2.3 General
DANGER
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! (see Maintenance and Testing chapter)
•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
necessary).
Do not carry out any unauthorised repairs or modifications!
To avoid injury and equipment damage, the unit must only be repaired or modified by
specialist, skilled persons!
The warranty becomes null and void in the event of unauthorised interference.
•Appoint only skilled persons for repair work (trained service personnel)!
Electric shock!
Welding machines use high voltages which can result in potentially fatal electric shocks
and burns on contact. Even low voltages can cause you to get a shock and lead to
accidents.
•Do not touch any live parts in or on the machine!
•Connection cables and leads must be free of faults!
•Switching off alone is not sufficient!
•Place welding torch and stick electrode holder on an insulated surface!
•The unit should only be opened by specialist staff after the mains plug has been
unplugged!
•Only wear dry protective clothing!
•Wait for 4 minutes until the capacitors have discharged!
WARNING
Validity of this document!
This document is only valid in combination with the operating instructions for the
power source being used (welding machine)!
•Read the operating instructions, in particular the safety instructions for the power source
(welding machine)!
Risk of accidents if these safety instructions are not observed!
Non-observance of these safety instructions is potentially fatal!
•Carefully read the safety information in this manual!
•Observe the accident prevention regulations in your country.
•Inform persons in the working area that they must observe the regulations!
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!

WARNING
Risk of injury due to radiation or heat!
Arc radiation results in injury to skin and eyes.
Contact with hot workpieces and sparks results in burns.
•Use welding shield or welding helmet with the appropriate safety level (depending on the
application)!
•Wear dry protective clothing (e.g. welding shield, gloves, etc.) according to the relevant
regulations in the country in question!
•Protect persons not involved in the work against arc beams and the risk of glare using
safety curtains!
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!
Fire hazard!
Flames may arise as a result of the high temperatures, stray sparks, glowing-hot parts
and hot slag produced during the welding process.
Stray welding currents can also result in flames forming!
•Check for fire hazards in the working area!
•Do not carry any easily flammable objects such as matches or lighters.
•Keep appropriate fire extinguishing equipment to hand in the working area!
•Thoroughly remove any residue of flammable substances from the workpiece before
starting welding.
•Only continue work on welded workpieces once they have cooled down.
Do not allow to come into contact with flammable material!
•Connect welding leads correctly!
Danger when coupling multiple power sources!
Coupling multiple power sources in parallel or in series has to be carried out by
qualified personnel and in accordance with the manufacturer's guidelines. Before
bringing the power sources into service for arc welding operations, a test has to verify
that they cannot exceed the maximum allowed open circuit voltage.
•Connection of the machine may be carried out by qualified personnel only!
•When decommissioning individual power sources, all mains and welding current leadshave
to be safely disconnected from the welding system as a whole. (Danger due to inverse
voltages!)
•Do not couple welding machines with pole reversing switch (PWS series) or machines for
AC welding, as a minor error in operation can cause the welding voltages to be combined.
CAUTION
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!

CAUTION
Obligations of the operator!
The respective national directives and laws must be observed for operation of the
machine!
•National implementation of the framework directive (89/391/EWG), as well as the
associated individual directives.
•In particular, directive (89/655/EWG), on the minimum regulations for safety and health
protection when staff members use equipment during work.
•The regulations regarding work safety and accident prevention for the respective country.
•Setting up and operating the machine according to IEC 60974-9.
•Check at regular intervals that users are working in a safety-conscious way.
•Regular checks of the machine according to IEC 60974-4.
Damage due to the use of non-genuine parts!
The manufacturer's warranty becomes void if non-genuine parts are used!
•Only use system components and options (power sources, welding torches, electrode
holders, 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
machine is switched off.
Damage to the machine due to stray welding currents!
Stray welding currents can destroy protective earth conductors, damage equipment and
electronic devices and cause overheating of components leading to fire.
•Make sure all welding leads are securely connected and check regularly.
•Always ensure a proper and secure electrical connection to the workpiece!
•Set up, attach or suspend all conductive power source components like casing, transport
vehicle and crane frames so they are insulated!
•Do not place any other electronic devices such as drillers or angle grinders, etc., on the
power source, transport vehicle or crane frames unless they are insulated!
•Always put welding torches and electrode holders on an insulated surface when they are
not in use!
Mains connection
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.
