train]] .]] An electric arc is an . An archaic term is '''voltaic arc''' as used in the phrase "voltaic arc lamp". The various shapes of electric arc are Emergent Properties of nonlinear patterns of Current and Electric Field . The arc occurs in the gas-filled space between two conductive Electrodes (often made of Carbon ) and it results in a very high Temperature , capable of Melting or Vaporizing virtually anything. Electric arc is a continuous discharge, while a similar electric Spark discharge is instant and momentary. On a commercial basis, electric arcs are used for Welding , Plasma Cutting , for Electrical Discharge Machining , as an Arc Lamp in Movie Theater Projectors and Followspot s in Stage Lighting . Electric Arc Furnace s are used to produce Steel and other substances. Calcium Carbide is made in this way as it requires a large amount of energy to promote an Endothermic Reaction (at temperatures of 2500 °C ). Low-pressure electric arcs (more often referred to as Glow Discharge s) are used for lighting, e.g., Fluorescent Tubes , mercury and sodium Street Lamps , camera flash lamps, Plasma Display s, and Neon Sign s. Undesired or unintended electric arcing can have detrimental effects on Electric Power Transmission and Distribution systems and Electronic equipment. SEE ALSO EXTERNAL LINKS
