material contained inside for shielding.
Gas Metal Arc Welding (GMAW) -
also called MIG, is a welding process
used with a wire feed welding machine.
The wire is solid and an inert gas is used
for shielding.
Spatter - metal particles thrown from
the weld which cool and harden on the
work surface. Spatter can be minimized
by using a spatter resistant spray on the
work piece before welding.
Arc Length - the distance from the
end of the electrode to the point where
the arc makes contact with the work
surface.

from 5º to 45º depending on welding
conditions.
Butt Joint - a joint between two
members aligned approximately in the

Lap Joint - a joint between two
overlapping members in parallel planes.
Crater - a pool, or pocket, that is
formed as the arc comes in contact with
the base metal.
T Joint - made by placing the edge of
one piece of metal on the surface of
the other piece at approximately a 90º
angle.
Open Circuit Voltage (OCV) - the
voltage between the electrode and the
work clamp of the welding machine
when no current is flowing (not
welding). The OCV determines how
quickly the arc is struck.
DC or Direct Current - electric current
which flows only in one direction.
The polarity (+ or -) determines which
direction the current is flowing.
Undercut - a condition that results
when welding amperage is too high.
The excessive amperage leaves a groove
in the base metal along both sides of
the bead which reduces the strength of
the weld.
DC Reverse Polarity - occurs when the
electrode holder is connected to the
positive pole of the welding machine.
Reverse Polarity directs more heat
into melting the electrode rather than
the work piece. It is used on thinner
material.
Overlap - occurs when the amperage is
set too low. In this instance, the molten
metal falls from the electrode without
actually fusing into the base metal.
Weld Pool or Puddle - a volume of
molten metal in a weld prior to its
solidification as weld metal.
Porosity - gas pockets, or cavities,
formed during weld solidification. They
weaken the weld.
Weld Bead - a narrow layer or layers of
metal deposited on the base metal as
the electrode melts. Weld bead width
is typically twice the diameter of the
electrode.
DC Straight Polarity - occurs when
the electrode holder is connected to the
negative pole of the welding machine.
With straight polarity more heat is
directed to the work piece for better
penetration on thicker material.
Penetration - the depth into the work
piece that has been heat effected by
the arc during the welding process. A
good weld achieves 100% penetration
meaning that the entire thickness of
the work piece has been heated and
resolidified. The heat effected area
should be easily seen on the opposite
side of the weld.
Work Angle - the angle of the
electrode from horizontal, measured at
right angles to the line of welding.
Electrode - a coated metal wire having
approximately the same composition as
the material being welded.
Fillet Weld - approximately a triangle
in cross-section, joining two surfaces at
right angles to each other in a lap, T or
corner joint.
Shielded Metal Arc Welding
(SMAW) - also called Stick, is a welding
process that uses a consumable
electrode to support the arc. Shielding
is achieved by the melting of the flux
coating on the electrode.
Flux - a coating, when heated, that
produces a shielding gas around the
welding area. This gas protects the
parent and filler metals from impurities
in the air.

the 120 volt receptacles.
If actual watt ratings are not available,
the Power Usage Chart, see Table 1, may
be used as a general guideline.
Pre-Operation (Continued)
LOW OIL SHUTDOWN
A low oil shutdown switch is provided
to protect the engine and welder /
generators on most extended run
models. When engine oil level drops
too low for proper engine operation,
the low oil shutdown switch causes the
engine to shut off. If oil level is low
when attempting to start the welder /
generators engine, the low oil level
shutdown switch prevents the engine
from starting. If engine does not start,
check oil level.
The 120/240 volt twist lock
receptacle, found on some welder /
generators, is rated for 20 amps and incandescent light bulbs, motors and
may be used in any combination of
120 volt and 240 volt loads.
Remember that devices which generate
heat during operation such as heaters,
hair dryers have a higher power draw
than devices which generate little heat
during operation such as florescent
bulbs, radios, and clocks.
4. Individual receptacles should not
be loaded beyond the amperage
rating.
Long power cords and extension cords
also draw additional power. Keep cords
at minimum possible length.
5. Total combined load through any
combination of receptacle must
not exceed the rated load limits of
the welder / generator. Refer to the
identification plate on the welder /
generators for amp and wattage
specifications.
Refer to Table 2 for maximum limits for
lengths of extension cords.
NOTE: It is important to keep the
welder / generator unit on a level
surface. The oil level shutdown switch
can prevent the engine from starting
even if oil level is sufficient, when the
welder / generators unit is placed on an
uneven surface.
8. Circuit protection is provided by a
circuit breaker. The circuit breaker
opens when the welder / generator
load exceeds its maximum capacity
or a short circuit occurs. If the
circuit breaker opens, perform the
following procedures to correct the
problem:
6. Always shut off and remove loads
before starting or shutting off the
welder / generator engine.

DINSE PLUGS (SEE FIGURE 3)
1. Strip 1/2 inch of insulation from the
opposite end of the welding cable.
3. Insert the exposed part of the
electrode (the end with no flux)
into the jaws of the electrode
holder.
4. Pull the starter cord several times
to spread the oil throughout the
cylinder.
2. Insert this end of the welding cable
through the dinse plug boot and
slide the bare wire into the wire
sleeve.
4. Set the amperage adjustment knob
to the proper amperage for the
electrode diameter. Refer to the
chart on the front panel for proper
electrode current settings.
5. Slowly pull the starter cord, until
resistance is felt. This indicates that
the piston is moving upward on the
compression cycle, and the intake
and exhaust valves are closed. (The
piston pushes a small amount of
air from the spark plug hole on
compression.)
3. Insert the welding cable/wire sleeve
assembly into the back of the dinse
plug.
The electrode holder

5. Slide the boot over the hex portion
of the dinse plug.
5. Position the electrode to begin
weld, lower the welding helmet or
position the hand shield, and strike
an arc. Adjust weld amperage as
needed.
6. Use of fuel stabilizers or anti-
gumming agents in the fuel system
can help prevent the build up of
gum and varnish.

STRIKING AN ARC
3. E-7014 Fast fill
Welding Guidelines
GENERAL
Place the bare end of the electrode in
the holder. Grip the holder lightly to
reduce tiring of the hand and arm.
•
•
Smooth bead and fast deposition
This line of welding machines utilizes
a process known as Shielded Metal-Arc
Welding (SMAW). This process is used
to bond metals by heating them with
an electric arc created between the
electrode and the work piece.
Ideal for joints with poor fitup and
general repair work.
NOTE: Always keep the jaws of the
holder clean to insure good electrical
contact with the electrode.
4. E-7018-AC High Strength
•
Ideal for pipes and structural
applications.
Be careful not to
touch the work piece
•
Low hydrogen reduces porosity for
a strong weld.
Electrodes used for shielded metal arc
welding have two parts. The inner
core is a metal rod or wire that should
be similar in composition to the base
metal. The outer coating is called
flux. Various types of flux exist. Each
coating is used for a particular welding
situation.
or welding bench with the electrode as
this causes arc flashes.
NOTE: Only the E-7018-AC electrode
is recommended for use with these
welders. Other E-7018 electrodes are
designed for use with higher open
circuit voltages than these welders are
capable of producing. Recommended
electrode diameter is 3/32 inch or 1/8
inch.
The best method of striking an arc is the
scratching method. Drag the electrode
at an angle along the surface much like
striking a match. Upon contact with the
plate, lift the electrode approximately
1/16” off the surface or it will stick (See
Figure 5).
While the metal is molten, it can be
contaminated by elements in the air.
This contamination could weaken
the weld. The flux coating creates
a protective barrier called slag that
protects the molten metal from
contaminants.
NOTE: Should the electrode stick to the
work piece, break it loose by quickly
twisting or bending at the holder
while pulling upward. If the electrode
does not break loose, disengage the
electrode by releasing it from the
holder.
ARC WELDING BASICS
Four basic techniques affect weld
quality. These are: amperage setting,
weld angle, arc length, and travel
speed. Proper use of these techniques is
necessary for good weld quality.
When current (amperage) flows
through the circuit to the electrode, an
arc is formed between the end of the
electrode and the work piece. The arc
melts the electrode and the work piece.
The melted metal of the electrode flows
into the molten crater and forms a bond
with the work piece as shown in
Figure 4.
AMPERAGE SETTING
The correct amperage involves the
adjustment of the welding machine
to the required amp setting. This is
regulated by a knob on the welder. The
amperage required depends on the size
(diameter) of electrode used and the
thickness of the work piece.
1/16 inch
NOTE: Discontinue using and discard
electrodes that burn down to 1 to 2
inches from the electrode holder.
Same as Electrode Diameter
Consult specifications listed on the
welder. Excessive amps burn through
light metals and the weld bead is flat
and porous (See Figure 7). The bead
appears high and irregular if the
amperage is too low.
Figure 5 - Scratching Method
Wire
ELECTRODE TYPE AND SIZE
Four types of electrodes are
Flux
recommended for this welder. The
electrodes are commonly known by
the AWS (American Welding Society)
designation as follows:
WELD ANGLE
Slag
Weld
Weld angle is the angle at which the
electrode is held during the welding
process. Using the correct angle
ensures proper penetration and bead
formation. Electrode angle involves
two positions - travel angle and work
angle (See Figure 6).

Travel angle is the angle in the line
of welding and may vary from 5º to
45º from the vertical, depending on
welding conditions.

GW4500
an arc does not create enough heat to
melt the work piece, the electrode has
a tendency to stick, penetration will be
poor, and uneven beads with irregular
ripples result. A proper arc should be no
longer than the diameter of the rod.
Welding Guidelines
(Continued)
Work angle is the angle from
horizontal, measured at right angles to
the line of welding.
5º - 45º
For most applications, a 45º travel
angle and 45º work angle is sufficient.
For specific applications, consult an arc
welding handbook.
The sound of a proper arc is a steady,
crisp sizzle, similar to bacon frying.
Travel Angle
TRAVEL SPEED
NOTE: Right handed welders should
weld from left to right. Left handed
welders should weld from right to left.
The electrode should always point into
the weld puddle as shown.
The travel speed is the rate at which
the electrode is moved across the weld
area (See Figure 7). When the speed is
too fast, the bead is narrow and bead
ripples are pointed as shown. When the
speed is to slow, the weld metal piles
up and the bead is high and wide. To
control travel speed, watch the width
of the weld bead (not the arc) when
welding. The weld bead is the orange,
molten metal behind the arc. The width
should be approximately twice the
diameter of the welding rod. Control
travel speed to obtain a consistent bead
width.
ARC LENGTH
Arc length is the distance from the
work piece to the tip of the electrode,
the distance which the arc must travel.
A proper arc length is essential to
generate the heat needed for welding
(See Figure 7). An arc that is too long
produces an unstable arc, reduces
penetration, increases spatter, and
causes flat and wide beads. Too short

SLAG REMOVAL
Wear ANSI approved
safety glasses (ANSI
Standard Z87.1) and protective clothing
when removing slag. Hot, flying debris
can cause personal injury to anyone in
the area.
For testing of rotor,
WELD PASS
stator, or field
windings, consult an authorized service
center.
Sometimes more then one pass is
necessary to fill the joint. The root pass
is first, followed by filler passes and the
cover pass (See Figures 8 and 9). If the
pieces are thick, it may be necessary to
bevel the edges that are joined at a 60º
angle. Remember to remove the slag
before each pass.
After completing the weld, wait for the
welded sections to cool. A protective
coating called slag now covers the weld
bead which prevents contaminants in
the air from reacting with the molten
metal. Once the weld cools to the point
that it is no longer glowing red, the slag
can be removed. Removal is done with
a chipping hammer. Lightly tap the slag
with the hammer and break it loose
from the weld bead. The final clean-up
is done with a wire brush. When making
multiple weld passes, remove the slag
before each pass.
TESTING WELDER / GENERATOR
DIODES
The following method eliminates the
need to disconnect the diodes from the
welder / generators wiring.
1. Use a 12 Volt battery and
automotive lamp (Type 5001) to
test the diodes in the welder /
generators.
WELDING POSITIONS
2. Connect the battery and lamp as
shown in Figure 10.
Four basic welding positions can be
used; flat, horizontal, vertical, and
overhead. Welding in the flat position
is easier than any of the others because
welding speed can be increased, the
molten metal has less tendency to run,
better penetration can be achieved, and
the work is less fatiguing.
3. If the diodes are operating
properly, the lamp illuminates
brightly when the battery polarity is
correct, and goes dim when battery
polarity is reversed.
Other positions require different
techniques such as a weaving pass,
circular pass, and jogging. A higher
skill level is required to complete these
welds.
