GENERAL INFORMATION 1-2 Manual 0-5207
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 breath
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 approved air-supplied
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.
WELDSKILL 200AC/DC INVERTER
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 travelling 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
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 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 con
tact 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.
FLYING SPARKS AND HOT METAL can
cause injury.
Chipping and grinding cause flying metal.
As welds cool, they can throw off slag.
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.
Manual 0-5207 1-3 GENERAL INFORMATION
WELDSKILL 200 AC/DC INVERTER
!
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
when cylinder is in use or connected for use.
8. Read and follow instructions on compressed
gas cylinders, associated equipment, and CGA
publication P-1 listed in Safety Standards.
WARNING
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut
fingers and hands and catch loose clothing.
1. Keep all doors, panels, covers, and guards closed
and securely in place.
2. Stop engine before installing or connecting unit.
3. Have only qualified people remove guards or
covers for maintenance and troubleshooting as
necessary.
4. To prevent accidental starting during servicing,
disconnect negative (-) battery cable from battery.
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.
5. Keep hands, hair, loose clothing, and tools away
from moving parts.
6. Reinstall panels or guards and close doors when
servicing is finished and before starting engine.
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.)

2.09 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.

SECTION 3:
INSTALLATION, OPERATION AND SETUP
3.01 Environment
These units are designed for use in environments
with increased hazard of electric shock as outlined in
AS60974.1 and AS1674.2
A. Examples of environments with increased hazard
of electric shock are:
1. 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.
2. 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.
3. In wet or damp hot locations where humidity
or perspiration considerable reduces the
skin resistance of the human body and the
insulation properties of accessories.
B. 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
conditions. For further information please refer
to AS 60529.
H. Precautions must be taken against the power
source toppling over. The power source must
be located on a suitable horizontal surface in the
upright position when in use.
3.03 Ventilation
Since the inhalation of welding fumes can be harmful,
ensure that the welding area is effectively ventilated.
3.04 Mains Supply Voltage Requirements
The Mains supply voltage should be within ± 15%
of the rated mains supply voltage. Too low a voltage
may cause poor welding performance. Too high a
supply voltage will cause components to overheat
and possibly fail.
The Welding Power Source must be:
• Correctlyinstalled,ifnecessary,byaqualied
electrician.
• Correctlyearthed (electrically) in accordance
with local regulations.
• Connectedtothecorrectsizepowerpointand
fuse as per the Specifications on page 2-5.
Be sure to locate the welder according to the following
guidelines:
A. In areas, free from moisture and dust.
B. Ambient temperature between 0° C to 40° C.
C. In areas, free from oil, steam and corrosive
gases.
D. In areas, not subjected to abnormal vibration or
shock.
E. In areas, not exposed to direct sunlight or rain.
F. Place at a distance of 300mm or more from walls
or similar that could restrict natural air flow for
cooling.
G. The enclosure design of this power source meets
the requirements of IP23S as outlined in AS60529.
This provides adequate protection against solid
objects (greater than 12mm), and direct protection
from vertical drops. Under no circumstances
should the unit be operated or connected in a
micro environment that will exceed the stated
!
WARNING
Any electrical work must be carried out by
a qualified Electrical Tradesperson.
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
stabilised 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 firing

WARNING COMPUTER
It is also possible that operation close
to computer installations may cause
computer malfunction.
3.06 High Frequency Interference
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.
Interference may be transmitted by a high frequency
initiated or stabilised 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
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 reradiation from unearthed metallic objects close to the
welding leads. Effective grounding of such objects will
prevent re-radiation in most cases.
NOTE
The welding circuit may or may not be
earthed for safety reasons. Changing the
earthing arrangements should only be
authorised 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 60974-13 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
1. Other supply cables, control cables, signalling
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.
3.07 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
INSTALLATION, OPERATION AND SETUP 3-2 Manual 0-5207
5. The health of people around, e.g. the use of
pacemakers 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.

C. Methods of Reducing Electromagnetic Emissions
1. Mains Supply
Welding equipment should be connected to the mains supply according to the manufacturer’s
recommendations. If interference occurs, it may be necessary to take additional precautions such as
filtering of the mains 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. In particular, the spark gaps of
arc striking and stabilising devices should be adjusted and maintained according to the manufacturer’s
recommendations.
3. Welding Cables
The welding cables should be kept as short as possible and should be positioned close together, 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 of the Workpiece
Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of it’s
size and position, e.g. ship’s hull or building steelwork, a connection bonding the workpiece to earth
may reduce emissions in some, but not all instances. Care should be taken to prevent the earthing of
the workpiece increasing the risk of injury to users, or damage to other electrical equipment. Where
necessary, the connection of the workpiece to earth should be made by direct connection to the
workpiece, 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.
