The big MOT un-ballasted.

I decided to try and get some better arcs from the big MOT I have, running it completely un-ballsted I can get some pretty good bright fat roaring arcs out of it. The only trouble is they were too bright for the camera and came out over-exposed and just look like bright blobs on the video.

The primary of this MOT is only about 1.4 ohms which I think is quite low, even for a MOT, but it only pulls 0.9 amps un-loaded at the full 240 volts which is about a third of what most MOTs pull un-loaded, so this one is pretty efficient by MOT standards. The current draw when drawing arcs is about 11 amps and I can do this for quite a while without it getting hot.

So an MOT is a microwave oven transformer? I couldn't watch the video because of my internet or something but that is one huge transformer on the left. Did you use a power supply or is it connected straight to the wall?

@0UT3RL1M1T5 Yes a MOT is a Microwave Oven Transformer, and I did connect it straight to the wall

How many watts was that microwave you got that out of?

[CoolDudeClem]

@teslabang I'm not sure how many watts it was, all i can remember is that is was quite a big one.

your hand was shaking a lot haha

[CoolDudeClem]

@marcvie9 My hands always shake, that's why the picture is always shaky when I hold the camera, even with the image stabilizer on, but the stabilizer on my camera is pants anyway.

@ 2:30 did you say "Get that on your willy you'd know all about it"?

[Films4You]

Clem, you are suppost to laugh madly and say "It's alive, It's alive," at 2:16

Nice find. Lots of iron in that baby. A good project transformer.

Taller, taller!

@CoolDudeClem ok nice video anyway

@CoolDudeClem find a cheap plug in air purifier and take it apart, if you got the right one all that will be inside is an induction motor and a small 5kv dc cascade that connects directly to mains , take the output and put it in the middle of the begining of the jacob ladder, this should make the spark start on its own, or just do the same with your flyback transformer.

@CoolDudeClem if you go into video tools or something on youtube there is a 'stabilize video' or something option :)

Great ladder. Be very careful though matey
