The welding arc
A welding arc is an electric discharge between two electrodes. The welding current is
conducted from the electrode to the workpiece through a heated and ionised gas, called
plasma. The voltage drop and current in the arc give the amount of electric power that is
released, the heat of which, melts the electrode and the joint faces.
The power must also be high enough to keep the temperature of the arc sufficient for
the continued transport of the current. The temperature maintains ionisation of the gas,
i.e.it creates electrically charged particles that carry the current.
