In arc welding process, the high quality alternator functions at what

1.	In arc welding process, the high quality alternator functions at what frequency?(a) 250 Hz(b) 300 Hz(c) 350 Hz(d) 400 HzI have been asked this question by my school principal while I was bunking the class.I would like to ask this question from Arc Welding topic in division Welding and Related Processes of Casting-Forming-Welding II
Answer» The correct choice is (d) 400 Hz Explanation: In an arc WELDING process, there are ALTERNATORS used for producing high current and function at lower FREQUENCY, and there are alternators which are of high quality and work at high frequency. The FUNCTIONING frequency of these alternators is 400 Hz.
