SERVICE MANUAL
WARNING
WARNING
FUMES AND GASES can be hazardous to
your health.
ARC RAYS can burn eyes and skin; NOISE
can damage hearing.
Welding produces fumes and gases.
Breathing these fumes and gases can be
hazardous to your health.
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. Keep your head out of the fumes. Do not breath
the fumes.
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. If inside, ventilate the area and/or use exhaust at
the arc to remove welding fumes and gases.
2. Wear approved safety glasses. Side shields
recommended.
4. Read the Material Safety Data Sheets (MSDSs)
and the manufacturer’s instruction for metals,
consumables, coatings, and cleaners.
3. Use protective screens or barriers to protect others
from flash and glare; warn others not to watch
the arc.
4. Wear protective clothing made from durable,
flame-resistant material (wool and leather) and
foot protection.
5. Use approved ear plugs or ear muffs if noise level
is high.
3. If ventilation is poor, use an approved air-supplied
respirator.
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 vapors 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 airsupplied 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 ft (10.7 m) 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 traveling long, possibly unknown
paths and causing electric shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off
welding wire at contact tip when not in use.
WARNING
FLYING SPARKS AND HOT METAL can
cause injury.

1. Wear approved face shield or safety goggles. Side
shields recommended.
2. Wear proper body protection to protect skin.
WARNING
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under
high pressure. If damaged, a cylinder can
explode. Since gas cylinders are normally
part of the welding process, be sure to
treat them carefully.
1. Protect compressed gas cylinders from excessive
heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position
by chaining them to a stationary support or
equipment cylinder rack to prevent falling or
tipping.
3. Keep cylinders away from any welding or other
electrical circuits.
4. Never allow a welding electrode to touch any
cylinder.
5. Use only correct shielding gas cylinders,
regulators, hoses, and fittings designed for the
specific application; maintain them and associated
parts in good condition.
6. Turn face away from valve outlet when opening
cylinder valve.
7. Keep protective cap in place over valve except

1.02 PRINCIPAL SAFETY STANDARDS
WARNING
This product, when used for welding or
cutting, 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 sciencebased advice on strategies to minimize or avoid
potential risks.”
To reduce magnetic fields in the workplace, use the

3.01 Environment
The Transtig 200 AC/DC is designed for use in
hazardous environments. Examples of environments
with increased hazardous conditions 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, or
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.
!
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.
Environments with hazardous conditions 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 0 degrees C to
40 degrees 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” (304.79mm) or more
from walls or similar that could restrict natural
airflow for cooling.

3.05 High Frequency Introduction
3.06 High Frequency Interference
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.
Interference may be transmitted by a high frequency
initiated or stabilized arc welding machine in the
following ways:
!
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 firing.
!
WARNING: COMPUTERS
It is also possible that operation close to
computer installations may cause
computer malfunction.
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.

TRANSTIG 200 AC/DC
SERVICE MANUAL
3.07 Duty Cycle
The duty cycle of a welding power source is the
percentage of a ten (10) minute period that it can be
operated at a given output without causing
overheating and damage to the unit. If the welding
amperes decrease, the duty cycle increases. If the
welding amperes are increased beyond the rated
output, the duty cycle will decrease.
!
WARNING
Exceeding the duty cycle ratings will cause
the thermal overload protection circuit to
become energized and shut down the
output until the unit has cooled to normal
operating temperature.
3-4
CAUTION
Continually exceeding the duty cycle
ratings can cause damage to the welding
power source and will void the
manufacturer's warranty.
NOTE
Due to variations that can occur in
manufactured products, claimed
performance, voltages, ratings, all
capacities, measurements, dimensions
and weights quoted are approximate only.
Achievable capacities and ratings in use
and operation will depend upon correct
installation,
use,
applications,
maintenance and service.

SET-UP FOR SMAW (STICK) AND GTAW (TIG)
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
coil 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 finally adjust the current setting 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.

The Pulse controls are used primarily to control heat input. Pulse offers a number of advantages as follows:
1) Control puddle – size and fluidity (especially out of position).
2) Increase penetration
3) Travel speed control
4) Better consistent quality
5) Decreased distortion on lighter or thinner materials
Pulse-current provides a system in which the welding current continuously changes between two levels.
During the periods of Peak current, heating and fusion takes place, and during the background (base) current
periods, cooling and solidification take place. Pulse Width is the time in one cycle the current remains at the
peak current setting. Pulse Frequency, measured in Hertz, is the number of cycles per second the current
travels between peak and background current settings. It is as if the foot rheostat were moved up and down
to increase and decrease the welding current on a regular basis. The faster you moved the foot rheostat up
and down the faster the frequency.

BASIC TIG WELDING GUIDE
7.01 Explanation of “Fluttery Arc”
when AC TIG Welding on
Aluminum
The following will assist in understanding the
phenomenon of Arc Flutter, also referred to as Arc
Rectification.
The basic thesis is that the fluttering is caused by
lack of oxide in the weld pool.
The oxide layer on the plate reduced the energy for
electron emission. Electron emission from the weld
pool (DC+) causes the oxide layers to be disrupted,
the so-called “cleaning action”. However once the
cleaning action has produced a mirror like surface on
the weld pool, the effect of the oxide layer is limited
because the oxide layer has dissipated. This makes
electron emission from the weld pool more difficult
and increases the chance of arc instability.
This idea is supported by the observation that once
fluttering starts it can be made to stop by working
the arc away from the mirror like weld pool to an area
of oxide coated material. As soon as this is done the
arc settles back to a stable condition. So while the
arc is “consuming” oxide coated plate the instability
does not occur. But once the arc is stationary, the
pool becomes thoroughly “cleaned” by election
emission, the fluttering begins.
Tests conducted on various types of AC TIG power
sources, Fluttery Arc is not confined to one type of
power source or its' design, both conventional and
inverter types suffer from the same problem.
AC TIG on aluminum
1. The Problem: Arc appears unstable and pulses or flutters. ie. appears to rapidly change welding current.
Conditions that accentuate arc flutter:
Conditions that minimizes arc flutter:
• Cold work piece
• Preheat the work piece
• Very short arc length
• Increase the arc length
• Weld pool crater about 0.39” to 0.47”
(10 to 12mm) diameter
• Introduce filler rod material to the weld
pool, which introduces oxides
• Arc field in one spot to produce
“mirror” clean weld pool
• Move the weld pool around to introduce
oxides to the weld pool
• Increased cleaning action
i.e. Prolonged oxide emission from a
stationary weld pool increases the
likelihood of arc flutter
• Decrease the cleaning action by turning
the WAVE BALANCE to below 50% or
move the weld pool around
• Accentuated when tungsten running
near its current capacity, i.e. Molten ball
on end
• Use a larger diameter tungsten electrode
Table 7-1: Reduction of Arc Flutter
2. Conclusion: Fluttery Arc in AC TIG is a physical phenomenon independent of machine design.

BASIC ARC WELDING GUIDE
8.01 Electrode Polarity
Types of Electrodes
Stick electrodes are generally connected to the ‘+’
terminal and the work lead to the ‘-’ terminal but if in
doubt consult the electrode manufacturers literature.
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 and all will work on even the most
basic of welding machines.
8.02 Effects of Stick Welding Various
Materials
High Tensile and Alloy Ateels
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 whiteheart 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 preheating of heavy
sections necessary to give proper fusion of weld and
base metal.

12.00 Introduction
12.01 System-Level Fault Isolation
If you are here, all of the troubleshooting suggestions in Section 5 Basic Troubleshooting have either
failed to resolve the faulty operation or have indicated
that one or more of the subsystems within the power
supply are defective. This section provides the information needed to take live measurements on the various subsystems within the power supply, and replace
those subsystems that prove faulty.
If none of the suggestions provided in Section 5 have
solved the problem or corrected the faulty operation,
the next step is to isolate one or more of the internal
subassemblies that may be defective.
CAUTION
Troubleshooting and repairing this unit is
a process, which should be undertaken
only by those familiar with high voltage/
high power electronic equipment.
!
WARNING
CAUTION

There are extremely dangerous voltage
and power levels present inside this unit.
Do not attempt to diagnose or repair unless you have training in power electronics, measurement and troubleshooting
techniques.
Under no circumstances are field repairs to be attempted on printed circuit boards or other subassemblies of this unit. Evidence of unauthorized repairs
will void the factory warranty. If a subassembly is
found to be defective by executing any of the procedures in this Service Manual, the subassembly should
be replaced with a new one. The faulty subassembly
should then be returned to Cigweld through established procedures.

APPENDIX 3 DIODE TESTING BASICS
DIODE TESTING BASIC
APPENDIX 4 DIODE TESTING BASIC
Testing of diode modules requires a digital Volt/
Ohmmeter that has a diode test scale.Locate the
diode module to be tested.Remove cables from
mounting studs on diodes to isolate them within the
module.Set the digital volt/ohm meter to the diode
test scale.Using figure 1 and 2, check each diode
in the module. Each diode must be checked in both
the forward bias (positive to negative) and reverse
bias (negative to positive) direction.
VR
1. To check the diode in the forward bias direction, connect the volt/ohm meter positive lead
to the anode (positive, +) of the diode and the
negative lead to the cathode (negative, –) of
the diode (refer to Figure 13-1. A properly
functioning diode will conduct in the forward
bias direction, and will indicate between 0.3
and 0.9 volts.
2. To check the diode in the reverse bias direction, reverse the meter leads (refer to Figure
13-1). A properly functioning diode will block
current flow in the reverse bias direction, and
depending on the meter function, will indicate
an open or "OL".
