I already saw your video, it's nice :D The flyback I use comes from an old small screen TV, it gets warm after some arcing, but not to hot. I tried to push 1000 watts through this thing, the arcs just stay the same length, only they are thicker and melt my negative electrode away. Also the primary coil get's very hot, the driver just stays cool.
@Dri0m If the inductor is too small, it changes the operation of the circuit into a less efficient mode. A bigger inductor is all right as long as it doesn't saturate.
I saw some of your video's, you have a nice flyback! If that mosfets where the IRF640A you commented about earlier I think you pushed to much current trough them. I know IRFP250 mosfets are a bit expensive, but for this circuit they do a great job and are worth the money.

It looks a lot like fire, you should try to cook something with it! Cooking the engineer way. haha

The tip of the electrode you were holding in your hand was getting red hot! That was cool.

Nice, but it is really 800W? I made 20cm (8") arc from flyback at 500W only

Arc length does not indicate power alone, these arcs are really hot, meaning high currents are flowing. More current means more watts.

Yes, I know that, but the voltage of yours looks about the same. Watch my video "monster arcs from flyback", these arcs are as hot as hell :D
But anyway, your arcs are pretty cool, I think any modern transformer I tried did overheat at these powers. I should try the same one as you :)

@jmartis2 bigger current - inductor = longer spark but lower voltage
