Foreword
Electric and Magnetic Fields
During the operations of the welding machine an electromagnetic field (EMF) can be
created and may caused health problems.
The operator is responsible for the proper installation and use of the device according to the
manufacturer's instructions. In case of electromagnetic interference, it's in the responsibility
of the user to remove these (technical support can be requested).
Before the installation and commissioning of the equipment, the user has to consider
potential electromagnetic interference in its environment.
The following should be considered:
 Other supply, control, signal and telephone cables over, under and in the adjacent
area of the welding machine.
 Radio, television sets and receivers.
 Computer and other control devices.
 Security and surveillance equipment.
 The health status of all attendant persons, especially people with heart pacemakers,
hearing aids, etc.
 Instruments and equipment used for the calibration.
 The protection of the other devices in the vicinity of the welding unit. These must be
compatible. Additional precautions may be necessary.
 The time of day in which the welding or other work will be performed.
Recommendation to reduce the electromagnetic interference
 Installation of a filter on the supply.
 Use of cables with protective wrapping.
 Proper maintenance of the system.
 The housing must be tightened during the operation.
 The weld cables as short as possible.
 Grounding of the work piece.
