 Hi Laurent,

I noticed Caroll's post on the other forum and indeed as she wrote, with DC arc the electrons 'travel' towards the positive wire end, causing more and more 'hot particles' there while they leave the negative wire end, quasy 'cooling' it by moving away from it.

Last night I though of this and this is why I asked about the diodes and you wrote you did not use any so you must have had AC pulse, with alternating polarity, so this could not explain the temperature difference. 

This morning it occured to me however that you had an asymmetry in the output AC pulse when you showed the 350V waveform across the LED lamps with the 500 turns secondary coils, (200V peak positive above the zero crossing and 150V negative peak below zero crossing) so there was a quasy 50V DC shift, a DC polarity 'advantage' at one of the electrodes.  OF course I do not know if your new output coils with the 200 turn (or whatever) windings have a similar amplitude asymmetry around the zero crossing but if you simply made the two output coils onto the different half cores again, chances are there is now again asymmetry between the positive and negative amplitudes. 

rgds,  Gyula 

PS You mentioned you use steel wire where one of the ends is hotter in temperature,  I wonder if your steel wire is ferromagnetic? i.e. a permanent magnet attracts it?

More testing,

lamps = 120V @ 2Watts each.

1 lamp on mains     101.5VAC @ 16ma input = 1.62Watts
2 lamps in series    6.65VDC @ 199ma input = 1.32Watts
2 lamps in parallel  7.25VDC @ 158ma input = 1.08Watts

Here's a scope shot with no load

Hi Michel,

I am curious... 

Where is the zero line on your scope shot above?  And does the amplitude of the pos and neg part of the output pulse changes when you connect the LED lamps?   
IF you dismantled already your setup, then it is ok of course.

Thanks,  Gyula

Hi all

Hi Michel and Gyula

and of course SERGDO if you wish to try to come in the discussion it would be great even in russian thank's !

just my next experiment, really interesting

and some scope shot of the importance of the diode's organisation for a good melting process

I hope you can see it correctly, or do not hesitate to ask for better pix

to resume , on the left part , the 2 serial diodes are working and on the right part , i supressed the "shorting diode ". so only 1 diode bank is working.

so it seems that i get a really better result with the 2 opposing diode banks.

So i wonder if we are not dealing with a shorting coil experiment here   Gyula what do you think   

Good luck at all

Laurent
