Not an expert but the whole premise of these systems is to maintain the
arc, not extinguish it as we desire for TC use.
This was a clear lesson on one of my earlier static gaps. I used dome nuts
on the end of brass rod and some lengths of copper pipe for heat
dissipation. The dome nuts formed hollows in the ends which trapped
heated/ionized gas and the subsequent performance was ABYSMAL !
I would imagine these hollow rods would suffer exactly the same problem
....... unless you forced high pressure air down the middle ..... HMMMM ???
