    W A R N I N G !

    Prior to the first commissioning, all persons who are involved withthis machine should read this operating instruction manualcarefully and confirm that they have done so in writing.

    Please keep the operating instruction manual easily accessible forall welders and service staff!

    The best place is the welding machine itself!

    Appendix A (information)

    Installation and useThe user is responsible for the installation and operation of the welding machine according to the manufacturer'sinstructions. If there is electromagnetic interference, the user is responible for finding a solution with the aid ofthe manufacturer of the welding machine, e.g. grounding of the weld current circuit, electromagnetic screeningand/or inlet filter.

    A.1 Evaluation of the areaBefore installing the welding machine, the user has to evaluate any possible electromagnetic problems in thesurrounding area. The following must be taken into consideration:

    a) Other mains supply lines, control lines, signal and telecommunication lines above, below and nextto the welding machine.

    b) Radio and TV broadcasting station and receiver.c) Computer and other control units.d) Safety devices, e.g. protection for commercial equipment.e) Health of persons in vicinity, e.g. if using pacemakers and hearing aids.f) Units for calibration or measement.g) Resistance to interference of other equipment in the surrounding area. The user must ensure that

    other equipment used in the vicinity is electromagnetically compatible. This may require additionalsafety measures.

    h) The time of day when welding or other activities are being carried out.

    The extent of the surrounding area to be considered depends on the construction of the building and otheractivities which take place there and may exceed the boundaries of the property.

    A.2 Procedure to reduce emissions

    A.2.1 Mains supplyThe manufacturer recommends that the welding equipment is connected to the mains supply. Where there issome interference, additional safety precautions may be necessary, i.e. filter for the power supply.

    A.2.2 Maintenance of the welding equipmentRegular maintenance intervals are recommended by the manufacturer.

    A.2.3 Weld cablesWelding cables should be as short as possible and should be run close together on or near to the floor.

    A.2.4 Potential equalizationThe electric connection of all metal parts in and near a welding machine should be taken into account. The metalparts connected to the workpiece may increase the risk of an electric shock if the welder touches these metalparts and the electrode at the same time. The welder should be protected against all connected metal parts.

    A.2.5 Earth connection of workpieceIt must be ensured that earthing of the workpiece does not increase the risk of accident to the user or causesdamage to other electrical equipment.

    A.2.6 ScreeningSelective screening of other cables and equipment in the vicinity may reduce electrical interference. Screeningof the complete welding equipment may be considered in special situations.
