1.01 Arc Welding Hazards

WARNING

ELECTRIC SHOCK can kill.

Touching live electrical parts can cause fatal shocks
or severe burns. The electrode and work circuit
is electrically live whenever the output is on. The
input power circuit and machine internal circuits
are also live when power is on. In semiautomatic
or automatic wire welding, the wire, wire reel, drive
roll housing, and all metal parts touching the weld­ing wire are electrically live. Incorrectly installed or
improperly grounded equipment is a hazard.

1. Do not touch live electrical parts.

2. Wear dry, hole-free insulating gloves and body protection.

3. Insulate yourself from work and ground using dry insulating
mats or covers.

4. Disconnect input power or stop engine before installing or
servicing this equipment. Lock input power disconnect switch
open, or remove line fuses so power cannot be turned on
accidentally.

5. Properly install and ground this equipment according to its
Owner’s Manual and national, state, and local codes.

6. Turn off all equipment when not in use. Disconnect power to
equipment if it will be left unattended or out of service.

7. Use fully insulated electrode holders. Never dip holder in water
to cool it or lay it down on the ground or the work surface.
Do not touch holders connected to two welding machines
at the same time or touch other people with the holder or
electrode.

8. Do not use worn, damaged, undersized, or poorly spliced
cables.

9. Do not wrap cables around your body.

10. Ground the workpiece to a good electrical (earth) ground.

11. Do not touch electrode while in contact with the work (ground)
circuit.

12. Use only well-maintained equipment. Repair or replace
damaged parts at once.

13. In confined spaces or damp locations, do not use a welder
with AC output unless it is equipped with a voltage reducer.
Use equipment with DC output.

14. Wear a safety harness to prevent falling if working above floor
level.

15. Keep all panels and covers securely in place.

WARNING

ARC RAYS can burn eyes and skin; NOISE can
damage hearing. Arc rays from the welding process
produce intense heat and strong ultraviolet rays that
can burn eyes and skin. Noise from some processes
can damage hearing.

1. Wear a welding helmet fitted with a proper shade of filter (see
ANSI Z49.1 listed in Safety Standards) to protect your face
and eyes when welding or watching.

2. Wear approved safety glasses. Side shields recommended.

ARC MASTER 175 TE SAFETY INSTRUCTIONS

WARNING

FUMES AND GASES can be hazardous to your
health.

Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.

1. Keep your head out of the fumes. Do not breathe the
fumes.

2. If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.

3. If ventilation is poor, use an appro ve d air-s upplied
respirator.

4. Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instruction for metals, consumables,
coatings, and cleaners.

5. Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Shielding gases used for
welding can displace air causing injury or death. Be sure the
breathing air is safe.

6. Do not weld in locations near degreasing, cleaning, or
spraying operations. The heat and rays of the arc can react
with vapours to form highly toxic and irritating gases.

7. Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from
the weld area, the area is well ventilated, and if necessary,
while wearing an air-supplied respirator. The coatings and any
metals containing these elements can give off toxic fumes if
welded.

WARNING

WELDING can cause fire or explosion.

Sparks and spatter fly off from the welding arc.
The flying sparks and hot metal, weld spatter, hot
workpiece, and hot equipment can cause fires and
burns. Accidental contact of electrode or welding
wire to metal objects can cause sparks, overheating,
or fire.

1. Protect yourself and others from flying sparks and hot
metal.

2. Do not weld where flying sparks can strike flammable
material.

3. Remove all flammables within 35’ (10.7m) of the welding
arc. If this is not possible, tightly cover them with approved
covers.

4. Be alert that welding sparks and hot materials from welding
can easily go through small cracks and openings to adjacent
areas.

5. Watch for fire, and keep a fire extinguisher nearby.

6. Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.

7. Do not weld on closed containers such as tanks or drums.

8. Connect work cable to the work as close to the welding area
as practical to prevent welding current from travelling long,
possibly unknown paths and causing electric shock and fire
hazards.

9. Do not use welder to thaw frozen pipes.

produces fumes or gases which contain chemicals
know to the State of California to cause birth defects
and, in some cases, cancer. (California Health &
Safety code Sec. 25249.5 et seq.)

NOTE

Considerations About Welding And The Effects of
Low Frequency Electric and Magnetic Fields

The following is a quotation from the General Conclusions Section
of the U.S. Congress, Office of Technology Assessment, Biological
Effects of Power Frequency Electric & Magnetic Fields - Back­ground Paper, OTA-BP-E-63 (Washington, DC: U.S. Government
Printing Office, May 1989): “...there is now a very large volume
of scientific findings based on experiments at the cellular level
and from studies with animals and people which clearly establish
that low frequency magnetic fields and interact with, and produce
changes in, biological systems. While most of this work is of
very high quality, the results are complex. Current scientific
understanding does not yet allow us to interpret the evidence
in a single coherent framework. Even more frustrating, it does
not yet allow us to draw definite conclusions about questions of
possible risk or to offer clear science-based advice on strategies
to minimize or avoid potential risks.”

To reduce magnetic fields in the workplace, use the following
procedures.

1. Keep cables close together by twisting or taping them.

2. Arrange cables to one side and away from the
operator.

3. Do not coil or drape cable around the body.

4. Keep welding power source and cables as far away from
body as practical.

ABOUT PACEMAKERS:

The above procedures are among those also
normally recommended for pacemaker wearers.
Consult your doctor for complete information.

LEAD WARNING

This product contains chemicals, including lead,
or otherwise produces chemicals known to the
State of California to cause cancer, birth defects
and other reproductive harm. Wash hands after
handling. (California Health & Safety Code §

25249.5 et seq.)

AVERTISSEMENT

LES VAPEURS ET LES FUMEES SONT DANGERE­USES POUR LA SANTE.

Le soudage dégage des vapeurs et des fumées
dangereuses à respirer.

1. Eloignez la tête des fumées pour éviter de les respirer.

2. A l’intérieur, assurez-vous que l’aire de soudage est bien
ventilée ou que les fumées et les vapeurs sont aspirées à
l’arc.

3. Si la ventilation est inadequate, portez un respirateur à ad

-

duction d’air approuvé.

4. Lisez les fiches signalétiques et les consignes du fabricant
relatives aux métaux, aux produits consummables, aux
revêtements et aux produits nettoyants.

5. Ne travaillez dans un espace confiné que s’il est bien ventilé;
sinon, portez un respirateur à adduction d’air. Les gaz pro­tecteurs de soudage peuvent déplacer l’oxygène de l’air et
ainsi causer des malaises ou la mort. Assurez-vous que l’air
est propre à la respiration.

6. Ne soudez pas à proximité d’opérations de dégraissage, de
nettoyage ou de pulvérisation. La chaleur et les rayons de l’arc
peuvent réagir avec des vapeurs et former des gaz hautement
toxiques et irritants.

7. Ne soudez des tôles galvanisées ou plaquées au plomb ou
au cadmium que si les zones à souder ont été grattées à
fond, que si l’espace est bien ventilé; si nécessaire portez
un respirateur à adduction d’air. Car ces revêtements et tout
métal qui contient ces éléments peuvent dégager des fumées
toxiques au moment du soudage.

AVERTISSEMENT

LE SOUDAGE PEUT CAUSER UN INCENDIE OU
UNE EXPLOSION

L’arc produit des étincellies et des projections. Les
particules volantes, le métal chaud, les projections
de soudure et l’équipement surchauffé peuvent
causer un incendie et des brûlures. Le contact ac­cidentel de l’électrode ou du fil-électrode avec un
objet métallique peut provoquer des étincelles, un
échauffement ou un incendie.

parts. To explain the 10 minute duty cycle period
the following example is used. Suppose a Welding
Power Source is designed to operate at a 20% duty
cycle, 175 amperes at 26.8 volts. This means that
it has been designed and built to provide the rated
amperage (175A) for 2 minutes, i.e. arc welding time,
out of every 10 minute period (20% of 10 minutes
is 2 minutes). During the other 8 minutes of the 10

3.01 Environment

These units are designed for use in environments
with increased hazard of electric shock. Examples
of environments with increased hazard of electric
shock are:

A. In locations in which freedom of movement is

restricted, so that the operator is forced to perform
the work in a cramped (kneeling, sitting or lying)
position with physical contact with conductive
parts.

B. In locations which are fully or partially limited by

conductive elements, and in which there is a high
risk of unavoidable or accidental contact by the
operator.

C. In wet or damp hot locations where humidity

or perspiration considerably reduces the skin
resistance of the human body and the insulation
properties of accessories.

Environments with increased hazard of electric shock
do not include places where electrically conductive
parts in the near vicinity of the operator, which can
cause increased hazard, have been insulated.

3.02 Location

Be sure to locate the welder according to the following
guidelines:

• In areas, free from moisture and dust.

• Ambient temperature between 32°F to 104°F
(0°C to 40°C).

• In areas, free from oil, steam and corrosive
gases.

• In areas, not subjected to abnormal vibration or
shock.

• In areas, not exposed to direct sunlight or
rain.

• Place at a distance of 12” (300mm) or more
from walls or similar that could restrict natural
air flow for cooling

!

WARNING

Thermal Arc advises that this equipment
be electrically connected by a qualified
electrician.

3.03 Electrical Input Connections

!

WARNING

ELECTRIC SHOCK can kill; SIGNIFICANT
DC VOLTAGE is present after removal of
input power.

DO NOT TOUCH live electrical parts.

SHUT DOWN welding power source, disconnect input

power employing lockout/tagging procedures. Lock­out/tagging procedures consist of padlocking line
disconnect switch in open position, removing fuses
from fuse box, or shutting off and red-tagging circuit
breaker or other disconnecting device.

• Electrical Input Requirements

Operate the welding power source from a single-phase
50/60 Hz, AC power supply. The input voltage must
match one of the electrical input voltages shown on
the input data label on the unit nameplate. Contact the
local electric utility for information about the type of
electrical service available, how proper connections
should be made, and inspection required. The line
disconnect switch provides a safe and convenient
means to completely remove all electrical power
from the welding power supply whenever necessary
to inspect or service the unit.

Do not connect an input (WHITE or BLACK) conductor
to the ground terminal.

Do not connect the ground (GREEN) conductor to an
input line terminal.

3.04 High Frequency Introduction

The importance of correct installation of high frequency
welding equipment cannot be overemphasized.
Interference due to high frequency initiated or
stabilized arc is almost invariably traced to improper
installation. The following information is intended
as a guide for personnel installing high frequency
welding machines.

!

WARNING:

EXPLOSIVE The high frequency section
of this machine has an output similar to
a radio transmitter. The machine should
NOT be used in the vicinity of blasting
operations due to the danger of premature
firing.

!

WARNING:

COMPUTERS It is also possible that
operation close to computer installations
may cause computer malfunction.

3.05 High Frequency Interference

Interference may be transmitted by a high frequency
initiated or stabilized arc welding machine in the
following ways:

1. Direct Radiation:

Radiation from the machine
can occur if the case is metal and is not properly
grounded. It can occur through apertures such
as open access panels. The shielding of the high
frequency unit in the Power Source will prevent
direct radiation if the equipment is properly
grounded.

2. Transmission via the Supply Lead:

Without
adequate shielding and filtering, high frequency
energy may be fed to the wiring within the
installation (mains) by direct coupling. The
energy is then transmitted by both radiation and
conduction. Adequate shielding and filtering is
provided in the Power Source.

3. Radiation from Welding Leads:

Radiated
interference from welding leads, although
pronounced in the vicinity of the leads, diminishes
rapidly with distance. Keeping leads as short as
possible will minimize this type of interference.
Looping and suspending of leads should be
avoided where possible.

4. Re-radiation from Unearthed Metallic Objects:

A major factor contributing to interference is re­radiation from unearthed metallic objects close
to the welding leads. Effective grounding of such
objects will prevent re-radiation in most cases.

3.06 Electromagnetic Compatibility

!

WARNING

Extra precautions for Electromagnetic
Compatibility may be required when
this Welding Power Source is used in a
domestic situation.

A. Installation and Use - Users Responsibility

The user is responsible for installing and using the
welding equipment according to the manufacturer’s
instructions. If electromagnetic disturbances are
detected then it shall be the responsibility of the user
of the welding equipment to resolve the situation
with the technical assistance of the manufacturer. In
some cases this remedial action may be as simple as
earthing the welding circuit, see NOTE below. In other
cases it could involve constructing an electromagnetic
screen enclosing the Welding Power Source and the
work, complete with associated input filters. In all
cases, electromagnetic disturbances shall be reduced
to the point where they are no longer trouble-some.

NOTE

For 230 VAC operation, have a qualified
person install according to applicable
codes, and instructions.

NOTE

The welding circuit may or may not be
earthed for safety reasons. Changing the
earthing arrangements should only be
authorized by a person who is competent
to assess whether the changes will
increase the risk of injury, e.g. by allowing
parallel welding current return paths which
may damage the earth circuits of other
equipment. Further guidance is given
in IEC 974-13 Arc Welding Equipment ­Installation and use (under preparation).

B. Assessment of Area

Before installing welding equipment, the user shall
make an assessment of potential electromagnetic
problems in the surrounding area. The following shall
be taken into account.

3.07 Setup for Welding

NOTE

Conventional operating procedures apply when using the Welding Power Source, i.e. connect
work lead directly to work piece and electrode lead is used to hold electrode. Wide safety margins
provided by the design ensure that the Welding Power Source will withstand short-term overload
without adverse effects. The welding current range values should be used as a guide only. Current
delivered to the arc is dependent on the welding arc voltage, and as welding arc voltage varies
between different classes of electrodes, welding current at any one setting would vary according to
the type of electrode in use. The operator should use the welding current range values as a guide
then fine tune the welding current to suit the application.

!

WARNING

Before connecting the work clamp to the work and inserting the electrode in the electrode holder
make sure the Primary power supply is switched off.

CAUTION

Remove any packaging material prior to use. Do not block the air vents at the front or rear of the
Welding Power Source.

B. Over Heat Indicator

The welding power source is protected by a self
resetting thermostat. The indicator will illuminate if the
duty cycle of the power source has been exceeded. If
the Over Heat light illuminates wait for the Over Heat
light to extinguish before resuming welding.

C. Trigger Mode Selection Switch (TIG Mode only)
Normal Mode

Press the TIG Torch Trigger Switch and hold depressed
to weld. Release the TIG Torch Trigger Switch to stop
welding. Downslope operates in TIG mode only. Whilst
welding if the TIG Torch Trigger Switch is released, the
welding current ramps down to zero current over a
defined period of time. The time period is determined
by the Downslope Control Knob (F).

Latch Mode

This mode of welding is mainly used for long weld
runs. The operator need only to press the TIG Torch
Trigger Switch to activate and then release the TIG
Torch Trigger Switch to continue to weld, then press
the TIG Torch Trigger Switch again and release the TIG
Torch Trigger Switch to stop welding. This eliminates
the need for the operator to depress the TIG Torch
Trigger Switch for the complete length of the weld.
Downslope operates in TIG Mode only. To activate the
Downslope function in Latch mode whilst welding, the
TIG Torch Trigger Switch must be depressed and held
which will ramp the Welding Current down to zero over
a defined period of time. The time period is determined
by the Downslope Control Knob (F). At any time whilst
welding if the TIG Torch Trigger Switch is depressed
and released the arc will extinguish immediately.

D. Process Selection Switch

Switches between Manual Arc, Lift TIG and HF TIG
modes. Refer to Section 3.08 Setup for Manual Arc
Welding and 3.09 Setup for TIG Welding.

E. Welding Current Control

The welding current is increased by turning the Weld
Current Control Knob clockwise or decreased by
turning the Weld Current Control Knob anticlockwise.
The welding current should be set according to the
specific application. Refer to application notes in this
section for further information.

F. Arc Force/Down Slope Control

Arc Force is effective when in Manual Arc Mode only.
Arc Force control provides an adjustable amount of

Arc Force (or “dig”) control. This feature can be
particularly beneficial in providing the operator the
ability to compensate for variability in joint fit-up
in certain situations with particular electrodes. In
general increasing the Arc Force control toward ‘10’
(maximum Arc Force) allows greater penetration
control to be achieved. Down Slope operates in TIG
mode only. It is used to set the time for weld current
to ramp down. Refer to Item C (Trigger Mode Selection
Switch) for further information regarding Downslope
operation.

G. Gas Outlet

The Gas Outlet is a 5/8-18 UNF female gas fitting and is
utilised for the connection of a suitable TIG Torch.

H. Post Gas Flow

Post Gas Flow is the time Gas flows after the arc
has extinguished. This is used to cool and reduce
oxidisation of the Tungsten Electrode. Post Gas Flow
time is proportional to the Welding Current. For
example if the Welding Current is set to 10 amps the
Post Gas Flow time will be approximately 3 +0/-1
seconds. For a Welding Current set to 175 Amps the
Post Gas Flow time will be approximately 6 +1/-0
seconds. The Post Gas Flow time cannot be adjusted
independently of the Welding Current.

I. Torch Trigger Socket

The 8 pin Torch Trigger Socket is used to connect the
TIG Torch Trigger Switch to the welding Power Source.
To make connections, align keyway, insert plug, and
rotate threaded collar fully clockwise.

Stick electrodes are generally connected to the "+"
Positive Output Terminal and the work lead to the
"−" Negative Output Terminal but if in doubt consult
the electrode manufacturer's literature for further
information.

4.05 Effects of Stick Welding Various
Materials

High Tensile and Alloy Steels

The two most prominent effects of welding these
steels are the formation of a hardened zone in the
weld area, and, if suitable precautions are not taken,
the occurrence in this zone of under-bead cracks.
Hardened zone and under-bead cracks in the weld
area may be reduced by using the correct electrodes,
preheating, using higher current settings, using
larger electrodes sizes, short runs for larger electrode
deposits or tempering in a furnace.

Manganese Steels

The effect on manganese steel of slow cooling from
high temperatures is to embrittle it. For this reason it
is absolutely essential to keep manganese steel cool

during welding by quenching after each weld or skip
welding to distribute the heat.

Cast Iron

Most types of cast iron, except white iron, are
weldable. White iron, because of its extreme
brittleness, generally cracks when attempts are made
to weld it. Trouble may also be experienced when
welding white-heart malleable, due to the porosity
caused by gas held in this type of iron.

Copper and Alloys

The most important factor is the high rate of heat
conductivity of copper, making pre-heating of heavy
sections necessary to give proper fusion of weld and
base metal.

Types of Electrodes

Arc Welding electrodes are classified into a number
of groups depending on their applications. There are
a great number of electrodes used for specialized
industrial purposes which are not of particular interest
for everyday general work. These include some low
hydrogen types for high tensile steel, cellulose types
for welding large diameter pipes, etc. The range of
electrodes dealt with in this publication will cover the

4.06 GTAW Electrode Polarity

Connect the TIG torch to the "-" Negative Output Terminal and the work lead to the "+" Positive Output Terminal

4.14 Joint Preparations

In many cases, it will be possible to weld steel sections without any special preparation. For heavier sections
and for repair work on castings, etc., it will be necessary to cut or grind an angle between the pieces being
joined to ensure proper penetration of the weld metal and to produce sound joints.

In general, surfaces being welded should be clean and free of rust, scale, dirt, grease, etc. Slag should be
removed from oxy-cut surfaces. Typical joint designs are shown in Figure 4-10.

4.15 Arc Welding Technique

A Word to Beginners

For those who have not yet done any welding, the simplest way to commence is to run beads on a piece of
scrap plate. Use mild steel plate about 1/4" (6.0mm) thick and a 1/8" (3.2mm) electrode. Clean any paint, loose
scale or grease off the plate and set it firmly on the work bench so that welding can be carried out in the down
hand position. Make sure that the work clamp is making good electrical contact with the work, either directly
or through the work table. For light gauge material, always clamp the work lead directly to the job, otherwise
a poor circuit will probably result.

OPERATION ARC MASTER 175 TE

Manual 0- 5116 4-9 Operation

4.16 The Welder

Place yourself in a comfortable position before
beginning to weld. Get a seat of suitable height and
do as much work as possible sitting down. Do not
hold your body tense. A taut attitude of mind and a
tensed body will soon make you feel tired. Relax and
you will find that the job becomes much easier. You
can add much to your peace of mind by wearing a
leather apron and gauntlets. You won’t be worrying
then about being burnt or sparks setting alight to
your clothes.

Place the work so that the direction of welding is
across, rather than to or from, your body. The electrode
holder lead should be clear of any obstruction so that
you can move your arm freely along as the electrode
burns down. If the lead is slung over your shoulder,
it allows greater freedom of movement and takes a
lot of weight off your hand. Be sure the insulation on
your cable and electrode holder is not faulty, otherwise
you are risking an electric shock.

4.17 Striking the Arc

Practice this on a piece of scrap plate before going on
to more exacting work. You may at first experience
difficulty due to the tip of the electrode “sticking” to
the work piece. This is caused by making too heavy
a contact with the work and failing to withdraw
the electrode quickly enough. A low amperage will
accentuate it. This freezing-on of the tip may be
overcome by scratching the electrode along the plate
surface in the same way as a match is struck. As soon
as the arc is established, maintain a 1/16" (1.6mm)
to 1/8" (3.2mm) gap between the burning electrode
end and the parent metal. Draw the electrode slowly
along as it melts down.

Another difficulty you may meet is the tendency, after
the arc is struck, to withdraw the electrode so far
that the arc is broken again. A little practice will soon
remedy both of these faults.

Art # A-07696

Figure 4-11: Striking an arc

4.18 Arc Length

The securing of an arc length necessary to produce
a neat weld soon becomes almost automatic. You
will find that A very long arc produces a crackling or
spluttering noise and the weld metal comes across
in large, irregular blobs. The weld bead is flattened
and spatter increases. A short arc is essential if a
high quality weld is to be obtained although if it is
too short there is the danger of it being blanketed by
slag and the electrode tip being solidified in. If this
should happen, give the electrode a quick twist back
over the weld to detach it. Contact or “touch-weld”
electrodes such as E7014 do not stick in this way, and
make welding much easier.

4.19 Rate of Travel

After the arc is struck, your next concern is to maintain
it, and this requires moving the electrode tip towards
the molten pool at the same rate as it is melting away.
At the same time, the electrode has to move along the
plate to form a bead. The electrode is directed at the
weld pool at about 20° from the vertical. The rate of
travel has to be adjusted so that a well-formed bead
is produced.

If the travel is too fast, the bead will be narrow and
strung out and may even be broken up into individual
globules. If the travel is too slow, the weld metal piles
up and the bead will be too large.

4.20 Making Welded Joints

Having attained some skill in the handling of an
electrode, you will be ready to go on to make up
welded joints.

A. Butt Welds

Set up two plates with their edges parallel, as shown in
Figure 4-12, allowing 1/16" (1.6mm) to 3/32" (2.4mm)
gap between them and tack weld at both ends. This
is to prevent contraction stresses from the cooling
weld metal pulling the plates out of alignment. Plates
thicker than 1/4" (6.0mm) should have their mating
edges bevelled to form a 70° to 90° included angle.
This allows full penetration of the weld metal to the
root. Using a 1/8" (3.2mm) E7014 electrode at 120
amps, deposit a run of weld metal on the bottom of
the joint.

Do not weave the electrode, but maintain a steady
rate of travel along the joint sufficient to produce a
well-formed bead. At first you may notice a tendency
for undercut to form, but keeping the arc length short,
the angle of the electrode at about 20° from vertical,
and the rate of travel not too fast, will help eliminate
this. The electrode needs to be moved along fast

ARC MASTER 175 TE OPERATION

Operation 4-10 Manual 0-5116

C. Vertical Welds

1. Vertical Up

Tack weld a three feet length of angle iron

to your work bench in an upright position.
Use a 1/8" (3.2mm) E7014 electrode and
set the current at 120 amps. Make yourself
comfortable on a seat in front of the job
and strike the arc in the corner of the fillet.
The electrode needs to be about 10° from
the horizontal to enable a good bead to be
deposited. Refer Figure 4-16. Use a short arc,
and do not attempt to weave on the first run.
When the first run has been completed de-slag
the weld deposit and begin the second run at
the bottom. This time a slight weaving motion
is necessary to cover the first run and obtain
good fusion at the edges. At the completion of
each side motion, pause for a moment to allow
weld metal to build up at the edges, otherwise
undercut will form and too much metal will
accumulate in the centre of the weld. Figure
4-17 illustrates multi-run technique and Figure
4-18 shows the effects of pausing at the edge
of weave and of weaving too rapidly.

Figure 4-16: Single run vertical fillet weld

Art # A-07702

Figure 4-17: Multi run vertical fillet weld

Art # A-07703

Figure 4-18: Examples of vertical fillet welds

2. Vertical Down

The E7014 electrode makes welding in this

position particularly easy. Use a 1/8" (3.2mm)
electrode at 120 amps. The tip of the electrode
is held in light contact with the work and the
speed of downward travel is regulated so that
the tip of the electrode just keeps ahead of the
slag. The electrode should point upwards at
an angle of about 45°.

3. Overhead Welds

Apart from the rather awkward position

necessary, overhead welding is not much
more difficult that down hand welding. Set
up a specimen for overhead welding by first
tacking a length of angle iron at right angles to
another piece of angle iron or a length of waste
pipe. Then tack this to the work bench or hold
in a vice so that the specimen is positioned in
the overhead position as shown in the sketch.
The electrode is held at 45° to the horizontal
and tilted 10° in the line of travel (Figure 4-

19). The tip of the electrode may be touched
lightly on the metal, which helps to give a
steady run. A weave technique is not advisable
for overhead fillet welds. Use a 1/8" (3.2mm)
E6012 electrode at 120 amps, and deposit the
first run by simply drawing the electrode along
at a steady rate. You will notice that the weld
deposit is rather convex, due to the effect of
gravity before the metal freezes.

4.21 Distortion

Distortion in some degree is present in all forms of welding. In many cases it is so small that it is barely per­ceptible, but in other cases allowance has to be made before welding commences for the distortion that will
subsequently occur. The study of distortion is so complex that only a brief outline can be attempted here.

4.22 The Cause of Distortion

Distortion is cause by:

A. Contraction of Weld Metal:

Molten steel shrinks approximately 11% in volume on cooling to room temperature. This means that a cube
of molten metal would contract approximately 2.2% in each of its three dimensions. In a welded joint, the
metal becomes attached to the side of the joint and cannot contract freely. Therefore, cooling causes the weld
metal to flow plastically, that is, the weld itself has to stretch if it is to overcome the effect of shrinking volume
and still be attached to the edge of the joint. If the restraint is excessive, e.g. a heavy section of plate, then
the weld metal may crack. Even in cases where the weld metal does not crack, there will still remain stresses
“locked-up” in the structure. If the joint material is relatively weak, for example, a butt joint in 5/64" (2.0mm)
sheet, the contracting weld metal may cause the sheet to become distorted.

B. Expansion and Contraction of Parent Metal in the Fusion Zone:

While welding is proceeding, a relatively small volume of the adjacent plate material is heated to a very high
temperature and attempts to expand in all directions. It is able to do his freely at right angles to the surface of
the plate (i.e., “through the weld”), but when it attempts to expand “across the weld” or “along the weld”, it
meets considerable resistance, and to fulfil the desire for continued expansion, it has to deform plastically, that
is, the metal adjacent to the weld is at a high temperature and hence rather soft, and, by expanding, pushes
against the cooler, harder metal further away, and tends to bulge (or is “upset”). When the weld area begins
to cool, the “upset” metal attempts to contract as much as it expanded, but, because it has been “upset”, it
does not resume its former shape, and the contraction of the new shape exerts a strong pull on adjacent metal.
Several things can then happen.

The metal in the weld area is stretched (plastic deformation), the job may be pulled out of shape by the powerful
contraction stresses (distortion), or the weld may crack, in any case, there will remain “locked-up” stresses
in the job. Figures 4-20 and 4- 21 illustrate how distortion is created.

4.23 Overcoming Distortion Effects

There are several methods of minimizing distortion effects.

A. Peening

This is done by hammering the weld while it is still hot. The weld metal is flattened slightly and because of
this the tensile stresses are reduced a little. The effect of peening is relatively shallow, and is not advisable
on the last layer.

ARC MASTER 175 TE OPERATION

Operation 4-12 Manual 0-5116

B. Distribution of Stresses

Distortion may be reduced by selecting a welding
sequence which will distribute the stresses suitably
so that they tend to cancel each other out. See Figures
4-25 through 4-28 for various weld sequences.
Choice of a suitable weld sequence is probably the
most effective method of overcoming distortion,
although an unsuitable sequence may exaggerate it.
Simultaneous welding of both sides of a joint by two
welders is often successful in eliminating distortion.

C. Restraint of Parts

Forcible restraint of the components being welded is
often used to prevent distortion. Jigs, positions, and
tack welds are methods employed with this in view.

D. Presetting

It is possible in some cases to tell from past experience
or to find by trial and error (or less frequently, to
calculate) how much distortion will take place in a
given welded structure. By correct pre-setting of the
components to be welded, constructional stresses
can be made to pull the parts into correct alignment.
A simple example is shown in Figure 4-22.

E. Preheating

Suitable preheating of parts of the structure other
than the area to be welded can be sometimes used
to reduce distortion. Figure 4-23 shows a simple
application. By removing the heating source from B
and C as soon as welding is completed, the sections
B and C will contract at a similar rate, thus reducing

distortion.
