EN
Obligations of
personnel
Protecting your-
self and others
Before using the device, all persons instructed to do so undertake:
- to observe the basic instructions regarding safety at work and accident
prevention
- to read these operating instructions, especially the "Safety rules" section
and sign to confirm that they have understood them and will follow them.
Before leaving the workplace, ensure that people or property cannot come to
any harm in your absence.
Persons involved with welding expose 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
using cardiac pacemakers
- risk of electrocution from mains current and welding current
- greater noise pollution
- harmful welding fumes and gases
Anyone working on the workpiece while welding is in progress must wear suit-
able protective clothing with 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 protec-
tive 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
injury.
Keep all persons, especially children, out of the working area while any devic-
es are in operation or welding is in progress. If, however, there are people in
the vicinity,
- 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 current and welding current, etc.),
- provide suitable protective equipment or
- erect suitable safety screens/curtains.

8
Noise emission
values
Danger from toxic
gases and va-
pours
Danger from fly-
ing sparks
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
workpiece, the workplace environment, etc.
The fumes produced during welding contain harmful gases and vapours.
Welding fumes contain substances that may, under certain circumstances,
cause birth defects or cancer.
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.
Otherwise, a protective mask with an air supply must be worn.
Close the shielding gas cylinder valve or main gas supply if no welding is tak-
ing place.
If there is any doubt about whether the extraction system is powerful enough,
then the measured toxic emission values should be compared with the permis-
sible limit values.
The following components are responsible, amongst other things, for the de-
gree of toxicity of welding fumes:
- Metals used for the workpiece
- Electrodes
- Coatings
- Cleaners, degreasers, etc.
The relevant material safety data sheets and manufacturer's specifications for
the listed components should therefore be studied carefully.
Flammable vapours (e.g. solvent fumes) should be kept away from the arc's
radiation area.
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 in-
jury or fire.

EN
Dangers from
welding current
Dangers from the
battery
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 ac-
cordance 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.
An electric shock is potentially life threatening and can be fatal.
Do not touch live parts either inside or outside the device.
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
dimensioned. Loose connections, scorched, damaged or inadequately dimen-
sioned 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 elec-
trodes at the same time may be fatal under certain circumstances.
If necessary, provide an adequate earthing connection for the workpiece.
Switch off unused devices.
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
relevant national regulations
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.
If this happens:
- Ensure an adequate supply of fresh air
- Seek medical attention in case of discomfort
With a faulty battery, liquid may leak out of the device.
- Avoid contact with the liquid
- Hand the device over to a Fronius Service Partner for repair
- Clean and check any parts that have come into contact with the liquid
Do not operate or store the device in a potentially explosive atmosphere.
Special regulations apply in rooms at risk of fire or explosion.
Observe relevant national and international regulations.

Meandering weld-
ing currents
EMC Device Clas-
sifications
To comply with European Directive 2006/66/EC on Batteries and Accumula-
tors and its implementation in national law, batteries and rechargeable batter-
ies 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 require to your dealer, or find out about the approved collection and
recycling facilities in your area. Ignoring this European Directive may be harm-
ful to the environment and your own health!
Devices with mechanically undamaged rechargeable batteries may be re-
turned to the relevant Fronius Service Partner for repair or battery replace-
ment.
As soon as it becomes evident that the rechargeable battery has been me-
chanically 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.
If the following instructions are ignored, meandering welding currents can de-
velop 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 weld-
ed.
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 follow-
ing: 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 sufficiently insulated.
Devices in emission class A:
- Are only designed for use in industrial settings
- Can cause line-bound and radiated interference in other areas
Devices in emission class B:
- Satisfy the emissions criteria for residential and industrial areas.
This is also true for residential areas in which the energy is sup-
plied from the public low-voltage mains.
EMC device classification as per the rating plate or technical data.

EMF measures
Factors affecting
welding results
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 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 rec-
tify the situation.
Check and evaluate the immunity to interference of nearby devices according
to national and international regulations. Examples of equipment that may be
susceptible to interference from the device include:
- Safety devices
- Power, 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 correct mains connec-
tion, additional measures are necessary (e.g. use a suitable line fil-
ter).
2. Welding power leads
- must be kept as short as possible
- must run 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. Shielding, if necessary
- Shield off other nearby devices
- Shield off entire welding installation
Electromagnetic fields may pose as yet unknown risks to health:
- effects on the health of others in the vicinity, e.g. wearers of pacemakers
and hearing aids
- wearers of pacemakers must seek advice from their doctor before ap-
proaching the device or any welding that is in progress
- for safety reasons, keep distances between the welding cables and the
welder's head/torso as large as possible
- do not carry welding cables and hosepacks over the shoulders or wind
them around any part of the body
The following requirements with regard to shielding gas quality must be met if
the welding system is to operate in a correct and safe manner:
- Size of solid matter particles < 40 μm
- Pressure dew point < -20 °C
- Max. oil content < 25 mg/m³
Filters must be used if necessary.
NOTE! There is an increased risk of soiling if ring mains are being
used

12
Danger from
shielding gas cyl-
inders
Safety precau-
tions in the place
of use and for
storage and
transport
Shielding gas cylinders contain gas under pressure and can explode if dam-
aged. 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 instruc-
tions to prevent them falling over.
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 na-
tional and international regulations for shielding gas cylinders and accesso-
ries.
A toppling device can cause life-threatening injuries. Place the device on a sol-
id, level surface so that it remains stable
- The maximum permissible tilt angle is 10°.
Do not operate or store the device in a potentially explosive atmosphere.
Special regulations apply in rooms at risk of fire or explosion.
Observe relevant national and international regulations.
Use internal directives and checks to ensure that the workplace environment
is always clean and clearly laid out.
Only set up and operate the device in accordance with the degree of protec-
tion shown on the rating plate.
When setting up the device, ensure there is an all-round clearance of 0.5 m (1
ft. 7.69 in.) to ensure that cooling air can flow in and out freely.
When transporting the device, observe the relevant national and local guide-
lines and accident prevention regulations. This applies especially to guidelines
regarding the risks arising during transport.
After transporting the device, it must be visually inspected for damage before
commissioning. Any damage must be repaired by trained service technicians
before commissioning the device.
Odourless and colourless shielding gas may escape unnoticed if an adapter
is used for the shielding gas connection. Prior to assembly, seal the device-
side thread of the adapter for the shielding gas connection using suitable Tef-
lon tape.

Features of hybrid mode:
- QUICK CHARGING indicator
lit
- Mains indicator lit
- The battery is charged at the maximum
possible charging power
Hybrid mode starts automatically:
-if the battery starts being used while it is being charged
-if the charger is connected to the battery while the battery is being used
Hybrid mode stops:
-when the charger is disconnected from the battery
-when the battery stops being used
-in this case the previously selected operating mode (charging or quick charg-
ing) resumes
