Instructions for the installation and operation of an arc welding device to prevent possible electromagnetic interference:
As the manufacturer, we recommend that the following assessments and measures be carried out by a qualified electrician.
General
The user is responsible for setting up and operating the arc welding machines/cutting equipment in accordance with the manufacturer's instructions. If electromagnetic interference is detected, it is the responsibility of the user of the arc welding machines/cutting equipment to find a solution with the technical assistance of the manufacturer. In some cases, the measure needed may simply consist of earthing the welding circuit (see note). In other cases, it may include complete electromagnetic shielding of the power source of the arc welding machine/ cutting equipment and the workpiece, combined with input filters. In all cases, electromagnetic interference must be reduced until it no longer causes any disturbance.
Note
The approach taken to earthing the welding circuit depends on the local safety regulations.
Changing the earthing to improve electromagnetic compatibility may increase the risk of
accidents or damage to equipment
Assessing the surroundings
Before setting up the arc welding machines and/or cutting equipment, the user must assess possible electromagnetic problems in the surroundings.
When doing so, the following factors must be taken into account:
a) other mains cables, control cables, signal and telecommunication cables above, below and next to the arc welding machines and/or cutting equipment;
b) Audio and television broadcast transmitters and receivers;
c) Computers and other control devices;
d) Safety equipment, e.g. protection for commercial facilities;
e) the health of persons nearby, e.g. those using pacemakers and hearing aids;
f) Calibration and measurement equipment;
g) the resistance of other equipment in the vicinity to interference. The user must ensure that
other equipment used in the environment is suitable for such a purpose. This may require additional protective measures;
h) the time of day during which the welding, cutting, or other activities must be carried out.
The extent of that surrounding area that must be considered depends on how the building is constructed, and the other activities taking place there. This area may extend beyond the limits of the premises
Evaluation of the welding machine / cutting equipment
In addition to the assessment of the area, the arc welding machines/cutting equipment can be evaluated to assess and resolve cases of interference. An assessment of electromagnetic interference should include in situ measurements, as specified in section 10 of CISPR 11:2009. In-situ measurements can also be made to gauge the effectiveness of any minimisation measures implemented.
Guidance for minimisation measures:
Public power supplies
Welders machines/cutting equipment should be connected to the public power supply as per the manufacturer's recommendations. If there is any interference, it may be necessary to take additional precautions, such as fitting filters for the mains connection. Consider shielding the mains cable of permanently installed welding machines/cutting equipment with a metal pipe or similar. The shielding should be electrically connected for its entire length. The shielding should be connected to the welding machine/ cutting equipment power source to achieve good electrical contact between the sheath and the housing of the welding machine/cutter power source.
Maintenance of the arc welding machines/ cutting equipment
Arc welding machines/cutting equipment should be regularly maintained as per the manufacturer's recommendations. All access and service doors and covers should be closed and well secured when the welding machine/ cutting equipment is in operation. With the exception of the changes and adjustments specified in the manufacturer's instructions, the welding machines/cutting equipment should not be modified in any way. In particular, the spark gaps of arc ignition and stabilisation devices should be adjusted and maintained in accordance with the manufacturer's recommendations.
Welding cables
Welding cables should be as short as possible, close together, and should run across or near the ground.
Electrical bonding
The electrical interconnection of all metallic parts in and next to a welding machine/cutting equipment should be taken into consideration. Metallic parts connected to the workpiece can increase the risk of the welder receiving an electric shock from touching these metallic parts and the electrode at the same time. The welder should be electrically insulated from all of these connected metal parts.
Earthing the workpiece
It may be that the workpiece is not already connected to earth for reasons of electrical safety or because of its size and location, e.g. a ship's hull or steel structures. If so, grounding the workpiece can reduce emissions in some, but not all, cases. Ensure that earthing the workpiece does not increase the risk of accident for the user or cause the destruction of other electrical equipment. If necessary, the workpiece must be grounded by a direct connection to the workpiece. In countries where a direct connection is prohibited, the connection should be achieved using suitable capacitors, selected in accordance with national regulations.
Screening
Selective screening of other cables and equipment in the vicinity can reduce irradiation. The screening of the entire welding/cutting set-up may be considered for special applications.
Class A (IEC 60974-10):
If you intend to use the apparatus in residential surroundings supplied by the low voltage mains supply, an electromagnetic filter may be required to suppress electrical disturbance to a level where they will no longer be a nuisance to the user.
The apparatus may be used in industrial or other areas where power is not supplied by municipal LV mains.
Class A apparatus are not intended for use in residential areas where power is supplied via municipal LV mains, since unfavourable power conditions may cause interference. As a user, you must make sure, after consultation with your energy provider, if necessary, that your point of connection on which the machine is to be operated meets the requirements above.
The user is responsible for faults arising from the welding.
