0.8mm +/- 0.4 is ballpark. zinc anodised mild steel, but wrapped in PTFE/FeTi powder. Wire dia 0.8mm-TBC. From the specs of the welder it pushes out 200A up to 70v, initial voltage at breakdown would obviously be much higher. (As soon as I have a shunt I’m confident with I’ll measuring the pulse). The welder produces the pulsed waveform.

The two examples of partial and full anode penetration were completely dry, suspect the PTFE may have provided the H. The third example which is intact was the wetted sample, it had two little indentations.
I have some SS wire to try next. But most importantly I’m planning on doing this experiment in the centre of a bagel reciever. If the BL has significant TDL, we’ll measure it!
I’ve measured lower power, HV sparks. The V output of the bagel winding is very interesting, lots of action prior to the main arc discharge, spikes of pulses in both polarity. Looking forward to measuring the BL. Exciting times.
