Ok, thanks everybody. one moment, i have hoped that we could weld under the 15 volts and why not with only one or two parallel caps@2.5V ; so in this set the esr should be correct...But, not possible...well understood, so i retain the rockford fosgate and others indications from Texaspyro. I'm...

ok the link is failed...sorry. so go to mouser>supercapacitors > apply the filter by choosing low esr...You find 22 results...

Hi, Sokapu, Texaspyro and every body. "52F is very, very big, probably massively too big for a CD welder for this application. I can blow holes in the end of cells with just under 2F at 20V, which equates to about 400 Joules of energy. Even at the lowest practical voltage for a welder of this...

yes, ok...but what' s the trouble when you increase the capacitance of the circuit?, because I see few ultra capacitors which have very very low ESR ( bcap1200p270T05=0,56 mohm!!!) much better than audio car caps . I remember the threaads p 32 of this forum ( thanks to cesare250495 and Jeremy...

hello guys Is anybody knows what do you think about ultra capacitors ( maxwell and others) for cd welder application or for high pulse discharge machining? How compare these caps to the audio caps??? and why??? Thanks to the fantastics men.... :D
