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 6 Maintenance, care and disposal 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 the document!
This document is valid only in combination with the operating instructions for the
product being used!
•Read and observe the operating instructions for all system components, especially the
safety instructions!
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!
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!
