Inductance. In electromagnetism and electronics, inductance is the property of a conductor by which a change in current in the conductor induces a voltage in both the conductor itself and in any nearby conductors.
Inductance is the property in an electrical circuit that slows down the rate of current rise, Fig. 2. The current travelling through an inductance coil creates a magnetic field. This magnetic field creates a current in the welding circuit that is in opposition to the welding current. Increasing the inductance will also increase the arc time and decrease the frequency of short-circuiting. For each electrode feed rate, there is an optimum value of inductance. Too little inductance results in excessive spatter. If too much inductance is used, the current will not rise fast enough and the molten tip of the electrode is not heated sufficiently causing the electrode to stub into the base metal.
