Hey guys. Found this old microwave transformer.
I see the bottom is the low side as the conductor is larger and there are fewer windings. Is this where I input myou 120v single phase power?
What leads would I come off to produce an arc between for etching wood as per the hobby.
Thanks for all your help.
I've already spliced and made the 120V connection. Was I supposed to use the ground on the 120v power in anywhere? I don't see any connection points.
I tried and am having no luck. I was under the impression that the high side of the transformer is a single wire in a coil. If I touched them together after injecting power on the low side aren't the supposed to arc?

Primary Coil: the one with the thicker wire, which has fewer wraps, that you connect to your 120VAC power mains
Secondary Coil: the one with the thinner wire, which has more wraps, produces the kilovolts and death and arcing
Sometimes there is a 3rd coil which only has a few turns of wire. Don't use that one. It can be removed.
The frame needs to be grounded.
Is that your MOT in the image? That looks like the top is the secondary coil and the bottom is the primary coil. The 2 white wires on the bottom should be the 120VAC connection.
The top coil looks like it has 3 wires, including the one coming off that top tab. The short white wire with the blur tab should be the secondary coil wire, you can see the other end of it attached to the frame right behind it in that image. Those other two thick wires should be the 3rd coil. Ignore those, just safely secure them so they don't touch anything.
The arc will travel between the frame and that short white wire on the top.
Remember, keep one hand behind your back at all times.

This guy sounds like a Norwegian bachelor farmer.
Did OP die?

I hope so. If you can't figure out how a MOT works then you're dumb to play around with high voltage
Bruh, Git gud.

I literally yanked that out of a microwave in an hour, watched a youtube vid, hooked up a pair of jumper cables and i was GTG. Shit aint hard, just dangerous.
>>1135011
yeah but you did it on a meme stock, and it doesn't even look good
>>1135032
Eat shit fag, whatve you done with your projects? At least i did something.
>>1135035
I made a desk out of an old barn door and way too much money in iron pipe
>>1135037
And that looks so much nicer and less of a meme than what I did. Congrats.
>>1135032
It looks great. You're just very jelly or contrarian.

Off topic, but why lichtenburg? Please elaborate, that name means things to me.
>>1135333
Because you can do awesome wood burning figuring with it.

Seriously, just look at the pic I put up, look heres the exact same thing but bigger. Note how the wall power connects an how the jumper cable connects, one side to the lead wire, the other just clamped on the metal frame. I used the plug from the microwave I tore it out of, and teh existing power connections. I even insulated it with a cheap ass plastic kennel for safety.
once again git gud fag.

Aren't you supposed to moisten the wood with soda solution or something?
>>1135393
saturated salt water, saturated baking soda, fucking gatorade would work. Anything that is conductive, regular water would work just not very well, i used salt water, but it takes like a pound of salt so ive heard baking soda will work with less.

Thats good to know that fumes are a thing, Naturally i just did it outside since it does get really smokey from the burning wood. Whats your youtube channel? No bully I promise.

Yes. This is the HV secondary.
>the other end of it attached to the frame right
Could be the other end of the HV winding, grounded to the frame. Or a shield ground in the core. Check the HV terminal (white wire) for continuity to the frame with an ohmmeter. If it is, the HV will be the white wire and the frame.
If the HV secondary is not grounded to the frame, check continuity to the other two wires coming out of the HV section. These are a third winding which produces a couple of volts for the magnetron filament. Sometimes the filament winding is tied to one end of the HV coil.
