Hi guys as we all love arcs I thought I'd share a video of my homemade flyback running at about 3Kw from a isolation transformer off a full bridge of 60N60s

Excuse the M10 bolts ;D I lashed it up quick to see some arcs
-
The M10 bolts are excused! Those are some nice arcs, though there always seems to be something missing without the 100Hz hum from mains :P
-
But it does have that "click" when first striking! Nice sparks from such a small food box :)
What kind of driver/control are you using for the 60N60 bridge?
-
Hi Mads, I work in welding/engineering and I can take home old disused welding equipment so I took a few welding inverter boards and "remanufactured" them into a power bridge for my flyback and I guess they would make a powerful induction heater too, this uses sd6835 and I added 4 60N60DLF IGBTs

This board uses current mode control in the new video terrible build quality though as that's all I had on hand :-*
Hard to see the arcs but massive current as alot of UV being emitted I can stretch them too 2 feet when done fast
