1.2 Safety precautions
!!
WARNING!
These Safety Precautions are for your protection. They summarize precautionary information
from the references listed in Additional Safety Information section.
Before performing any installation or operating procedures, be sure to read and follow the
safety precautions listed below as well as all other manuals, material safety data sheets, labels,
etc. Failure to observe Safety Precautions can result in injury or death.
PROTECT YOURSELF AND OTHERS
Some welding, cutting and gouging processes are noisy and require ear protection. The arc, like the
sun, emits ultraviolet (UV) and other radiation and can injure skin and eyes. Hot metal can cause
burns. Training in the proper use of the processes and equipment is essential to prevent accidents.
Therefore:
1. Wear a welding helmet tted with a proper shade of lter to protect you face and eyes when welding or watching.
2. Always wear safety glasses with side shields in any work area, even if welding helmets face shields and goggles are
also required.
3. Use a face shield tted with the correct lter and cover plates to protect your eyes, face, neck and ears from sparks
and rays of the arc when operating or observing operations. Warn bystanders not to watch the arc and not to expose
themselves to the rays of the electric-arc or hot metal.
4. Wear ameproof gauntlet type gloves, heavy long-sleeve shirt, cu less trousers, high-topped shoes and a welding
helmet or cap for protection, to protect against arc rays and hot sparks or hot metal. A ameproof apron may also
be desirable as protection against radiated heat and sparks.
5. Hot sparks or metal can lodge in rolled up sleeves, trouser cus, or pockets. Sleeves and collars should be kept
buttoned and open pockets eliminated from the front of clothing.
1 SAFETY
0463 703 001

6. Protect other personnel from arc rays and hot sparks with a suitable non-ammable partition or curtains.
7. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be hot and can y for long
distances. Bystanders should also wear goggles over safety glasses.
FIRES AND EXPLOSIONS
Heat from ames and arcs can start res. Hot slag or sparks can also cause res and explosions.
Therefore:
1. Protect yourself and others from ying sparks and hot metal.
2. Remove all combustible materials well away from the work area or cover the materials with a protective non-
ammable covering. Combustible materials include wood, cloth, sawdust, liquid and gas fuels, solvents, paints and
coatings paper, etc.
3. Hot sparks or hot metal can fall through cracks or crevices in oors or wall openings and cause a hidden smoldering
re or res on the oor below. Make certain that such openings are protected from hot sparks and metal.
4. Do not weld, cut or perform other hot work until the work piece has been completely cleaned so that there are
no substances on the work piece which might produce ammable or toxic vapors. Do not do hot work on closed
containers. They may explode.
5. Have re extinguishing equipment handy for instant use, such as a garden hose, water pail, sand bucket, or portable
re extinguisher. Be sure you are trained in its use.
6. Do not use equipment beyond its ratings. For example, overloaded welding cable can overheat and create a re
hazard.
7. After completing operations, inspect the work area to make certain there are no hot sparks or hot metal which
could cause a later re. Use re watchers when necessary.
ELECTRICAL SHOCK
Contact with live electrical parts and ground can cause severe injury or death. DO NOT use AC
welding current in damp areas, if movement is conned, or if there is danger of falling. Therefore:
1. Be sure the power source frame (chassis) is connected to the ground system of the input power.
2. Connect the workpiece to a good electrical ground.
3. Connect the work cable to the workpiece. A poor or missing connection can expose you or others to a fatal shock.
4. Use well-maintained equipment. Replace worn or damaged cables.
5. Keep everything dry, including clothing, work area, cables, torch/electrode holder and power source.
6. Make sure that all parts of your body are insulated from work and from ground.
7. Do not stand directly on metal or the earth while working in tight quarters or a damp area; stand on dry boards or
an insulating platform and wear rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the power.
9. Turn OFF the power before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 for specic grounding recommendations. Do not mistake the work lead for a
ground cable.
ELECTRIC AND MAGNETIC FIELDS
May be dangerous. Electric current owing through any conductor causes localized Electric and
Magnetic Fields (EMF). Welding and cutting current creates EMF around welding cables and weld-
ing machines. Therefore:
1. Welders having pacemakers should consult their physician before welding. EMF may interfere with some
pacemakers.
2. Exposure to EMF may have other health eects which are unknown.
3. Welders should use the following procedures to minimize exposure to EMF:
a) Route the electrode and work cables together. Secure them with tape when possible.
b) Never coil the torch or work cable around your body.
c) Do not place your body between the torch and work cables. Route cables on the same side of your body.
d) Connect the work cable to the workpiece as close as possible to the area being welded.
e) Keep welding power source and cables as far away from your body as possible.

FUMES AND GASES
Fumes and gases, can cause discomfort or harm, particularly in conned spaces. Shielding gases
can cause asphyxiation. Therefore:
1. Keep your head out of the fumes. Do not breathe the fumes and gases.
2. Always provide adequate ventilation in the work area by natural or mechanical means. Do not weld, cut or gouge
on materials such as galvanized steel, stainless steel, copper, zinc, lead beryllium or cadmium unless positive me-
chanical ventilation is provided. Do not breathe fumes from these materials.
3. Do not operate near degreasing and spraying operations. The heat or arc can react with chlorinated hydrocarbon
vapors to form phosgene, a highly toxic gas and other irritant gases.
4. If you develop momentary eye, nose or throat irritation while operating, this is an indication that ventilation is not
adequate. Stop work and take necessary steps to improve ventilation in the work area. Do not continue to operate
if physical discomfort persists.
5. Refer to ANSI/ASC Standard Z49.1 for specic ventilation recommendations.
6. WARNING: This product when used for welding or cutting, produces fumes or gases which contain chemicals
known to the State of California to cause birth defects and in some cases cancer (California Health & Safety Code
§25249.5 et seq.)
CYLINDER HANDLING
Cylinders, if mishandled, can rupture and violently release gas. Sudden rupture of cylinder valve
or relief device can injure or kill. Therefore:
1. Locate cylinders away from heat, sparks and ames. Never strike an arc on a cylinder.
2. Use the proper gas for the process and use the proper pressure reducing regulator designed to operate from the
compressed gas cylinder. Do not use adaptors. Maintain hoses and ttings in good condition. Follow manufacturer's
operating instructions for mounting regulator to a compressed gas cylinder.
3. Always secure cylinders in an upright position by chain or strap to suitable hand trucks, undercarriages, benches,
wall, post or racks. Never secure cylinders to work tables or xtures where they may become part of an electrical
circuit.
4. When not in use, keep cylinder valves closed. Have valve protection cap in place if regulator is not connected. Secure
and move cylinders by using suitable hand trucks.
MOVING PARTS
Moving parts, such as fans, rotors and belts can cause injury. Therefore:
1. Keep all doors, panels and covers closed and securely in place.
2. Stop engine before installing or connecting unit.
3. Have only qualied people remove covers for maintenance and troubleshooting as necessary
4. To prevent accidental starting of equipment during service, disconnect negative (-) battery cable from battery.
5. Keep hands, hair, loose clothing and tools away from moving parts.
6. Reinstall panels or covers and close doors when service is nished and before starting engine.

WARNING!
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. For example: by allowing parallel welding current
return paths which may damage the earth circuits of other equipment or cause injury/death
to individuals.

4 INSTALLATION
The installation must be carried out by a professional.
CAUTION!
This product is intended for industrial use. In a domestic environment, this product may cause
radio interference. It is the user's responsibility to take adequate precautions.
4.1 User’s responsibility
The user is responsible for installing and using the welding equipment according to the manufacturers 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. This remedial action may be as simple as earthing
the welding circuit. In other cases, it could involve constructing an electromagnetic screen enclosing the welding power
source and the work, complete with associated input lters. In all cases, electromagnetic disturbances shall be reduced to
the point where they are no longer troublesome.
4.2 Lifting instructions
The power source can be lifted using any of the handles.
!!
WARNING!
Secure the equipment - particularly if the
ground is uneven or sloping.

4.3 Location
Position the power source so that its cooling air inlets and outlets are not obstructed.
4.3.1 Assessment of area
Before installing welding equipment, the user/installer shall assess potential electromagnetic problems in the surrounding
area. The following shall be considered:
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 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.
9. 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.
Interference may be transmitted by a high frequency initiated or stabilized arc welding power source in the following ways:
Direct radiation: Radiation from the equipment 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.
Transmission via the supply lead: Without adequate shielding and ltering, 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 conduc-
tion. Adequate shielding and ltering is provided in the power source.
Radiation from welding leads: Radiated interference from welding leads, although pronounced near the leads, di-
minishes rapidly with distance. Keeping leads as short as possible will minimize this type of interference. Looping and
suspending of leads should be avoided wherever possible.
Re-radiation from unearthed metallic objects: A major factor contributing to interference is re-radiation from un-
earthed metallic objects close to the welding leads. Eective grounding of such objects will prevent re-radiation in most
cases.

4.4 High frequency interference
!!
WARNING!
The high frequency section of this machine has an output like a radio transmitter.
The power source should NOT be used near blasting operations due to the danger of
premature ring.
!
!
WARNING!
Operation close to computer installations may cause computer malfunction.
!
!
WARNING!
HIGH FREQUENCY FIELDS CAN BE DANGEROUS TO HEALTH. Extra precautions may be
required when this welding power source is used in a domestic situation. Welders with
medical pacemakers should consult their doctor before welding. EMF may interfere with
some pacemakers.
!
!
WARNING!
Equipotential bonding:
Bonding of all metallic components in the welding installation and adjacent to it might
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.
!!
WARNING!
Earthing/grounding of the work place:
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. 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.
!
!
WARNING!
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. A duly authorized person such as a properly
licensed electrician should perform the installation to avoid injury, death, or any equipment
damage.

4.5 Main supply
NOTE!
Mains supply requirements
This equipment complies with IEC 61000-3-12 provided that the short-circuit power is
greater than or equal to S
scmin
at the interface point between the user's supply and the
public system. It is the responsibility of the installer or user of the equipment to ensure,
by consultation with the distribution network operator if necessary, that the equipment
is connected only to a supply with a short-circuit power greater than or equal to S
scmin
.
Refer to the technical data in the TECHNICAL DATA chapter.
The supply voltage should be 230 V AC ±10% or 120 V AC ±10%. Too low supply voltage may cause poor welding perfor-
mance. Too high supply voltage will cause components to overheat and possibly fail. Contact the local electric utility for
information about the type of electrical service available, how proper connections should be made, and inspection required.
The welding power source must be:
Correctly installed, if necessary, by a qualied electrician.
Correctly earthed (electrically) in accordance with local regulations.
Connected to the correct size power point and fuse as tables below.
NOTE!
Use the welding power source in accordance with the relevant national regulations.
CAUTION!
Disconnect input power and secure employing "Lock-out/Tagging" procedures. Ensure
input power line disconnect switch is locked (Lock-out/Tagging) in the "Open" position
BEFORE removing input power fuses. Connecting/disconnecting should be carried out
by competent persons.
