Protecting your-
self and others
Anyone working with the device exposes themselves to numerous risks, e.g.
-flying sparks and hot pieces of metal
-Arc radiation, which can damage eyes and skin
-Hazardous electromagnetic fields, which can endanger the lives of those us-
ing cardiac pacemakers
-Risk of electrocution from mains current and welding current
-Greater noise pollution
-Harmful welding fumes and gases
Suitable protective clothing must be worn when working with the device. The
protective clothing must have the following properties:
-Flame-resistant
-Insulating and dry
-Covers the whole body, is undamaged and in good condition
-Safety helmet
-Trousers with no turn-ups
Protective clothing refers to a variety of different items. Operators should:
-Protect eyes and face from UV rays, heat and sparks using a protective visor
and regulation filter
-Wear regulation protective goggles with side protection behind the protect-
ive visor
-Wear stout footwear that provides insulation even in wet conditions
-Protect the hands with suitable gloves (electrically insulated and providing
protection against heat)
-Wear ear protection to reduce the harmful effects of noise and to prevent in-
jury
Keep all persons, especially children, out of the working area while any devices
are in operation or welding is in progress. If, however, there are people in the vi-
cinity:
-Make them aware of all the dangers (risk of dazzling by the arc, injury from
flying sparks, harmful welding fumes, noise, possible risks from mains cur-
rent and welding current, etc.)
-Provide suitable protective equipment
-Alternatively, erect suitable safety screens/curtains.
Noise emission
values
The device generates a maximum sound power level of <80 dB(A) (ref. 1pW)
when idling and in the cooling phase following operation at the maximum per-
missible operating point under maximum rated load conditions according to EN
60974-1.
It is not possible to provide a workplace-related emission value during welding
(or cutting) as this is influenced by both the process and the environment. All
manner of different welding parameters come into play, including the welding
process (MIG/MAG, TIG welding), the type of power selected (DC or AC), the
power range, the type of weld metal, the resonance characteristics of the work-
piece, the workplace environment, etc.
Danger from tox-
ic gases and va-
pours
The fumes produced during welding contain harmful gases and vapours.
Welding fumes contain substances that cause cancer, as stated in Monograph
118 of the International Agency for Research on Cancer.
Use at-source extraction and a room extraction system.
If necessary, use a welding torch with an integrated extraction device.
12

Keep your face away from welding fumes and gases.
Fumes and hazardous gases
-must not be breathed in
-must be extracted from the working area using appropriate methods.
Ensure an adequate supply of fresh air. Ensure that there is a ventilation rate of
at least 20 m³ per hour at all times.
Otherwise, a welding helmet with an air supply must be worn.
If there is any doubt about whether the extraction capacity is sufficient, the
measured toxic emission values should be compared with the permissible limit
values.
The following components are responsible, amongst other things, for the degree
of toxicity of welding fumes:
-Metals used for the workpiece
-Electrodes
-Coatings
-Cleaners, degreasers, etc.
-Welding process used
The relevant material safety data sheets and manufacturer's specifications for
the listed components should therefore be studied carefully.
Recommendations for trade fair scenarios, risk management measures and for
identifying working conditions can be found on the European Welding Associ-
ation website under Health & Safety (https://european-welding.org).
Flammable vapours (e.g. solvent fumes) should be kept away from the arc's radi-
ation area.
Close the shielding gas cylinder valve or main gas supply if no welding is taking
place.
Danger from fly-
ing sparks
Flying sparks may cause fires or explosions.
Never weld close to flammable materials.
Flammable materials must be at least 11 metres (36 ft. 1.07 in.) away from the
arc, or alternatively covered with an approved cover.
A suitable, tested fire extinguisher must be available and ready for use.
Sparks and pieces of hot metal may also get into adjacent areas through small
gaps or openings. Take appropriate precautions to prevent any danger of injury or
fire.
Welding must not be performed in areas that are subject to fire or explosion or
near sealed tanks, vessels or pipes unless these have been prepared in accord-
ance with the relevant national and international standards.
Do not carry out welding on containers that are being or have been used to store
gases, propellants, mineral oils or similar products. Residues pose an explosive
hazard.
Dangers from
welding current An electric shock is potentially life threatening and can be fatal.
Do not touch live parts either inside or outside the device.
13
EN

Make sure that you and others are protected with an adequately insulated, dry
temporary backing or cover for the earth or ground potential. This temporary
backing or cover must extend over the entire area between the body and the
earth or ground potential.
All cables and leads must be secured, undamaged, insulated and adequately di-
mensioned. Loose connections, scorched, damaged or inadequately dimensioned
cables and leads must be replaced immediately.
Do not sling cables or leads around the body or parts of the body.
The electrode (rod electrode, tungsten electrode, welding wire, etc.) must
-never be immersed in liquid for cooling
-never be touched when the power source is switched on.
Double the open circuit voltage of a power source can occur between the welding
electrodes of two power sources. Touching the potentials of both electrodes at
the same time may be fatal under certain circumstances.
If necessary, provide an adequate earthing connection for the workpiece.
Switch off unused devices.
Dangers from
the battery The substances contained in the battery used in this device can be harmful to
the environment and to human and animal health.
If the device becomes damaged, please observe the following points:
-Make sure that leaking fluids cannot get into the soil or groundwater
-If pollution has already occurred, it must be removed in accordance with rel-
evant national regulations
Liquid may leak from the battery if used or stored under improper conditions.
-The liquid may cause irritation or burns.
-Avoid contact with this liquid.
-In case of accidental contact, clean the affected area immediately with wa-
ter.
-In case of eye contact, also consult a doctor.
The battery can catch fire if overheated. Do not expose the device to heat
(e.g. a permanent heat source or fire)
If the battery is damaged or subjected to improper use, dangerous vapours may
be given off which can irritate the airways.

To comply with European Directive 2006/66/EC on batteries and accumulators
and its implementation in national law, batteries and rechargeable batteries that
have reached the end of their life must be collected separately and returned to
an approved recycling facility. Be sure to return any device that you no longer re-
quire to your distributor, or find out about the approved collection and recycling
14

facilities in your area. Ignoring this European Directive may have potentially ad-
verse effects on the environment and your health!
Devices with mechanically undamaged rechargeable batteries may be returned to
the relevant Fronius Service Partner for repair or battery replacement.
As soon as it becomes evident that the rechargeable battery has been mechanic-
ally damaged (e.g. electrolyte is escaping), dispose of the device at your nearest
recycling centre in accordance with national laws and guidelines.
If anything is unclear or you have any questions about disposal, contact your
Fronius Service Partner.
Use only the "ActiveCharger 1000" battery charger to charge the power source.
Use of a different charger poses a fire risk.
Only operate the power source using the battery provided. Use of a different bat-
tery could result in the risk of injury and/or fire.
If the battery is disconnected, keep it away from metal objects such as paper-
clips, coins, keys, nails, screws or other small metal objects that could establish a
connection between the battery terminals. Short circuiting of the battery poles
could result in a burn injury or a fire.
Do not use damaged or modified batteries and power sources. Damaged or modi-
fied components and devices may exhibit unpredictable behaviour that could res-
ult in an explosion or injury.
Do not expose the power source and the battery to fire or temperatures exceed-
ing 130 °C (266 °F). This could result in an explosion.
Follow the charging instructions contained in these Operating Instructions. Do
not charge the battery outside of the permitted temperature range - see sec-
tionEnvironmental conditions on page 20. Improper charging or exposure to
unauthorised temperatures could damage the battery and increase the risk of
fire.
Meandering
welding currents If the following instructions are ignored, meandering welding currents can devel-
op with the following consequences:
-Fire hazard
-Overheating of parts connected to the workpiece
-Irreparable damage to ground conductors
-Damage to device and other electrical equipment
Ensure that the workpiece is held securely by the workpiece clamp.
Attach the workpiece clamp as close as possible to the area that is to be welded.
If the floor is electrically conductive, the device must be set up with sufficient
insulating material to insulate it from the floor.
If distribution boards, twin-head mounts, etc., are being used, note the following:
The electrode of the welding torch / electrode holder that is not used is also live.
Make sure that the welding torch / electrode holder that is not used is kept suffi-
ciently insulated.
EMC measures In certain cases, even though a device complies with the standard limit values for
emissions, it may affect the application area for which it was designed (e.g. when
15
EN

there is sensitive equipment at the same location, or if the site where the device
is installed is close to either radio or television receivers).
If this is the case, then the operator is obliged to take appropriate action to recti-
fy the situation.
Check and evaluate the immunity to interference of nearby devices according to
national and international regulations. Examples of equipment that may be sus-
ceptible to interference from the device include:
-Safety devices
-Network, signal and data transfer lines
-IT and telecommunications devices
-Measuring and calibrating devices
Supporting measures for avoidance of EMC problems:
1.Mains supply
-If electromagnetic interference arises despite the correct mains connec-
tion, additional measures are necessary (e.g. use of a suitable line filter)
2.Welding power-leads
-must be kept as short as possible
-must be laid close together (to avoid EMF problems)
-must be kept well apart from other leads
3.Equipotential bonding
4.Earthing of the workpiece
-If necessary, establish an earth connection using suitable capacitors.
5.Shield, if necessary
-Shield other devices nearby
-Shield the entire welding installation
EMF measures Electromagnetic fields may pose as yet unknown risks to health:
-Effects on the health of persons in the vicinity, e.g. those with pacemakers
and hearing aids
-Individuals with pacemakers must seek advice from their doctor before ap-
proaching the device or any welding that is in progress
-For safety reasons, maintain as large a distance as possible between the
welding power-leads and the head/torso of the welder
-Do not carry welding power-leads and hosepacks over the shoulders or wind
them around any part of the body
Requirement for
the shielding gas
Especially with ring lines, contaminated shielding gas can cause damage to
equipment and reduce welding quality.
Meet the following requirements regarding shielding gas quality:
-Solid particle size < 40 µm
-Pressure condensation point < -20 °C
-Max. oil content < 25 mg/m³
Use filters if necessary.
Danger from
shielding gas cyl-
inders
Shielding gas cylinders contain gas under pressure and can explode if damaged.
As the shielding gas cylinders are part of the welding equipment, they must be
handled with the greatest of care.
Protect shielding gas cylinders containing compressed gas from excessive heat,
mechanical impact, slag, naked flames, sparks and arcs.
Mount the shielding gas cylinders vertically and secure according to instructions
to prevent them falling over.
16

Keep the shielding gas cylinders well away from any welding or other electrical
circuits.
Never hang a welding torch on a shielding gas cylinder.
Never touch a shielding gas cylinder with an electrode.
Risk of explosion - never attempt to weld a pressurised shielding gas cylinder.
Only use shielding gas cylinders suitable for the application in hand, along with
the correct and appropriate accessories (regulator, hoses and fittings). Only use
shielding gas cylinders and accessories that are in good condition.
Turn your face to one side when opening the valve of a shielding gas cylinder.
Close the shielding gas cylinder valve if no welding is taking place.
If the shielding gas cylinder is not connected, leave the valve cap in place on the
cylinder.
The manufacturer's instructions must be observed as well as applicable national
and international regulations for shielding gas cylinders and accessories.
Danger from es-
caping shielding
gas
Risk of suffocation from the uncontrolled escape of shielding gas
Shielding gas is colourless and odourless and, in the event of a leak, can displace
the oxygen in the ambient air.
-Ensure an adequate supply of fresh air with a ventilation rate of at least
20 m³/hour.
-Observe safety and maintenance instructions on the shielding gas cylinder or
the main gas supply.
-Close the shielding gas cylinder valve or main gas supply if no welding is tak-
ing place.
-Check the shielding gas cylinder or main gas supply for uncontrolled gas
leakage before every start-up.
Safety precau-
tions in the place
of use and for
storage and
transport
