I have a arc welder.
80V open circuit
30V closed circuit
20% duty cycle
I want to build a arc stabilizer for it. Not a "High Frequency stabilizer".
I have seen inductors placed after the rectifiers in series with one of the output leads. This is what I want to do, but I want to understand the how and why.
What does the inductor do in the circuit? Is it the inductance or the reactance or both that is doing what needs to be done? What is goal trying to be accomplished, voltage drop, current rise delay, etc.. What are the formulas and constants used to design the inductor used as a arc stabilizer.
Is there such a thing as a AC arc stabilizer or are they only for DC?
Does the duty cycle affect the size of inductor, length, diameter, or gauge of wire used?
Thank you for your time.
