Recommendation to reduce electro-magnetic emission
a. Mains power supply: the equipment must be connected to the power mains as specified in the Manufacturer’s instructions. If interference
occurs, additional precautions such as filtering of the mains supply may be required. The supply cable in the welding machine’s permanent
installations may have to be screened in metal conduits or similar. The screening should be electrically continuous for the entire length of the
cable. It should also be connected to the welding machine with a good electrical contact between the metal conduit and the casing.
b. Welding cables: The welding cables should be kept as short as possible and should be positioned close together, running at or close to the
floor level.
c. Protection and reinforcement: Selective screening and shielding of other cables and equipment in the surrounding area may alleviate
problems of interference. Screening of the entire welding area may be considered for special applications
d. Connect the earth directly to the metal piece to be welded: Where necessary, the connection of the workpiece to earth should be
made by a direct connection to the workpiece, but in some countries where direct connection is not permitted, the connection should be
achieved by suitable capacitance, selected according to national regulations.
