Electrical Engineering XYZ MCQs
Which of the following generators are used in arc welding:
- Cumulative compound generators
- Differential compound generators
- Shunt generators
- Series generators
Correct answer: 2. Differential compound generators
Explanation: Differential compound generators have the advantage of being able to adjust their voltage output to some extent based on the load. This capability can help maintain a stable welding arc even when there are fluctuations in the welding conditions or the type of material being welded.
