DC Generator for Arc Welding Purposes

DC generators are used for various applications in the electrical industry, and one of the primary applications of DC generators is arc welding. Arc welding is a process that generates intense heat through the use of an electric arc between an electrode and the base material. This heat is used to melt and fuse metal pieces together.

Type of DC Generator Used for Arc Welding

The type of DC generator used for arc welding purposes is a differentially compounded generator. This type of generator has two sets of field windings: one is a shunt field winding, and the other is a series field winding. The shunt field winding controls the voltage output of the generator, while the series field winding controls the current output of the generator.

Advantages of Differentially Compounded Generator

The differentially compounded generator has several advantages over other types of DC generators, making it the preferred choice for arc welding purposes. Some of these advantages include:

1. High Current Output: The series field winding in the differentially compounded generator helps to boost the current output of the generator, making it ideal for arc welding applications.

2. Smooth Voltage Regulation: The shunt field winding in the differentially compounded generator helps to regulate the voltage output of the generator, ensuring a smooth and consistent output.

3. Ability to Handle Heavy Loads: The differentially compounded generator is capable of handling heavy loads, making it suitable for industrial applications.

Conclusion

In conclusion, the differentially compounded generator is the preferred choice for arc welding purposes due to its high current output, smooth voltage regulation, and ability to handle heavy loads. Its two sets of field windings make it ideal for controlling both voltage and current output, which is essential for arc welding applications.
