Electromagnetic emissions and the radiation of electromagnetic disturbances
This welding equipment for industrial and professional use is in
conformity with the European Standard EN/IEC60974-10 (Class
A). The purpose of this standard is to prevent the occurrence of
situations where the equipment is disturbed or is itself the source
of disturbance in other electrical equipment or appliances. The
arc radiates disturbances, and therefore, a trouble-free
performance without disturbances or disruption, requires that
certain measures are taken when installing and using the
welding equipment. The user must ensure that the operation of
the machine does not occasion disturbances of the above men-
tioned nature. The following shall be taken into account in the
surrounding area:
1. Supply and signalling cables in the welding area which are
connected to other electrical equipment.
2. Radio or television transmitters and receivers.
3. Computers and any electrical control equipment.
4. Critical safety equipment e.g. electrically or electronically con-
trolled guards or protective systems.
5. Users of pacemakers and hearing aids etc.
6. Equipment used for calibration and measurement.
7. The time of day that welding and other activities are to be
carried out.
8. The structure and use of buildings.
If the welding equipment is used in a domestic establishment it
may be necessary to take special and additional precautions in
order to prevent problems of emission (e.g. information of tem-
porary welding work).
Methods of reducing electromagnetic emissions:
1. Avoid using equipment which is able to be disturbed.
2. Use short welding cables.
3. Place the positive and the negative cables close together.
4. Place the welding cables at or close to floor level.
5. Remove signalling cables in the welding area from the supply
cables.
6. Protect signalling cables in the welding area, e.g. with
selective screening.
7. Use separately-insulated mains supply cables for sensitive
electronic equipment.
8. Screening of the entire welding installation may be considered
under special circumstances and for special applications.
WARNING
Arc welding and cutting can be dangerous to the user, people working nearby, and the surroundings if the
equipment is handled or used incorrectly. Therefore, the equipment must only be used under the strict
observance of all relevant safety instructions. In particular, your attention is drawn to the following:
Electricity
-
The welding equipment must be installed according to safety regulations and by a properly trained and qualified
person. The machine must be connected to earth through the mains cable.
-
Make sure that the welding equipment is correctly maintained.
-
In the case of damaged cables or insulation, work must be stopped immediately in order to carry out repairs.
- Repairs and maintenance of the equipment must be carried out by a properly trained and qualified person.
- Avoid all contact with live components in the welding circuit and with electrodes and wires if you have bare hands.
Always use dry welding gloves without holes.
- Make sure that you are properly and safely earthed (e.g use shoes with rubber sole).
- Use a safe and stable working position (e.g. avoid any risk of accidents by falling).
Light and heat emissions
- Protect the eyes as even a short-term exposure can cause lasting damage to the eyes. Use a welding helmet with
suitable radiation protection glass.
- Protect the body against the light from the arc as the skin can be damaged by welding radiation. Use protective
clothes, covering all parts of the body.
- The place of work should be screened, if possible, and other persons in the area warned against the light from the arc.
Welding smoke and gases
- The breathing in of the smoke and gases emitted during welding is damaging to health. Make sure that any exhaust
systems are working properly and that there is sufficient ventilation.
Fire hazard
- Radiation and sparks from the arc represent a fire hazard. As a consequence, combustible materials must be removed
from the place of welding.
- Working clothing should also be secure against sparks from the arc (e.g. use a fire-resistant material and watch out for
folds and open pockets).
- Special regulations exist for rooms with fire- and explosion hazard. These regulations must be followed.
Noise
- The arc generates acoustic noise according to welding task. In some cases, use of hearing aids is necessary.
Dangerous areas
-
Special consideration must be taken when welding is carried out in closed areas or in heights where there is a danger
of falling down.
Positioning of the machine
-
Place the welding machine so there is no risk that the machine will tip over.
- Special regulations exist for rooms with fire- and explosion hazard. These regulations must be followed.
Use of the machine for other purposes than it is designed for (e.g. to unfreeze water pipes) is strongly deprecrated. If
occasion should arise this will be carried out without responsibility on our part.
Read this instruction manual carefully before the equipment is installed and in operation
