• a) Other supply cables, control cables, signal and telephone cables, above and below the welding / cutting machine and its equipment,
• b) Radio and television transmitters and receivers,
• c) Computer and other control hardware,
• d) Critical safety equipment, e.g. protection of industrial equipment,
• e) Medical apparatus for people in the vicinity, e.g. pacemakers and hearing aids,
• f) Equipment used for measuring or calibration,
• g) Immunity of other equipment in the environment. The user must ensure that the other equipment in use in the environment is compatible. This may require additional protection measures.
• h) Considering the time during which the welding / cutting operations or other activities take place during the day, the boundaries of the investigation area can be expanded according to the size of the building, the structure of the building and other activities that are being performed in the building.

In addition to the evaluation of the field, evaluation of device installations may also be necessary for solving the interfering effect. In case if deemed necessary, on-site measurements can also be used to confirm the efficiency of mitigation measures.
(Source: IEC 60974-9).
Electromagnetic Interferance Reduction Methods

•  The appliance must be connected to the electricity supply in the recommended manner by a competent person. If interference occurs, additional measures may be applied, such as filtering the network. The supply of the fixed-mounted arc welding equipment must be made in a metal tube or with an equivalent shielded cable. The housing of the power supply must be connected and a good electrical contact between these two structures has to be provided.
•  The recommended routine maintenance of the appliance must be carried out. All covers on the body of the machine must be closed and / or locked when the device is in use. Any changes, other than the standard settings without the written approval of the manufacturer, cannot be modified on the appliance. Otherwise, the user is responsible for any consequences that may possibly occur.
•  Welding / cutting cables should be kept as short as possible. They must move along the floor of the work area, in a side by side manner. Welding / cutting cables should not be wound in any way.
•  A magnetic field is generated on the machine during welding / cutting. This may cause the machine to pull metal parts on to itself. To avoid this attraction, make sure that the metal materials are at a safe distance or fixed. The operator must be insulated from all these interconnected metal materials.
•  In cases where the workpiece cannot be connected to the ground due to electrical safety, or because of its size and position (for example, in building marine vessel bodies or in steel construction manufacturing), a connection between the workpiece and the grounding may reduce emissions in some cases, it should be kept in mind that grounding of the workpiece may cause users to sustain injuries or other electrical equipment in the environment to break down. In cases where necessary, the workpiece and the grounding connection can be made as a direct connection, but in some countries where direct connection is not permissible, the connection can be established using appropriate capacity elements in accordance with local regulations and ordinances.
• Screening and shielding of other devices and cables in the work area can prevent aliasing effects. Screening of the entire welding / cutting area can be evaluated for some specific applications.

Electromagnetic Field (EMF)
The electrical current passing through any conductor generates zonal electric and magnetic fields (EMF). All operators must follow the following procedures to minimize the risk of exposure to EMF;

•  In the name of reducing the magnetic field, the welding / cutting cables must be assembled and secured as far as possible with the joining materials (tape, cable ties etc.).
• The operator’s body and head should be kept as far away from the welding / cutting machine and cables as possible, The electrical current passing through any conductor generates zonal electric and magnetic fields (EMF).

All operators must follow the following procedures to minimize the risk of exposure to EMF;

• In the name of reducing the magnetic field, the welding / cutting cables must be assembled and secured as far as possible with the joining materials (tape, cable ties etc.).
•  The operator’s body and head should be kept as far away from the welding / cutting machine and cables as possible,
•  Welding / cutting and electric cables should not be wrapped around the body of the machine in any way,
• The body of the machine should not get caught between the welding / cutting cables. The source cables must be kept away from the body of the machine, both being placed side by side,
