Man how many joules did you put into this (launcher?) you make me a bit etchy knowing i dump 1KJ-4KJ into 10awg stranded wire now...xD Here's the best super-macro pictures i could get with my camera indoors. Force-exposure, as my camera likes light. This is casio EX-FH20, 20X optical zoom. Rather amazing it can do super macro, and 20X optical, if you ask me.

First one is 00 grade steel wool

About 2kJ on a 4 squared millimeters (european standard) cable.
for your information a 10AWG is equivalent to 5.27 sqmm and at the moment i never had any problems with a 10sqmm cable (near equivalent to 7 AWG) even at full power (2.8kJ) but for safety reasons and for better performances i usually prefer the other two coils made with a 16sqmm and 25sqmm cables (closer to 5 and 3 AWG)



Ciao!
Fabio.
