Shorted capacitors discharge an ac wave that degrades over a short time.
I can't specifically say why, but I assume that they sort-of re-charge
the opposite plate of the capacitor which then discharges kind of like a
swinging pendulum. Look up stuff on Tesla Coil design for more
information on this. The AC discharge is the basis of how a Tesla coil
works.

Of course I'm still half asleep this morning and am probably missing
something here.....

Capacitors discharge
AC so 99% of these machines are AC welders.



I have to question that. How would they discharge AC?
