Plasma Cutting And Laser Cutting Explained
The basic structure of the plasma arc cutting gun is shown in Fig. 4.1. When plasma arc cutting is used, only the current polarity of DC positive connection is used, that is, the workpiece is connected to the positive electrode of the power supply. Transfer arc is used when cutting metal. The method of igniting the transfer arc is related to

3 Basic concepts of Rotating Machines
In DC machines the stator is used as a field and the rotor is used as an armature, while reverse is the case for AC machines, that is, synchronous generators and synchronous motors. The induction motor is another kind of AC machine, which is singly excited; that is, AC supply voltage is only given to the stator and no supply is given to the rotor.

Principles and Working of DC and AC machines
When a dc voltage is applied to the field windings of a dc generator, current flows through the windings and sets up a - - steady magnetic field. This is called FIELD EXCITATION. This excitation voltage can be produced by the generator itself or it can be supplied by an outside source, such as a battery. DC Machines
