SAFETY Electromagnetic Compatibility (EMC) The size of the surrounding area to be considered will depend on the structure of the building and other activities that are taking place. The surrounding area may extend beyond the boundaries of the premises. Methods of Reducing Emissions Mains Supply Welding equipment should be connected to the mains supply according to the manufacturer’s recommenda- tions.
