Question

What is the value of the voltage used in PBM process?

(a) 0.1 – 20 V

(b) 30 – 250 V

(c) 300 – 400 V

(d) 500 – 600 V

I got this question during an online interview.

My query is from Plasma Beam Machining-Introduction And Machining system topic in section Thermal Processes of Advanced Machining

Answer 1

The correct option is (b) 30 – 250 V

For explanation I would say: The value of voltage in the Plasma beam machining processes is about 30 – 250 V.
