Type of DC Generator used for Arc Welding
The correct option for the type of DC generator used for arc welding is option D, which is a shunt generator. Let's understand why a shunt generator is used for arc welding.
What is a Shunt Generator?
A shunt generator is a type of DC generator where the field winding is connected in parallel or shunt with the armature winding. The voltage generated by a shunt generator remains almost constant with varying loads.
Why Shunt Generator is Used for Arc Welding?
Arc welding requires a constant current source. A shunt generator provides a constant output voltage which can be converted into a constant current by using a suitable resistance in the circuit. As the shunt generator's output voltage remains constant, it is suitable for arc welding.
Advantages of Using Shunt Generator for Arc Welding
1. Provides a constant output voltage which is essential for arc welding.
2. The voltage can be easily converted into a constant current.
3. The shunt generator is easy to maintain and repair.
4. It is a cost-effective option for arc welding.
Conclusion
In summary, a shunt generator is used for arc welding as it provides a constant output voltage which is essential for converting it into a constant current. The shunt generator is easy to maintain, repair, and cost-effective option for arc welding.
