A transformer for a wood burner is a device designed to supply voltage to the device. The art of applying a design using wood burning has been around for more than two thousand years; there are many craftsmen who are not only inspired by their hobby, but have also been able to monetize it. Despite this, transformers of this type are not often found on sale on the Russian equipment market, and if they are, they have a high price.
The design features of the technique are simple, so a novice pyrography enthusiast can make a wood burner with his own hands from a transformer. But to do this, you need to know the technical characteristics of the product, design features and protection methods.
How to make a wire burning tip
Wire nozzle for burning
You can independently make nozzles of the required shape from wire. The most popular designs of wire nozzles include beak-shaped and spoon-shaped nozzles.
When making your own nozzle, always remember that the quality of your future projects largely depends on the accuracy and correctness of the nozzle. The main material for creating a wire nozzle is nichrome wire with a diameter of 0.5 to 1 mm.

Making a spoon-shaped nozzle
A spoon nozzle is essentially a regular wire nozzle with a small loop at the tip. This attachment, just like the previous one, can be easily made independently, and from the same beak-shaped attachment. To do this, it is enough to flatten its tip (beak) on something hard, for example, a small anvil or on the head of a hammer mounted in a vice or on the body of the vice itself, if they are strong enough.
Wire nozzle for burning
When flattened, burrs may appear that distort the profile of the nozzle and must be removed by carefully treating the nozzle with sandpaper or a needle file.
Many burning kits you can buy in stores come with a set of wire tips, so don't forget that.

3. Make sure that there are no objects near the work site that could easily catch fire and cause a fire. Of course, it is better not to start work if any malfunctions are detected. 4. During operation, use the soldering iron carefully, do not drop it or use it as a hammer. 5. When soldering, beware of splashes of liquid solder and do not touch the heated areas of the soldering iron. 6. When taking breaks from work, place the hot soldering iron on a non-flammable surface. Do not pull the plug out of the socket by the wire. If you need to leave your workplace, turn off the soldering iron. 7. When soldering, tinning and working with acids, use rubber gloves and safety glasses, and use tweezers for these purposes. 8. All chemicals used for soldering must be kept in glass containers and ground glass stoppers, because acids are quite dangerous and harmful. Each container must have an inscription with the name of the substance that is stored in it. 9. Pickling of products before soldering and pickling of acid for the production of zinc chloride should only be carried out in a well-ventilated area. 10. Be careful with soldering acids. Do not spill them on the table, floor, clothes or shoes. Do not touch it with your hands and under no circumstances try it on your tongue, especially zinc chloride (acid). 11. After finishing work, carefully turn off the soldering iron. Clean up your work area. Put back the tools you used and the sulfuric acid. Let the soldering iron cool down, after which it can also be put back in place. 12. After work, be sure to wash your hands with soap.
Safety rules when working with pliers 1. Before work, check the serviceability of the tool. 2. Never use pliers as a hammer. Such abuse will most likely result in tool failure. 3. Only bite off hardened wire with pliers designed for this purpose. 4. Always cut the wire at right angles. Never move the pliers from side to side or bend the wire back and forth away from the cutting edges. 5. When working with pliers, do not hold the wire at face level. 6. When working, do not place the fingers of your left hand (if you are left-handed, then behind the fingers of your right hand) between the cutting edges. 7. Hand the tool to a friend with the handles first and closed. 8. After work, put the tool back in its place.

How to make it yourself
A wood burner should not only be multifunctional and convenient, but also safe. Requirements apply to the design; if they are not met, the novice master risks his health. Requirements:
- the possibility of a simple pattern of needles, threads, wires, feathers used in burning;
- Convenience of adjusting the voltage supply by adjusting the handle;
- the ability to change the temperature without turning off the device from the network;
- use of a transformer with the required current and voltage indicators, fashionability;
- connection to a power source - the power supply unit must be suitable for the type used by the electrical network.
The main characteristic of the transformer unit is power indicators. They should not be less than 200 V.
The remaining characteristics of the device are optimally not so significant. If you choose a transformer with lower power characteristics, it will overheat due to contact with needles having large cross-sections. An option that is too large in terms of power will show high voltage parameters, which will negatively affect operating efficiency. Required:
- remove the top winding completely;
- leave the primary in place;
- rewind the secondary winding (use insulated wire with a minimum cross-section of 2 millimeters);
- calculate the required number of turns for the input voltage - you will need to eliminate incorrect options experimentally; to do this, wind a certain number of turns, connect the equipment to the network and calculate what the input voltage will be;
- Having selected the optimal option, set the number of turns.
After installing the transformer, the output voltage level of the device is adjusted. The equipment is equipped with special rods for attaching needles, wires and feathers, and handles are installed.
It’s easy to assemble a homemade wood burner yourself, if you have a transformer with the necessary characteristics and know the laws of physics. The equipment will become a tool for creative personal development, for which you won’t have to pay the lion’s share of the budget.

design of a tip for wood burning on a machine
then we insert it tightly into the inside of our case and on top we wrap nichrome, I have 0.5 mm so that it turns out like this
Well, we put it on the machine, I have a floating head on a bearing, it works from both the Z axis and an electromagnet
attached to the head using the insides of a 3-amp block, available in all hardware stores
this is what happened as a result,
We sell Chinese ones, but to what extent are they diamond? the copper tip actually oxidized after an hour of work, that’s what I did with the photo: I somehow didn’t think about it right away because the soldering iron really burns. I replaced the tip with an iron one from a nail (temporarily, with difficulty I pulled out the old one with scale; it couldn’t fall out, this is about the issue of falling out) I tried to burn out small text, I can’t even speak and so everything is visible, the height of the letters is 3 mm, but I’m thinking of just burning it out You can try it with diamond.
In relays and contactors, the silver in the contacts is impure and impregnates the base with something like ceramics or sand, I don’t know for sure, there is not enough of it, if you take a few I think it will be enough for a drop, but for such purposes I don’t think cleanliness is so important that it won’t burn, then for faster heating and maintain a stable temperature, wrap the device on top of the thread with a heat-insulating thread, for example, asbestos thread. B By the way, to control the temperature you can use a simple Chinese multimeter with a thermometer, I don’t remember the model, I think 830, but there the sensor works up to a temperature of 1300 degrees and the wires to it are heat-resistant. Today I bought a diamond Chinese glass cutter, the insert in it is made of brass, I tried it out of interest and put the insert on the burner, the result is the same, it burns out) Tomorrow I will deal with the scale, I will lower the temperature and experiment in general) Yes, about the stripes, I burn out the photos due to the small amount of plywood 8x8 or 6x6 cm, whatever you need, and if you look at them, you can see the stripes, but on a large one, there probably won’t be anything, in general, I’ll try. Or he can use the experience of making a disposable tip for a soldering iron, the point is that the copper tip is coated with a substance (liquid glass + quartz sand from fuses (talc can be used), until it becomes sour cream), then dried, then a spiral is wound onto the coating, then everything is wrapped with glass fiber and that’s it, the heater is ready. I did this with a soldering iron 3-4 years ago, it works and works sometimes for days. Pros: Instead of ceramics from the resistor, coating is on the tip itself. Minus the disposable sting.
Next version: I took a ceramic carrier from a lighter with a spiral, heated it up to 1000 degrees, everything was ok! I inserted a 3 mm diameter rod inside, ground into a cone and polished from contact silver, put 4 turns of 0.8 mm nichrome on top, wound it on a mandrel, then inserted ceramics into it, fastened it in the same way as the old one, everything sits quite rigidly, cold and hot, here is a photo:
Also, I redid the burner circuit off-topic and just put it in a pile, the trance from the burner wound up the secondary a little, raised the voltage to 3 volts, removed the factory wire rheostat in the primary circuit because it was heating up because of this the voltage was low, installed a regulator on a triac from a burnt-out vacuum cleaner, and got the output is stable adjustment from 0 to 3 volts. The head heats up to, say, 479 degrees per minute, when in contact with wood the temperature does not drop, it takes a long time to cool down, I got burned wrapping asbestos (I wrapped it with a 2 mm cord on top), the whole structure holds the load and with the electromagnet when it drops when turned off, it doesn’t move. Tomorrow I'll burn it on new plywood and post a photo. I’m answering the question (if any) why I refused the diamond, it’s a little thick, you can’t sharpen it, and I brought out the rod as I needed. Just wondering, has anyone burned out small text 3mm high, did it work? or unrealistic, I don’t set it as an end in itself, it’s just interesting. I had to abandon asbestos due to its disintegration when heated, I wrote the text with an artcam and turned on raising the head with a magnet, asbestos began to fall onto the workpiece due to vibration, not all of it, of course, but there is some. I'll try to coat it with silicate and sand as suggested above. here is a photo of samples of working with artkam, (if the time after lowering the head is reduced, you can write small things, the letters at the top are 3 mm)
then combined 2 ideas into one,
I tried coating it with sand and silicate and it didn’t work out well, I decided to soak it in asbestos and wrapped it around it, dried it by turning on the heater for at least 30 minutes, then added temperature, it worked.
The coating is durable, relatively sure, but don’t jump on it. here are the final photos,
I burned out the head above in the post, the stripes and dots in the photo are my jambs (I adjusted the heating and did not work in Photoshop) the head behaves normally,
But that is another story. Let's see how long this modification will last

Wood burner diagram.
The wood burner is assembled using a simple dimmer circuit, the load of which includes a step-down transformer 220/4 volts .
In principle, you can buy a regular dimmer - a regulator for incandescent lamps for indoor lighting. Its diagram is identical to the one shown here.
The transformer was taken from the original old ELM burner - 220/4 volts. However, you can use a similar transformer or wind it yourself, using a wire about 1.5 mm in diameter for the secondary winding. Select the number of turns experimentally so that the output is 4 volts.
Installation is carried out using a hinged method, without the use of any board. A power switch and a variable resistor for adjusting power (in our case, the temperature of the burner tip) are attached to the front panel of a homemade burner The installation is actually done at the switch and variable resistor terminals.
The triac is installed on a minimal radiator.
How to make a wood burner with your own hands - a homemade pyrograph from a soldering iron
Have you ever wanted to capture a beautiful design or pattern in your wood crafts? Do you have an old, unused (but still working) soldering iron? So you're in luck. This tutorial will teach you how to make your own wood burner and how to turn ordinary nails into versatile, easy-to-use pyrography (wood burning) tools. This project is also great for those who want to learn how to make fires but don't know where to start.
We use an old soldering iron tip as a template when making new pyrography tools, but of a shortened length to reduce heating time.
Features and types of equipment for wood burning
A transformer for a simple burner, which is used for domestic purposes, that is, not in production, for entertainment, as a hobby, has minimal power and voltage ratings. The voltage values should not be less than 5 Volts, and the current strength should not be 2 Amperes. If the setting shown is less than this threshold, then burning will not work, since the power of the device is not enough to process even soft wood. Many novice fans of the branch of pyrography art are interested in what kind of transformer is needed for a wood burner. Experienced experts agree that it is better to use a reducing type, which has optimal characteristics.
The cord through which electricity is supplied to power the equipment is connected to the nozzles. Various types of filaments are used as the latter. Craftsmen give them a special shape, which is used to create drawings on wood. Instruments that are assembled independently are re-equipped. Instead of a rheostat, a step-down transformer is installed.
If you make a transformer for a wood burner yourself, then replacing a factory transformer is a common thing. The step-down device allows you to control the voltage of the filament and set the voltage required for operation. The addition also allows you to choose interesting filaments and feathers, with the help of which you can create a pattern of different shades.
Finding the right wood burner is not as easy as it seems at first glance. Available options:
- with wire tip;
- with a hard nib.
The first burner is equipped with a special nichrome wire. It is attached to a fork, which is taken in the hand. The wire heats up instantly, you can start working right away. Modern transformers make it possible to control the process - the heating temperature of the wire is set. Wire options are more convenient for precision work, since the movement of the hand is completely transmitted. The result is high quality work. In turn, burners with a pen pen are easy to use for beginners. They heat up and cool down quickly and do not cause errors. It will not be possible to perform ultra-precise work, since the pen has limited length and diameter. The pen is attached to a special attachment, which is screwed to the handle with small bolts.
Design and principle of operation of a wood burner
The device of a pyrograph is generally very simple. A piece of nichrome wire is attached to a wooden handle, to which electrical voltage is supplied. Under the influence of current, nichrome heats up to a temperature of about 1000 degrees. If you run a hot tip over the surface of a board or plywood, it leaves a scorched mark, just as a pen leaves an ink mark.
Next, we consider the manufacture of a pyrograph powered by a voltage of 5 V from a computer power supply.
How to make a wood burner with your own hands: useful tips
Any work at home, especially that which concerns the manufacture of electrical appliances, begins with careful preparation. It is necessary not only to carefully study the electrical circuits and plan the sequence of actions, but also to prepare in advance the basic materials and improvised devices that will be useful in the process of creating an electric burner. If this is your first time dealing with such work, it would be a good idea to watch training videos on YouTube to better understand what you have to deal with.
Now let's take a closer look at how to make the simplest burner with your own hands. First, you will need to decide on the tasks and select the necessary components for the job. If you need a simple burner, it will be enough to use a power supply or battery, as well as nichrome wire or a medical needle. To make a powerful soldering station for burning, you will need to find or make a separate transformer unit at home, and also use a thermostat (as an option, a dimmer for light bulbs is suitable).
In this article we will look at popular options for the simplest pyrographs, the manufacture of which does not require special skills and knowledge. You can use a smartphone charger or a battery from a screwdriver as a step-down transformer. The optimal characteristics are 5 V and 2 A. If you charge less power, the working tool of the device is unlikely to be able to heat up to the desired temperature. Additionally, you will need needles (sewing or medical) and terminals, as well as consumables: strong threads, superglue, flux and solder.
