Page 8: Electromagnetic Compatibility（Emc
ELECTROMAGNETIC COMPATIBILITY（EMC） ELECTROMAGNETIC EMISSION All electrical equipment generates small amounts of electromagnetic emission due to current transferring in ● the equipment. Electrical emission may be transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions are received by other equipment, electrical interference may result . Electrical emissions may affect not only welding machines but also many kinds of electrical equipment like radio and TV reception, numerical controlled machines, telephone systems, computers etc. -
