Summary:
Electrical energy has many advantages over other forms of energy. Probably the greatest of these is the ease with which it may be transformed into heat energy. An electric arc from a welding power source may be considered a transformer of electrical energy to heat energy because the electrical energy is converted into heat during arc welding. Arc welding involves low-voltage, high current arcs between the electrode and the work piece.
An electric arc is a very bright, luminous glow that assumes a nearly conical shape when it is not constricted or compressed. This arc is the result of the successful effort of an electric current to jump across or bridge an air or other gas (argon in GTAW etc.) gap that is introduced in its circuit. This electric arc may be formed when two conductors of an electrical circuit are brought together forming an electrical contact or a short circuit. When they are separated, and if sufficient voltage is available to maintain the current flow, the arc is established and maintained. There is considerable heat created by the resistance introduced into the flow of current by this air/gas gap (which is a poor conductor of electricity). These heated and ionized gases (gas atoms in the presence of an electrical current), are called arc plasma or sometimes called the arc flame.
