the proper electrode diameter is for
given thicknesses of metals You will note that a specific
diameter of electrodes can be used on varying
thicknesses of material. This is accomplished by
adjusting the heat selector for more or less amperage•
B Next verify the electrode diameter, by placing the bare
portion of the electrode into the electrode diameter
gauge on the right side of the cabinet
Because electrodes are mass produced, there may be
small burrs on the bare ends of the electrode Make sure
the bare end of the rod is as clean as possible for
accurate sizing,
C, Finally, determine the type of electrode by the
identification on the package or by the American
Welding Society number stencilled on the coated portion
of the electrode, bearing in mind the type of electrode
you have chosen - E6013 or E7014, and also its'
diameter (as previously determined)_
Locate that band on the amp scale There are two E6013
bands and two E7014 bands, use the band which
coordinates with the amp range you have selected•
Now loosen the heat selector knob and move the pointer
until the fractional number matching your electrode
diameter appears in the pointer window
Tighten the heat selector knob
Insert the electrode cable into the proper jack
(depending on the range selected), Connect the work
clamp to the work.
Wear Welding Helmet,
Turn the On-Off switch to the "ON" position and you
are ready to weld
Because metals vary in their make up and the technique
of each operator is different, you may find it necessary
to increase or decrease the amperage output accordingly,
CAUTION: Do not loosen and move heat selector while
welding
The duty cycle ratings bracketing the amperage scales are
provided for your convenience and protection of your new
welder_ Duty cycle is the performance level of the welder
based on a 10 minute time span. For example welding for 6
minutes out of 10 minutes is a 60% duty cycle To avoid
possible overheating of the welding transformer, which
could shorten the life of your welder, Do Not exceed the
duty cycles listed on the nameplate

1 Beth edges of the metal
are heated by the arc,
until--
2 they melt and flow to
gether formingone piece,
instantly--
Arc Welding is the process of fusing two or more pieces of
metal together to form one piece. It is accomplished by
heating adjacent metal surfaces to the melting point with an
electric arc, then adding a sufficient amount of molten
metal to provide reinforcement and fill any vacant space
between the parts being joined, as shown in the accompany-
ing illustrations
The arc is created when an electric current, regulated by
a welding transformer, flows across an air gap between an
electrode and the work being welded, The intense heat
generated by the arc is ideally suited for welding, as it
can be directed to affect only the part of the metal to be
welded, Uniform heat from the arc, is acquired by keeping
its length the same for a given rod size and current setting,
At the instant an arc is "struck", a portion of the base
metal directly beneath it, is melted, resulting in a small
pool of molten metal, some of which is forced out by the
blast of the arc and deposited along the weld path, The
depth of the crater thus formed, is the distance the weld
will extend into the base metal and is referred to as the
penetration of the weld
Some of the electrode (which consists of o metal rod sur-
rounded by a flux coating) is melted simultaneously with
the base metal and is carried by the arc to the liquid pool
This added metal combines with the base metal to form
the deposited weld,
3 mere molten metal and
flux is added from the
rod, which-
5 This process continues the entire length of the weld
4 fills the crater andcovers
the top of the weld with
slag,
During th_s operation a part of the flux coating burns off
and forms a gaseous smoke screen that completely en-
velops the arc, protecting the molten metal from harmful
effects of oxygen and nitrogen in the surrounding atmos-
phere, The remainder of the flux coating that melts is
carried to the molten pool where it mixes with the metal
to combine with various impurities It then floats to the
surfaces to form a coating of slag which covers the de-
posited weld metal, protecting it from the atmosphere and
retarding its cooilng
