Question: What is the primary function of a rectifier in a welding power source?
Answer options: ✅ To convert alternating current (AC) to direct current (DC)
- To increase the voltage of the output
- To filter out impurities from the shielding gas
- To regulate the wire feed speed
Correct answer: To convert alternating current (AC) to direct current (DC)
Explanation: A rectifier is an electrical device that converts alternating current (AC) into direct current (DC). This is essential for DC welding processes like DCEP or DCEN, which require a consistent polarity.
