My First Fractal Burn

These are my first attempts at fractal burning. It took a bit of time to get the equipment safety features organised after I was given a homemade version of a fractal burner powered by a microwave oven transformer.
With a lot of help from my son, who is an electrical engineer, we came up with a unit that was safe but believe you me a bit scary if you a are bit clumsy with safety which I’m not.
What we came up with.
1. A foot pedal operating switch. if you get a high voltage jolt and it throws you the circuit will be cut immediately.
This pedal switch was a good price on eBay

.
2. A Variable Voltage Controller. This is to my mind an essential piece of equipment to control the intensity of the burn particularly when the probes are close together. It is also a secondary safety device if you turn it to zero after each burn.

.
3. I use wooden props to hold the probes as I don’t think it is necessary to hold the probes. It may be a bit slower to do the job that way but much safer as you won’t get a second chance with this gear.
Also I operate with the probes out of reach from the foot pedal switch as an extra safety feature.

.
4. I keep the main components, transformer & voltage controller, in a plastic box with the controller knob on the outside. The high voltage side of the transformer is not exposed then.

.
5. I have deliberately not shown the wiring for this project as that’s for the professionals.
Ps Thanks to Jim Jakosh for his help on this setup.

Nice first burn Grumpy, good to know you took safety into account when constructing the burner. Look forward to seeing more burns. I bought my burner from the US with foot pedal and probes from Conestoga.com.

Well done Grumpy I reckon Pete will be next.

You look like its all covered safety wise and we will be seeing project No2 without any problems as opposed to a funeral notice!

The projects still looks pretty scary just the same, may be LBD is next!

Looks impressive Tony, but not a toy for play; either the equipment of the final work of ark.

Your first burn looks good Tony, Nice to see that you built the burner with safety in mind. Hopefully no accidents; just beautiful work!

Great looking burn, Tony. You will love how you can burn a small pattern on a small object with the nice voltage regulator you have!! Be safe…..........Cheers, Jim

Thanks for your comments Jocks. There is a multitude of things that can go wrong with this project so if you intend to make one get professional advice on the journey

Great burn, nice you had help to get it much safer than one sees on Utube. I also made a safer system but am no electrical engineer, but atleast one can have a sense of safety. Don’t know if you looked at mine. here is the link if interested. I like how you held your electrodes.

Nice look at the equipment, but man I really like that first burn. I like the way it looks like a tree,
