2.3 Safety instructions
WARNING
Risk of accidents due to non-compliance with the safety instructions!
Non-compliance with the safety instructions can be fatal!
• Carefully read the safety instructions in this manual!
• Observe the accident prevention regulations and any regional regulations!
• Inform persons in the working area that they must comply with the regulations!
Risk of injury from electrical voltage!
Voltages can cause potentially fatal electric shocks and burns on contact. Even low vol-
tages can cause a shock and lead to accidents.
• Never touch live components such as welding current sockets or stick, tungsten or wire
electrodes!
• Always place torches and electrode holders on an insulated surface!
• Wear the full personal protective equipment (depending on the application)!
• The machine may only be opened by qualified personnel!
• The device must not be used to defrost pipes!
Hazard when interconnecting multiple power sources!
If a number of power sources are to be connected in parallel or in series, only a techni-
cal specialist may interconnect the sources as per standard IEC 60974-9:2010: Installa-
tion and use and German Accident Prevention Regulation BVG D1 (formerly VBG 15) or
country-specific regulations.
Before commencing arc welding, a test must verify that the equipment cannot exceed
the maximum permitted open circuit voltage.
• Only qualified personnel may connect the machine.
• When taking individual power sources out of operation, all mains and welding current leads
must be safely disconnected from the welding system as a whole. (Hazard due to reverse
polarity voltage!)
• Do not interconnect welding machines with pole reversing switch (PWS series) or machines
for AC welding since a minor error in operation can cause the welding voltages to be com-
bined, which is not permitted.
Risk of injury due to radiation or heat!
Arc radiation can lead to skin and eye injuries.
Contact with hot workpieces and sparks can lead to burns.
• Use hand shield or welding helmet with the appropriate safety level (depends on the appli-
cation).
• Wear dry protective clothing (e.g. hand shield, gloves, etc.) in accordance with
the applicable regulations of your country.
• Persons who are not directly involved should be protected with a welding curtain or suitable
safety screen against radiation and the risk of blinding!

WARNING
Risk of injury due to improper clothing!
During arc welding, radiation, heat and voltage are sources of risk that cannot be
avoided. The user has to be equipped with the complete personal protective equipment
at all times. The protective equipment has to include:
• Respiratory protection against hazardous substances and mixtures (fumes and vapours);
otherwise implement suitable measures such as extraction facilities.
• Welding helmet with proper protection against ionizing radiation (IR and UV radiation) and
heat.
• Dry welding clothing (shoes, gloves and body protection) to protect against warm environ-
ments with conditions comparable to ambient temperatures of 100 °C or higher and arcing
and work on live components.
• Hearing protection against harming noise.
Explosion risk!
Apparently harmless substances in closed containers may generate excessive pressure
when heated.
• Move containers with inflammable or explosive liquids away from the working area!
• Never heat explosive liquids, dusts or gases by welding or cutting!
Fire hazard!
Due to the high temperatures, sparks, glowing parts and hot slag that occur during
welding, there is a risk of flames.
• Be watchful of potential sources of fire in the working area!
• Do not carry any easily inflammable objects, e.g. matches or lighters.
• Ensure suitable fire extinguishers are available in the working area!
• Thoroughly remove any residue of flammable materials from the workpiece prior to starting
to weld.
• Only further process workpieces after they have cooled down. Do not allow them to contact
any flammable materials!

07.05.2021
CAUTION
Smoke and gases!
Smoke and gases can lead to breathing difficulties and poisoning. In addition, solvent
vapour (chlorinated hydrocarbon) may be converted into poisonous phosgene due to
the ultraviolet radiation of the arc!
• Ensure that there is sufficient fresh air!
• Keep solvent vapour away from the arc beam field!
• Wear suitable breathing apparatus if appropriate!
Noise exposure!
Noise exceeding 70 dBA can cause permanent hearing damage!
• Wear suitable ear protection!
• Persons located within the working area must wear suitable ear protection!
According to IEC 60974-10, welding machines are divided into two classes of
electromagnetic compatibility (the EMC class can be found in the Technical data):
Class A machines are not intended for use in residential areas where the power supply comes
from the low-voltage public mains network. When ensuring the electromagnetic compatibility of
class A machines, difficulties can arise in these areas due to interference not only in the supply
lines but also in the form of radiated interference.
Class B machines fulfil the EMC requirements in industrial as well as residential areas, inclu-
ding residential areas connected to the low-voltage public mains network.
Setting up and operating
When operating arc welding systems, in some cases, electro-magnetic interference can occur
although all of the welding machines comply with the emission limits specified in the standard.
The user is responsible for any interference caused by welding.
In order to evaluate any possible problems with electromagnetic compatibility in the
surrounding area, the user must consider the following: (see also EN 60974-10 Appendix A)
• Mains, control, signal and telecommunication lines
• Radios and televisions
• Computers and other control systems
• Safety equipment
• The health of neighbouring persons, especially if they have a pacemaker or wear a hearing
aid
• Calibration and measuring equipment
• The immunity to interference of other equipment in the surrounding area
• The time of day at which the welding work must be carried out
Recommendations for reducing interference emission
• Mains connection, e.g. additional mains filter or shielding with a metal tube
• Maintenance of the arc welding system
• Welding leads should be as short as possible and run closely together along the ground
• Potential equalization
• Earthing of the workpiece. In cases where it is not possible to earth the workpiece directly,
it should be connected by means of suitable capacitors.
• Shielding from other equipment in the surrounding area or the entire welding system
Electromagnetic fields!
The power source may cause electrical or electromagnetic fields to be produced which
could affect the correct functioning of electronic equipment such as IT or CNC devices,
telecommunication lines, power cables, signal lines and pacemakers.
• Observe the maintenance instructions!
• Unwind welding leads completely!
• Shield devices or equipment sensitive to radiation accordingly!
• The correct functioning of pacemakers may be affected (obtain advice from a doctor if nec-
essary).

CAUTION
Obligations of the operator!
The respective national directives and laws must be complied with when operating the
machine!
• Implementation of national legislation relating to framework directive 89/391/EEC on the int-
roduction of measures to encourage improvements in the safety and health of workers at
work and associated individual guidelines.
• In particular, directive 89/655/EEC concerning the minimum safety and health requirements
for the use of work equipment by workers at work.
• The regulations applicable to occupational safety and accident prevention in the country
concerned.
• Setting up and operating the machine as per IEC 60974.-9.
• Brief the user on safety-conscious work practices on a regular basis.
• Regularly inspect the machine as per IEC 60974.-4.
The manufacturer's warranty becomes void if non-genuine parts are used!
• Only use system components and options (power sources, welding torches, electrode hold-
ers, remote controls, spare parts and replacement parts, etc.) from our range of products!
• Only insert and lock accessory components into the relevant connection socket when the ma-
chine is switched off.
Requirements for connection to the public mains network
High-performance machines can influence the mains quality by taking current from the mains
network. For some types of machines, connection restrictions or requirements relating to the
maximum possible line impedance or the necessary minimum supply capacity at the interface
with the public network (Point of Common Coupling, PCC) can therefore apply. In this respect,
attention is also drawn to the machines' technical data. In this case, it is the responsibility of the
operator, where necessary in consultation with the mains network operator, to ensure that the
machine can be connected.
2.4 Transport and installation
WARNING
Risk of injury due to improper handling of shielding gas cylinders!
Improper handling and insufficient securing of shielding gas cylinders can cause seri-
ous injuries!
• Observe the instructions from the gas manufacturer and any relevant regulations concern-
ing the use of compressed air!
• Do not attach any element to the shielding gas cylinder valve!
• Prevent the shielding gas cylinder from heating up.

For your safety
Transport and installation

099-00HPXQ-EW501
07.05.2021
CAUTION
Risk of accidents due to supply lines!
During transport, attached supply lines (mains leads, control cables, etc.) can cause
risks, e.g. by causing connected machines to tip over and injure persons!
• Disconnect all supply lines before transport!
Risk of tipping!
There is a risk of the machine tipping over and injuring persons or being damaged itself
during movement and set up. Tilt resistance is guaranteed up to an angle of 10° (ac-
cording to IEC 60974-1).
• Set up and transport the machine on level, solid ground.
• Secure add-on parts using suitable equipment.
Risk of accidents due to incorrectly installed leads!
Incorrectly installed leads (mains, control and welding leads or intermediate hose pack-
ages ) can present a tripping hazard.
• Lay the supply lines flat on the floor (avoid loops).
• Avoid laying the leads on passage ways.
Risk of injury from heated coolant and its connections!
The coolant used and its connection or connection points can heat up significantly
during operation (water-cooled version). When opening the coolant circuit, escaping
coolant may cause scalding.
• Open the coolant circuit only when the power source or cooling unit is switched off!
• Wear proper protective equipment (protective gloves)!
• Seal open connections of the hose leads with suitable plugs.
The units are designed for operation in an upright position!
Operation in non-permissible positions can cause equipment damage.
• Only transport and operate in an upright position!
Accessory components and the power source itself can be damaged by incorrect connection!
• Only insert and lock accessory components into the relevant connection socket when the
machine is switched off.
• Comprehensive descriptions can be found in the operating instructions for the relevant ac-
cessory components.
• Accessory components are detected automatically after the power source is switched on.
Protective dust caps protect the connection sockets and therefore the machine against dirt and
damage.
• The protective dust cap must be fitted if there is no accessory component being operated on
that connection.
• The cap must be replaced if faulty or if lost!
