Before leaving the workplace, ensure that people or property cannot come to any
harm in your absence.
Mains connec-
tion
Devices with a higher rating may affect the energy quality of the mains due to
their current consumption.
This may affect a number device types in terms of:
-Connection restrictions
-Criteria with regard to the maximum permissible mains impedance *)
-Criteria with regard to the minimum short-circuit power requirement *)
*) at the interface with the public grid
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 mat-
ter with the power supply company.
IMPORTANT! Ensure that the mains connection is earthed properly
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.

EN

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.
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.
10

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
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 di-
mensioned. 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.
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 regula-
tions 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 anyone 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.
11
EN

If work on live parts is required, appoint a second person to switch off the main
switch at the right moment.
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
-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.
Position the device with sufficient insulation against electrically conductive envir-
onments, such as insulation against conductive floor or insulation to conductive
racks.
If power distribution boards, twin-head mounts, etc., are being used, note the fol-
lowing: 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
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.
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
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)
12

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
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 com-
ponents.
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.
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
wirefeeder) 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 al-
lowed 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.
13
EN

Risk of scalding from escaping coolant. Switch off cooling unit before discon-
necting 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 down-
loaded from the manufacturer's website.
Use only suitable load-carrying equipment supplied by the manufacturer when
transporting devices by crane.
-Hook chains or ropes onto all suspension points provided on the load-carry-
ing equipment.
-Chains and ropes must be at the smallest angle possible to the vertical.
-Remove gas cylinder and wirefeeder (MIG/MAG and TIG devices).
If the wirefeeder is attached to a crane holder during welding, always use a suit-
able, 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, counter-
balanced lift truck or other mechanical hoist.
All lifting tackle (straps, handles, chains, etc.) used in connection with the device
or its components must be tested regularly (e.g. for mechanical damage, corro-
sion 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.
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.
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.
14

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 measures
at the installa-
tion 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 regard-
ing 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
After transporting the device, the device must be visually inspected for damage
before commissioning. Any damage must be repaired by trained service techni-
cians before commissioning the device.

Check the device at least once a week for obvious damage and proper function-
ing of safety devices.
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 compatibil-
ity, 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 sys-
tem components 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 certain conditions. Transport the coolant only in its original, sealed con-
tainers and keep well away from any sources of ignition.
Used coolant must be disposed of properly in accordance with the relevant na-
tional and international regulations. The coolant safety data sheet may be ob-
tained 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

cified torque.
16

Safety inspec-
tion
The manufacturer recommends that a safety inspection of the device is per-
formed at least once every 12 months.
The manufacturer recommends that the power source be calibrated during the
same 12-month period.
A safety inspection should be carried out by a qualified electrician
-after any changes are made
-after any additional parts are installed, or after any conversions
-after repair, care and maintenance has been carried out
-at least every twelve months.
For safety inspections, follow the appropriate national and international stand-
ards and directives.
Further details on safety inspection and calibration can be obtained from your
service centre. They will provide you on request with any documents you may re-
quire.
Disposal Waste electrical and electronic equipment must be collected separately and re-
cycled in an environmentally-friendly way, in accordance with the European Dir-
ective and national legislation. Used equipment must be returned to the distrib-
utor or disposed of via an approved local collection and disposal facility. Correct
disposal of used equipment promotes the sustainable recycling of material re-
sources. Failing to dispose of used equipment correctly can lead to adverse
health and/or environmental impacts.
Packaging materials
