2.08 DUTY CYCLE
The rated duty cycle of a Welding Power Source, is a
statement of the time it may be operated at its rated
welding current output without exceeding the temperature limits of the insulation of the component 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, 200 amperes
at 18.0 volts. This means that it has been designed
and built to provide the rated amperage (200A) 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 minute period the Welding
Power Source must idle and be allowed to cool. The
thermal cut out will operate if the duty cycle is exceeded.

3.05 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 EXPLOSIVES
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 ring.
WARNING Computer
It is also possible that operation close to computer installations may cause computer malfunction. .
3.06 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.
Manual 0-5370
3-2
Installation
INSTALLATION FIREPOWER TIG 200 AC/DC
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 minimise this type
of interference. Looping and suspending of leads should be avoided wherever possible.
4. Re-Radiation from Unearthed Metallic Objects: A major factor contributing to interference is re-radiation from
unearthed metallic objects close to the welding leads. Effective grounding of such objects will prevent re-radiation
in most cases.
3.07 ELECTROMAGNETIC COMPATIBILITY
WARNING
!
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 Troublesome.
Extra precautions for Electromagnetic Compatibility may be required when this Welding Power Source is used
in a domestic situation..
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.
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.
1. Other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the welding
equipment.
2. Radio and television transmitters and receivers.
3. Computer and other control equipment.
4. Safety critical equipment, e.g. guarding of industrial equipment.
5. The health of people around, e.g. the use of pace-makers and hearing aids.
6. Equipment used for calibration and measurement.
7. The time of day that welding or other activities are to be carried out.
8. The immunity of other equipment in the environment: the user shall ensure that other equipment being used
in the environment is compatible: this may require additional protection measures.
The size of the surrounding area to be considered will depend on the structure of the building and other activities
that are taking place. The surrounding area may extend beyond the boundaries of the premises.
Installation
3-3
Manual 0-5370
FIREPOWER TIG 200 AC/DC INSTALLATION
C. Methods of Reducing Electromagnetic Emissions
1. Electricity Supply
Welding equipment should be connected to the Electricity Supply according to the manufacturer’s
recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering
of the Electricity Supply. Consideration should be given to shielding the supply cable of permanently installed
welding equipment in metallic conduit or equivalent. Shielding should be electrically continuous throughout
its length. The shielding should be connected to the Welding Power Source so that good electrical contact is
maintained between the conduit and the Welding Power Source enclosure.
2. Maintenance of Welding Equipment
The welding equipment should be routinely maintained according to the manufacturer’s recommendations. All
access and service doors and covers should be closed and properly fastened when the welding equipment is in
operation. The welding equipment should not be modified in any way except for those changes and adjustments
covered in the manufacturer’s instructions.
3. Welding Cables
The welding cables should be kept as short as possible and should be positioned close together but never
coiled and running at or close to the floor level.
4. Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it should be considered. However,
metallic components bonded to the work piece will increase the risk that the operator could receive a shock by
touching the metallic components and the electrode at the same time. The operator should be insulated from
all such bonded metallic components.
5. Earthing/grounding of the Work Piece
Where the work piece is not bonded to earth for electrical safety, nor connected to earth because of its size
and position, e.g. ship’s hull or building steelwork, a connection bonding the work piece to earth may reduce
emissions in some, but not all instances. Care should be taken to prevent the earthing of the work piece
increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connection
of the work piece to earth should be made by direct connection to the work piece, but in some countries where
direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected according
to national regulations.
6. Screening and Shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems
of interference. Screening the entire welding installation may be considered for special applications.

digital displays if either of the following two conditions exists
Manual 0-5370
3-6
Installation
INSTALLATION FIREPOWER TIG 200 AC/DC
1. Thermal Overload
This is due to the duty cycle of the power source being exceeded. Once the power source cools sufficiently
it will automatically reset and the Fault Indicator and Err 001 will go off and the power source is then able
to continue welding. During the time of cooling the power source should remain ON such that the fan
continues to operate allowing the unit to cool sufficiently. If after 30 minutes with the fan running the Fault
Indicator has not gone OFF then have an Accredited Firepower Service Provider check the power source.
2. Primary Circuit Overcurrent
This is due to primary circuit component(s) malfunctioning which results in excessive primary circuit
current. Switch OFF the power source immediately to allow all components to cool down for at least 30
minutes. If after 30 minutes “Err 001” is displayed and Fault Indicator illuminates when the power source
is switched back ON turn the power source OFF and have an Accredited Firepower Service Provider check
the power source.
7. Process Selection Switch
The process selection control is used to select the desired welding mode. Three modes are available, GTAW
(LIFT TIG), GTAW (HF TIG) and SMAW (Stick) modes.
Note that when the unit is powered off the mode selection control will automatically default to LIFT TIG mode.
This is necessary so as to prevent inadvertent arcing should an electrode holder be connected to the unit and
mistakenly be in contact with the work piece during power up.
8. Trigger Mode Control Switch (HF TIG and LIFT TIG Mode only)
The trigger mode control is used to switch the functionality of the torch trigger between 2T (normal), and 4T
(latch mode).
2T Normal Mode
In this mode, the torch trigger must remain depressed for the welding output to be active. Press and hold the
torch trigger to activate the power source (weld). Release the torch trigger switch to cease welding.
NOTE!
When operating in GTAW (HF and LIFT TIG modes), the power source will remain active until the selected down slope time
has elapsed.

16. Programming Parameter Indicators (Front Panel Display Indicators)
The Front Panel LED indicators serve two purposes. First, they show what process and what parameter is
selected and the value of that parameter. The AMP DISPLAY shows only amperage values measured in AMPS,
the VOLT DISPLAY can indicate Voltage, Time, Percentage, or Frequency. The UNITES lights indicate the unit
of measurement for the reading on the VOLT DISPLAY: Volts (V), Seconds (SEC), Percent (%),Hertz (HZ). Only
the parameters that are applicable to a specific PROCESS, MODE, or TRIGGER SELECTION will light when
using the FORWARD or BACK programming switches. Secondly, during the welding process, the following
sequence indicators will light to indicate the specific phase of the weld process which is active:

17. Mode Switch
Press the MODE switch to toggle AC and DC output in all Process modes
18. Digital Ammeter
The digital amperage meter is used to display both the pre-set current and actual output current of the power
source.
At times of non-welding, the amperage meter will display a pre-set (preview) amperage value. This value can
be adjusted by varying the multifunction control when the Programming Parameter Indicator light shows
WELD CURRENT.
NOTE: You will not be able to view the pre-set amperage on the power source with this control, amperage will
not be viewable until the arc is initiated. The all-in-one on/off with rotary current control cannot provide preview.
When welding, the amperage meter will display actual welding current.
Should a remote device be connected the maximum setting of the power source will be determined by the
respective front panel control, irrespective of the remote control device setting. As an example, if the output
current on the power source front panel is set to 50% and the remote control device is set to 100%, the
maximum achievable output from the unit will be 50%. Should 100% output be required, the respective power
source front panel control must be set to 100%, in which case the remote device will then be able to control
between 0-100% output.

Size of Electrode
The electrode size is determined by the thickness of metals being joined and can also be governed by the type
of welding machine available. Small welding machines will only provide sufficient current (amperage) to run the
smaller size electrodes.
For thin sections, it is necessary to use smaller electrodes otherwise the arc may burn holes through the job. A
little practice will soon establish the most suitable electrode for a given application.
Storage of Electrodes
Always store electrodes in a dry place and in their original containers.
Electrode Polarity
Electrodes are generally connected to the ELECTRODE HOLDER with the Electrode Holder connected positive
polarity. The WORK LEAD is connected negative polarity and is connected to the work piece. If in doubt consult
the electrode data sheet or your nearest Accredited Firepower Distributor.
Effects of Stick Welding Various Materials
A. 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.
B. 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.
C. 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.
D. 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.
E. 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 vast
majority of applications likely to be encountered; are all easy to use.

metal. Its soft arc has minimal spatter, moderate penetration and
an easy-to-clean slag.
Mild Steel E7014 All positional, ease to use electrode for use on thicker steel than
E6013. Especially suitable sheet metal lap joints and fillet welds,
general purpose plate welding.
Mild Steel E7018 A low-hydrogen, all-position electrode used when quality is an
issue or for hard-to-weld metals. It has the capability of producing
more uniform weld metal, which has better impact properties at
low temperatures.

Welding Position
The electrodes dealt with in this publication can be used in most positions, i.e. they are suitable for welding in
flat, horizontal, vertical and overhead positions. Numerous applications call for welds to be made in positions
intermediate between these. Some of the common types of welds are shown in Figures 4-5 through 4-12.

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 4-9.

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 downhand
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.
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.
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.
Be sure the insulation on your cable and electrode holder is not faulty, otherwise you are risking an electric shock.
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_AB
Figure 4-10: Striking an Arc
Arc Length
The securing of an arc length necessary to produce a neat weld soon becomes almost automatic. You will find
that a long arc produces more heat. 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.
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 20º 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.

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 4-11, 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 70º to 90º included angle. This allows full penetration of the weld metal to the root.
Do not weave the electrode, but maintain a steady rate of travel along the joint sufficient to produce a wellformed 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 20º from vertical, and the rate of travel not too fast, will help eliminate this.
The electrode needs to be moved along fast enough to prevent the slag pool from getting ahead of the arc.
To complete the joint in thin plate, turn the job over, clean the slag out of the back and deposit a similar weld.

Figure 4-11: Butt Weld
Art # A-07698
Figure 4-12: Weld Build up Sequence
Heavy plate will require several runs to complete the joint. After completing the first run, chip the slag out and
clean the weld with a wire brush. It is important to do this to prevent slag being trapped by the second run.
Subsequent runs are then deposited using either a weave technique or single beads laid down in the sequence
shown in Figure 4-12. The width of weave should not be more than three times the core wire diameter of the
electrode. When the joint is completely filled, the back is either machined, ground or gouged out to remove slag
which may be trapped in the root, and to prepare a suitable joint for depositing the backing run. If a backing
bar is used, it is not usually necessary to remove this, since it serves a similar purpose to the backing run in
securing proper fusion at the root of the weld.

B. Fillet Welds
These are welds of approximately triangular crosssection made by depositing metal in the corner of
two faces meeting at right angles. Refer to Figure
4-4.
A piece of angle iron is a suitable specimen with
which to begin, or two lengths of strip steel may
be tacked together at right angles. This is known
as a horizontal-vertical (HV) fillet. Strike the arc
and immediately bring the electrode to a position
perpendicular to the line of the fillet and about
45º from the vertical. Some electrodes require to
be sloped about 20º away from the perpendicular
position to prevent slag from running ahead of
the weld. Refer to Figure 4-13. Do not attempt
to build up much larger than 1/4" (6.4mm) width
with a 1/8" (3.2mm) electrode, otherwise the weld
metal tends to sag towards the base, and undercut
forms on the vertical leg. Multi-runs can be made
as shown in Figure 4-14. Weaving in HV fillet welds
is undesirable.
45° from
vertical
C. Vertical Welds
1. Vertical Up
Tack weld a three feet length of angle iron to
your work bench in an upright position. 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 10º from
the horizontal to enable a good bead to be
deposited. Refer Figure 4-15. 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
4-16 illustrates multi-run technique and Figure
4-17 shows the effects of pausing at the edge
of weave and of weaving too rapidly.

2. Vertical Down
Use a 1/8" (3.2mm) electrode at 100 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 45º.
3. Overhead Welds
Apart from the rather awkward position necessary, overhead welding is not much more difficult that
downhand 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 45º to the horizontal and tilted 10º in the line of travel (Figure 4-18). 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.

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 hear.

The Cause of Distortion
Distortion is caused by:
A. Contraction of Weld Metal:
Molten steel shrinks approximately 11 per cent
in volume on cooling to room temperature. This
means that a cube of molten metal would contract
approximately 2.2 per cent 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 very great, as, for example, in a heavy
section of plate, 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 this 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 4-19 and
4- 20 illustrate how distortion is created.

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.
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 4-20 through 4-23 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 4-21.

Art # A-07711_AB
E. Preheating
Suitable preheating of parts of the structure other
than the area to be welded can be sometimes used
to reduce distortion. Figure 4-22 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.

Gas Tungsten Arc Welding (GTAW) or TIG (Tungsten Inert Gas) as it is commonly referred to, is a welding process
in which fusion is produced by an electric arc that is established between a single tungsten (non-consumable)
electrode and the work piece. Shielding is obtained from a welding grade shielding gas or welding grade shielding
gas mixture which is generally Argon based. A filler metal may also be added manually in some circumstances
depending on the welding application.

FAULT CAUSE REMEDY
Error Code “Err 001” is
displayed on the digital
displays in conjunction
with the Fault Indicator
Illuminating.
A. Thermal Overload This is due to the duty cycle of
the power source being exceeded.
Once the power source cools
sufficiently it will automatically
reset and the Fault Indicator and
Err 001 will go off and the power
source is then able to continue
welding. During the time of
cooling the power source should
remain ON such that the fan
continues to operate allowing the
unit to cool sufficiently. If after 30
minutes with the fan running the
Fault Indicator has not gone OFF
then have an Accredited Firepower
Service Provider check the power
source.
B.
Primary Circuit Overload This is due to primary circuit
component(s) malfunctioning
which results in excessive primary
circuit current. Switch the power
source to OFF immediately to
allow all components to cool
down for at least 30 minutes.
If after 30 minutes “Err 001” is
displayed and Fault Indicator
illuminates when the power
source is switched back ON turn
the power source OFF and have
an Accredited Firepower Service
Provider check the power source.
