see "Technical data"
In this case, the plant operator or the person using the device should check whether the
device may be connected, where appropriate by discussing the matter with the power supply company.
IMPORTANT! Ensure that the mains connection is earthed properly
EN
Protecting yourself 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 using 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 protective 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
Danger from toxic
gases and vapours
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 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
- Alternatively, erect suitable safety screens/curtains.
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.
Keep your face away from welding fumes and gases.
11
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 Association website under
Health & Safety (https://european-welding.org).
Danger from flying sparks
Flammable vapours (e.g. solvent fumes) should be kept away from the arc's radiation area.
Close the shielding gas cylinder valve or main gas supply if no welding is taking place.
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 al-
ternatively 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 accordance 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.
Risks from mains
current and welding current
12
An electric shock is potentially life threatening and can be fatal.
Do not touch live parts either inside or outside the device.
During MIG/MAG welding and TIG welding, the welding wire, the wirespool, the feed rollers
and all pieces of metal that are in contact with the welding wire are live.
Always set the wirefeeder up on a sufficiently insulated surface or use a suitable, insulated
wirefeeder holder.
Make sure that you and others are protected with an adequately insulated, dry base or cover for the earth or ground potential. This base 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. Replace loose connections and scorched, damaged, or inadequately dimensioned
cables and leads immediately.
Use the handle to ensure the power connections are tight before every use.
In the case of power cables with a bayonet connector, rotate the power cable around the
longitudinal axis by at least 180° and pretension.
Do not wrap 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 touch the electrode 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.
Arrange for the mains cable to be checked regularly by a qualified electrician to ensure the
ground conductor is functioning properly.
Protection class I devices require a mains supply with ground conductor and a connector
system with ground conductor contact for proper operation.
EN
Meandering welding currents
Operation of the device on a mains supply without ground conductor and on a socket without ground conductor contact is only permitted if all national regulations for protective separation are observed.
Otherwise, this is considered gross negligence. The manufacturer shall not be held liable
for any damage arising from such usage.
If necessary, provide adequate earthing for the workpiece.
Switch off unused devices.
Wear a safety harness if working at height.
Before working on the device, switch it off and pull out the mains plug.
Attach a clearly legible and easy-to-understand warning sign to the device to prevent any-
one from plugging the mains plug back in and switching it on again.
After opening the device:
- Discharge all live components
- Ensure that all components in the device are de-energised.
If work on live parts is required, appoint a second person to switch off the main switch at
the right moment.
If the following instructions are ignored, meandering welding currents can develop 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.
13
Position the device with sufficient insulation against electrically conductive environments,
e.g. Insulation against conductive floor or insulation to conductive racks.
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 sufficiently insulated.
In the case of automated MIG/MAG applications, ensure that only an insulated wire electrode is routed from the welding wire drum, large wirefeeder spool or wirespool to the wirefeeder.
EMC Device Classifications
EMC measures In certain cases, even though a device complies with the standard limit values for emis-
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 supplied from the public low-voltage mains.
EMC device classification as per the rating plate or technical data.
sions, 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 rectify 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 connection, addition-
al measures are necessary (e.g. use a suitable line filter).
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
14
EMF measures 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 approaching 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
Specific hazards Keep hands, hair, clothing and tools away from moving parts. For example:
- Fans
- Cogs
- Rollers
- Shafts
- Wirespools and welding wires
Do not reach into the rotating cogs of the wire drive or into rotating drive components.
Covers and side panels may only be opened/removed while maintenance or repair work is
being carried out.
During operation
- Ensure that all covers are closed and all side panels are fitted properly.
- Keep all covers and side panels closed.
EN
The welding wire emerging from the welding torch poses a high risk of injury (piercing of
the hand, injuries to the face and eyes, etc.).
Therefore always keep the welding torch away from the body (devices with wire-feed unit)
and wear suitable protective goggles.
Never touch the workpiece during or after welding - risk of burns.
Slag can jump off cooling workpieces. The specified protective equipment must therefore
also be worn when reworking workpieces, and steps must be taken to ensure that other
people are also adequately protected.
Welding torches and other parts with a high operating temperature must be allowed to cool
down before handling.
Special provisions apply in areas at risk of fire or explosion - observe relevant
national and international regulations.
Power sources for work in areas with increased electric risk (e.g. near boilers) must carry
the "Safety" sign. However, the power source must not be located in such areas.
Risk of scalding from escaping coolant. Switch off cooling unit before disconnecting coolant flow or return lines.
Observe the information on the coolant safety data sheet when handling coolant. The coolant safety data sheet may be obtained from your service centre or downloaded from the
manufacturer's website.
Use only suitable load-carrying equipment supplied by the manufacturer when transporting
devices by crane.
- Hook chains and/or ropes onto all suspension points provided on the load-carrying
equipment.
- Chains and ropes must be at the smallest angle possible to the vertical.
- Remove gas cylinder and wire-feed unit (MIG/MAG and TIG devices).
15
If the wire-feed unit is attached to a crane holder during welding, always use a suitable,
insulated wirefeeder hoisting attachment (MIG/MAG and TIG devices).
If the device has a carrying strap or handle, this is intended solely for carrying by hand. The
carrying strap is not to be used if transporting with a crane, counterbalanced lift truck or
other mechanical hoist.
All lifting accessories (straps, handles, chains, etc.) used in connection with the device or
its components must be tested regularly (e.g. for mechanical damage, corrosion or changes caused by other environmental factors).
The testing interval and scope of testing must comply with applicable national standards
and directives as a minimum.
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 Teflon tape.
Factors affecting
welding results
Danger from
shielding gas cylinders
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.
IMPORTANT! There is an increased risk of soiling if ring mains are being used
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.
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.
16
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 inter-
national regulations for shielding gas cylinders and accessories.
Danger from escaping shielding
gas
Risk of suffocation from the uncontrolled escape of shielding gas
EN
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 taking place.
- Check the shielding gas cylinder or main gas supply for uncontrolled gas leakage before every start-up.
Safety measures
at the installation
location and during transport
A device toppling over could easily kill someone. Place the device on a solid, level surface
such that it remains stable
- The maximum permissible tilt angle is 10°.
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 protection 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 guidelines and accident prevention regulations. This applies especially to guidelines regarding the risks arising during transport.
Do not lift or transport operational devices. Switch off devices before transport or lifting.
Before transporting the device, allow coolant to drain completely and detach the following
components:
- Wirefeeder
- Wirespool
- Shielding gas cylinder
Safety measures
in normal operation
After transporting the device, the device must be visually inspected for damage before
commissioning. Any damage must be repaired by trained service technicians before commissioning the device.
Only operate the device when all safety devices are fully functional. If the safety devices
are not fully functional, there is a risk of
- injury or death to the operator or a third party
- damage to the device and other material assets belonging to the operator
- inefficient operation of the device
Any safety devices that are not functioning properly must be repaired before switching on
the device.
Never bypass or disable safety devices.
Before switching on the device, ensure that no one is likely to be endangered.
Check the device at least once a week for obvious damage and proper functioning of safety
devices.
17
Always fasten the shielding gas cylinder securely and remove it beforehand if the device
is to be transported by crane.
Only the manufacturer's original coolant is suitable for use with our devices due to its properties (electrical conductibility, anti-freeze agent, material compatibility, flammability, etc.).
Only use suitable original coolant from the manufacturer.
Do not mix the manufacturer's original coolant with other coolants.
Only connect the manufacturer's system components to the cooling circuit.
The manufacturer accepts no liability for damage resulting from use of other system com-
ponents or a different coolant. In addition, all warranty claims will be forfeited.
Cooling Liquid FCL 10/20 does not ignite. The ethanol-based coolant can ignite under cer-
tain conditions. Transport the coolant only in its original, sealed containers and keep well
away from any sources of ignition.
Used coolant must be disposed of properly in accordance with the relevant national and
international regulations. The coolant safety data sheet may be obtained from your service
centre or downloaded from the manufacturer's website.
Check the coolant level before starting to weld, while the system is still cool.
Commissioning,
maintenance and
repair
Safety inspection The manufacturer recommends that a safety inspection of the device is performed at least
It is impossible to guarantee that bought-in parts are designed and manufactured to meet
the demands made of them, or that they satisfy safety requirements.
- Use only original spare and wearing parts (also applies to standard parts).
- Do not carry out any modifications, alterations, etc. to the device without the manufacturer's consent.
- Components that are not in perfect condition must be replaced immediately.

TIG pulsing The welding current set at the start of welding is not always ideal for the welding process
If the arc breaks and no current starts to flow again within a time specified in the Setup
menu, the power source cuts out automatically. The service code "no | Arc" appears on the
control panel.
To start the welding process again, press any key on the control panel or the torch trigger.
The settings for the arc break watchdog setup parameter are described in the "Setup
menu: level 2" section.
The power source has the Ignition time-out function.
Once the torch trigger is pressed, gas pre-flow begins immediately. Ignition then begins. If
no arc appears within the time specified in the Setup menu, the power source cuts out automatically. The service code "no | IGn" appears on the control panel.
To try again, press any key on the control panel or press the torch trigger.
The settings for the Ignition time-out parameter (ito) are described in the "Setup menu: level 2" section.
as a whole:
- if the current is too low, the base material will not melt sufficiently,
- if overheating occurs, the liquid weld pool may drip.
The TIG pulsing function (TIG welding with pulsing welding current) offers a remedy:
a low ground current I-G rises steeply to the significantly higher pulse current I1 and, depending on the set dcY (duty cycle) time, drops back to the ground current I-G.
In TIG pulsing, small sections of the welding location melt quickly and then solidify again
quickly.
In manual applications using TIG pulsing, the filler wire is applied in the maximum current
phase (only possible in the low frequency range: 0.25 - 5 Hz). Higher pulse frequencies are
mainly used in automatic mode to stabilise the arc.
TIG pulsing is used for out-of-position welding of steel pipes or when welding thin sheets.

Depending on what tAC time has been set, the pulsed welding current may continue up to
and including the end current phase IE (tAC setup parameter set to "ON").
After the tAC time has elapsed, welding continues at a constant welding current, and any
pulsing parameters that may have been set continue to be available.
IMPORTANT! To set a specified tacking time, the tAC setup parameter can be combined
with the SPt setup parameter (spot welding time).

Anti-stick function
As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will
tend to stick. This may also cause the rod electrode to burn out.
Electrode burn-out is prevented by activating the anti-stick function. If the rod electrode begins to stick, the power source immediately switches the welding current off. After the rod
electrode has been detached from the workpiece, the welding process can be continued
without any problems.
The anti-stick function can be activated and deactivated in the "Setup menu: level 2" section.

Risk of injury due to shock caused by electric shock
Although Fronius devices comply with all relevant standards, high-frequency ignition can
transmit a harmless but noticeable electric shock under certain circumstances.
► Use prescribed protective clothing, especially gloves!
► Only use suitable, completely intact and undamaged TIG hosepacks!
► Do not work in damp or wet environments!
► Take special care when working on scaffolding, work platforms, in forced positions
(out-of-position welding), in tight, difficult to access or exposed areas!
The special HF ignition indicator remains lit as long as a value has been specified for the
HFt parameter.
If the HFt setup parameter is set to "OFF", no high-frequency ignition takes place at the

To obtain optimum welding results, it will sometimes be necessary to adjust the arc-force
dynamic.
Functional principle:
at the instant of droplet transfer or when a short circuit occurs, there is a momentary rise
in amperage. In order to obtain a stable arc, the welding current is temporarily increased.
If the rod electrode threatens to sink into the weld pool, this measure prevents the weld
pool solidifying, as well as preventing more prolonged short circuiting of the arc. This
largely prevents the rod electrode from sticking.

As the arc becomes shorter, the welding voltage may drop so far that the rod electrode
will tend to stick. This may also cause the rod electrode to burn out.
Electrode burn-out is prevented by activating the anti-stick function. If the rod electrode
begins to stick, the power source immediately switches the welding current off. After the
rod electrode has been detached from the workpiece, the welding process can be continued without any problems.

The arc length depends on the welding voltage. To end the welding process, it is usually
necessary to significantly lift the rod electrode away from the workpiece. With the "Uco"
parameter, the welding voltage can be limited to a value that makes it possible to end the
welding process simply by lifting the rod electrode slightly.
IMPORTANT! If the welding process often ends unintentionally during welding, set the
Uco parameter to a higher value.
