DIY wood burning machine. How to make a homemade and simple mini burner. Operation of the wood burner circuit and its settings
A portable electronic burner is a device for applying a design to a certain type of material (wood, cardboard, paper, plywood, fabric). The product is widely used in the field of amateur pyrography, therefore this device It is very popular not only among professional artists, but also among private fans of painting paintings.
To make a homemade burner with your own hands you will need minimum set components and tools that can be used from household items or purchased at your local hardware store.
Preparation of materials for manufacturing
To make a home burner you need to have a minimum set of tools and components.
To make a pyrograph you will need:
- Wooden glazing bead 10 cm.
- Adhesive tape or electrical tape.
- The electronic unit is no less than 5 Volt 2A.
- Nichrome thread.
- Soldering iron.
- Electric drill with suitable drill.
- Flux for soldering.
- Solder is tin.
The manufacturing process begins with the preparation of all tools and necessary materials. First you need to find a nichrome thread, which can be sold at any hardware store. If there is no thread on sale, the material can be obtained from an old electric soldering iron.
You will need to disassemble the heating part of the electrical appliance. The nichrome thread is located on the “tip” of the soldering iron under a metal casing and is easily removed by winding without the use of third-party tools.
How to make a mini burner?
1. Making a holder into which the burning needle is inserted.
The holder can be made from an ordinary wooden glazing bead, the length of which can be selected individually. On average, 10 sentiments are enough. You will need to make a hole inside the handle for the wire. The procedure can be carried out using an electric drill or screwdriver.
The drill should be selected strictly according to the thickness of the wire. At the end of the bead it is necessary to make a small extension for the terminals of the ends of the wires to which the needle will be attached nichrome wire.
2. Connecting the electronic unit to the needle
A homemade burner operates from a 5 Volt electronic unit with a power of at least 2 Amps. A regular phone charger with the required characteristics will be suitable as an electrical unit. To connect, make a branch of the two-core wire, divide it into 2 separate ones. The ends are passed through a previously made hole in the handle and brought out.
3. Soldering the needle to the wires
A nichrome needle must be soldered at the ends to the lead-out wires. Each separate end is soldered to a separate wire. For solder, you should use flux, since the nichrome material is quite difficult to solder. The needle size must be at least 5 centimeters, otherwise the burner will not heat the thread sufficiently and its performance will accordingly deteriorate.
4. Insulate the holder with electrical tape
You can make insulation using electrical tape or adhesive tape. The burner holder is wrapped in 3-5 layers and pressed tightly in your hands so that the tape sticks to the surface as efficiently as possible. wooden base. During gluing, avoid getting electrical tape on the needle.
5. Testing the burner
To test the burner, you need to connect the electronic unit to a 220 Volt network, after which you can observe the redness of the needle thread within a few seconds. The device should be tested on any wooden surface.

How to make a homemade and simple mini burner
The art of wood burning is a hobby for many people of different ages and flooring, so in this article we’ll look at how to make a simple mini burner for woodworking. This tool has proven itself well.
To make a mini-burner we need a soldering iron, an old unnecessary power supply from mobile phone or from a charger for a screwdriver. It's better that it was powerful block nutrition as much as possible. For example, a power supply from an iPhone for 5.1 volts and 2 Amperes is well suited for our craft. You will also need a barbecue skewer, three needles, two of which are from a syringe and another one, for example, a sewing needle. You also need threads, flux and solder.
First, we must bite off the nose of the syringe needle, since we will not use it. You can do this using round nose pliers or pliers. The next thing to do is to attach two needles to the BBQ skewer using threads. This should be done in such a way that they are positioned parallel to each other. Now you need to bend the end of the sewing needle so that it just barely touches the tip of the syringe needle. Next we must solder the wires from the power supply to the needles, in this case the polarity does not matter. Apply a little flux and tin the joints. We must solder the first wire, and then the second. Then attach the wires to the skewers using thread, cut off the excess end of the wooden skewer.
We can say that the burning tool is almost ready. To make it more secure, you can also soak the threads in superglue and then apply heat shrink tubing.
The mini-burner is ready and it works very easily. When current is applied, the needle from the syringe begins to heat up, this happens because it has thin walls. Now we can test our tool. The game heats up even though the power supply only has 2 Amps and 5.1 Volts. This excellent result, as you may have already noticed, despite its small size, this device shows excellent results. It is quite possible to make a hole in wooden slats up to 1 cm in thickness.
Happy crafting!

How does a wood burner circuit work?
A DIY wood burner usually consists of a fuse, a dinistor, a step-down transformer and other components. What skills do you need to master the circuit setup? Have the desire, be able to solder and be careful when connecting all the components together.
Features of the process are described by the following points:
- It is necessary to control the operation of the output voltage from transformer TP1, focusing on the primary winding, and do not let this factor confuse you. The equipment is based on a power regulator circuit for a soldering iron, which is why it does not matter what shape and quality the sinusoids have.
- Also emphasize that the winding made in the second circle must withstand the current flowing to the nichrome wire. Calculate its values yourself, based on Ohm’s law.
- Wires adjacent to the equipment lever must be properly insulated. Safety precautions when working with electricity are very important, therefore, when making a wood burner with your own hands, take this detail into account.
How to make a wire holder built into the burner
If you have ever assembled a power supply for equipment, installing a wood burner will not be difficult. An additional question that will arise during the first use is what to make the holder from? The handle should be functional and at the same time comfortable so that you can hold the device in your hand.
So, arm yourself with these elements:
- a handle from an old soldering tool;
- a piece of textolite; as an option, carbolite or other dielectric material resistant to high temperatures is suitable;
- electrical tape;
- nichrome wire (if this is not available, it is not necessary to buy a new coil, you can replace it with an incandescent spiral in an electric oven, or rather, bite off the tip from it);
- terminals for electrical installation.
Step-by-step instructions on how to make a holder look like this:
- Remove the wiring terminals from insulating material and fix it to the PCB by winding.
- You can add strength and reliability by using a plastic or thread clamp. Threads should be used to connect the cable and the textolite area to the terminals. To prevent the wires from dangling haphazardly, carefully treat them with a heated soldering iron.
- Finally, press the wire into place in the wooden handle.

The second method of making a wood burner
To make a wood burner in another way, you need to collect the following list of materials:
- 12 Volt car battery. If there is electricity in the room, instead of a battery, it is enough to use a cord equipped with a plug at the end, which is inserted into an outlet in the wall and “pumps” current.
- A piece of electrical tape.
- Small slats for a future handle.
- Clamps from a failed relay designed for 220 Volts.
- 2 wires made of aluminum, which are already treated with insulation, a diameter of 2 mm is quite enough.
- Thick cable suitable for the output.
- A spiral designed for burning wood, perfect option– thickness 0.7 mm.
Assembly process in the second way
You can make a wood burner, keeping in mind that the tip connected to 12 Volts burns out quickly, so to prevent this, you need to reduce the temperature. How can I do that? Equip a rheostat from a spiral part.
The rheostat is located on top of the screwdriver in a circle, and then connected like a spring to the battery. Make sure that the connection is reliable and strong - the operation of the tool largely depends on this.
What to do next
- Take one end of the wire that comes from the equipment in your hand and connect it to the battery. At this time, place the remaining end near the rheostat.
- It is easy to turn on the wood burner by fixing the rheostat to the 2nd terminal related to the battery. To prevent the rheostat from moving and remaining stable, secure its position with a clothespin.
- Next, screw the spiral part to the relay using bolts.
- Connect the cables that run along the wooden handle to the relay.
- Wrap the entire product with electrical tape.
- A two-core wire is fixed to the wiring, one end of which is connected to the battery, and the other goes into the rheostat.
- There is no battery nearby - use another voltage source, which one is not so important.

How to make a wood burner with your own hands? Scheme of a homemade wood burner
Pyrography is one of the techniques for applying images to hard surfaces made of organic materials using heated to high temperatures subject. Wood is mainly used as the basis for the painting. The burning tool is a loop of nichrome wire fixed in a special holder. You can make a wood burner with your own hands different ways and even provide software control devices.
However, such a scheme is quite complex, and its implementation will require inaccessible broad masses equipment. However, you can make a fairly simple burner with your own hands, literally from scrap materials and a power supply. It has a step-down transformer and a simple circuit electrical diagram control of currents on the primary circuit.
Operating principle of the pyrograph
Two questions arise at once: how to make a wood burner and how does it all work? In order to understand this, it is necessary to understand the physical principles. In general, the device works as follows: a heating element made of nichrome wire heats up alternating current up to high temperatures. When it comes into contact with a smooth wooden surface, it becomes charred.
The degree of impact on the material can be adjusted by varying the contact time, its force and current parameters. The first two indicators are determined by eye by changing the color of the plate. The current is adjusted using a variable resistor installed on the device body. Experienced craftsmen pyrographers select the current once at the beginning of work on the image, and then only control the holder.
Materials and components for a homemade burner
Classic wood burner design industrial production difficult to implement in artisanal conditions. It was modernized by folk craftsmen, and as a result, current control was transferred from the output of the secondary to the input of the primary winding. This is how an adjustable soldering iron works. For a fairly crude heating element, which is essentially a piece of nichrome wire, the shape of the output voltage is not particularly important.
Much more important is the ability to more or less accurately adjust and stabilize the voltage. It is easier to achieve the required indicators by varying the indicators of the primary circuit. Special meaning has a wire cross-section in the secondary winding - it must be sufficient to withstand the current load on the heating element. Values are calculated using the formula where resistance is equal to the ratio of voltage to current (Ohm's law).
Making a holder for a pyrograph
It is based on a handle made of durable dielectric material. This could be a ready-made soldering iron handle made of wood or heat-resistant polymer. Voltage is supplied to the tool via a two-core electrical wire with double insulation of the PVA type. The cross-section of the conductor must be at least 1 sq. mm, which is quite enough to ensure safe work masters of pyrography.
A do-it-yourself burner is made in such a way as to eliminate the possibility of electric shock to a person. Important detail– a holder for a nichrome heater, which is nothing more than a piece of an incandescent coil for an electric stove open type. It is fixed on a board made of PCB or other material resistant to high temperatures.
The best fastenings for the filament element are electrical terminals with fixing screws. They are removed from the plastic case and attached to the insulator. On one side, a power wire is inserted into them, passed through the handle, and on the other side, a nichrome heating element. After assembly, the plate is carefully inserted into the cavity of the handle and secured there.
Assembling and setting up the pyrograph
A homemade wood burner consists of a power supply and a holder with a heating element. It is connected to the secondary winding of the step-down transformer. For this purpose, standard screw wiring terminals installed on the board are used. The primary circuit of the transformer is controlled by a simple electrical circuit of three resistances, as many capacitors and two triodes.
Do-it-yourself wood burner is mounted in a plastic or metal case. Can be used to assemble the control circuit printed circuit board or produced the so-called wall-mounted installation. After assembly, the device is connected and configured. It comes down to checking the voltage regulation limits at the output of the secondary winding; they should fall within the range from 3 to 8 V.
Intended use of the device
A DIY wood burner is used to create paintings and other images. The procedure for working with it is as follows: the photograph is transferred from paper to the prepared surface using ordinary carbon paper. Then, using a well-heated device, lines, strokes and dots are applied, which will create a complete image.
Conclusion
Wood burner, made with your own hands from available materials, will be an excellent tool for creative development personality. This activity is equally exciting for both adults and children. The growth of the artist’s skill occurs during the development and consolidation of the skill of working with the device.
Not only many teenagers, but also adults enjoy wood burning. Wood makes beautiful souvenirs that can be given as gifts. New Year, birthday or just any memorable date. Are in particular demand wooden boards with a drawing that you make yourself.
We suggest watching a video that will help you make a wood burner at home.
For a wood burner we will need:
- a 12-volt car battery, but if there is electricity in the room, then the battery can simply be replaced with a cord with a plug that will connect to the network;
- electrical tape;
- small boards for pens;
- fastenings from an old 220 volt relay;
- 2 aluminum wires with insulation, approximately 2 mm in diameter;
- a thick wire connected to the output;
- spiral for burning, 0.7 mm thick.
I would like to immediately note that at 12 volts the tip burns out very quickly and in order to prevent it from burning out, we simply lower the temperature. The easiest way is to make a rheostat from the same spiral.
We wrap the rheostat around a screwdriver like a spring and simply connect it to the battery. Be sure to make a reliable connection.
We connect one end of the cable that comes from the burner to the battery, and the other end to the rheostat.
To turn on the burning device, we connect a rheostat to the second terminal of the battery. Be sure to attach the rheostat with a clothespin.
We attach wires to the relay that will run along wooden handle. We wrap the entire structure with electrical tape. We attach a two-core cable to the wiring, one end of which will go to the battery, and the other to the rheostat.
Many people today, both adults and children, love wood burning. This hobby option even has its own name - pyrography. This type of art appeared quite a long time ago, and its essence lies in depicting drawings on hard surfaces of wood so as to capture the picture for a long time. To do this, you need a heated object that can melt the surface and leave marks.
What materials are needed? Wood is suitable as a base for the future image, since this material is one of the most inexpensive and amenable to burning.
Undoubtedly, every person has seen the result of pyrography at least once in his life. This word is translated as “image using fire.” The drawings look really very original.
Like drawing, wood burning is quite a voluminous and painstaking work. To create a masterpiece of pyrography, it is not enough to depict an element or someone's face. It is necessary to convey every touch, even the most insignificant, reflecting the expression of the eyes and mood.
How to make a burner yourself?
To create a burner with your own hands, you will need quick wits and perseverance, since this is not the easiest thing to do, and the diagram is quite confusing. During production, you will have to use different equipment that is not commercially available.
What do we need?
The list of necessary items depends on what kind of wood burner you want to make. The only thing you will need in any case is nichrome thread. The next required spare parts are a wire and a battery. It's good if the battery is rechargeable, because Full time job The device will consume a lot of regular batteries - this will hit your pocket.
There are also some requirements for the wire. Good wire will be the key to your safety, so approach the issue with all responsibility.
Where can I get the diagram?
You can develop the scheme yourself. We also present in the article several different schemes– from elementary to complex. All inventions were calculated according to the developer’s requirements, and you can choose the appropriate option.
It should be noted that each person is individual and has his own character and requirements. There are a lot of options for schemes, so you can try to make your own, even if it is more complex and demanding than those presented.
Of course, it will be easier to implement your own scheme for those people who are familiar with the laws of physics and who have encountered electrical circuits. If you don’t understand this, find information and images of circuits, understand them and find out what works and how.
Where to begin?
You should always start by modeling the burner in your head, and then you need to transfer the drawing to paper. Once you have clear ideas, you can start looking for components. This will take a little time, since the basic parts are available in almost any home. If you need a pyrograph with interchangeable nozzles and temperature changes, things get more complicated.
How to make a simple burner?
Few people have enough time to create a complex burner, so let's consider a simple option.
Materials
To assemble this device you will need the following:
- sewing needle;
- needle from a medical syringe;
- double wire.
The needle is very important as its quality will affect the quality of your masterpieces. It is better to choose a thin and sharp needle. The needle from the syringe will heat up to red during operation, and the sewing needle will lightly touch it - this will cause resistance and help warm up the needle.
Build process
To make a burner you will need a cap from syringe needle and a sewing needle and thread. You need to pierce the cap with a needle and pull the thread to the end so that the needle rests on the cap. To secure it, wrap it with the rest of the thread, and the needle should go beyond the cap and be placed parallel to it.
Let's return to the syringe part. We don't need the cone-shaped cap - we remove it. We wind the needle to the opposite part of the cap with another thread and a sewing needle. Now slightly bend the tip of the needle so that its tip barely touches the sewing needle. As we said, than smaller area contact, the faster the burner will heat up.
Nutrition
We take a good double wire - it should be stripped on both sides and two holes should be made in the cap to bring the wire out. After this, connect each wire to the needles - screw them as tightly as possible, since the quality of current flow will depend on this.
For quality and safety, finally secure the wire with electrical tape.
Finally, use an unnecessary button, for example, from an old tape recorder, and a battery. The main thing is not to reverse the polarity, otherwise the device will not warm up.
Let's sum it up
It should be noted that burning today is not just a hobby, but can become a way to earn money. Every day the demand for burning landscapes and portraits is increasing - this activity competes with wood carving. Initially, it was created to diversify the interiors of ancient houses of the 19-20 centuries. When you couldn't buy it in stores beautiful furniture, it had to be created with your own hands.
In fact, you can make any type of wood burner in as soon as possible. A drawn drawing or sketch will simplify the assembly process and creation of the device.
It doesn't matter how complex your device is - the main thing is to make the tip correctly. The quality of all created paintings depends on it. If the burner draws patterns on wood as accurately as possible, you will be able to draw images of any complexity.
The device has two operating modes. In the first position of the switch " norm"(I), it operates at half power: approximately 30-35W. In the second " turbo"(II) - 65-70W. The yellow LED shines in both modes, red only in the second. Indication LEDs are any, not bright ( AL307).
In order to make an electric burner you will need a cheap ($2-2.5) switching power supply (UPS) made in China, at 50-60 W, for halogen lamps. You can find them in stores around furniture fittings or in hardware stores.
Burner circuit
Schematic diagram of an electric burner based on ET
On the Internet, I came across a modification for making a pulse soldering iron. In the case of a burner, minimal modifications to the UPS will be required.
First, remove the board from the case and solder the output transformer. A lot has been written about these schemes, so I won’t go into details. It copes well as an electric burner. I'll just say that bipolar transistors MJE13003 (TUVE13007) can be replaced with more powerful current ones - MJE13005, MJE13007(last digit means operating current). At choosing a UPS, you need to take into account the fact that it should not have protection from short circuit!
So, having removed the transformer from the board, it must be disassembled. A lot has also been written about disassembling ferromagnetic transformers. But, I will share my experience. First of all, remove the film and use a knife to remove the glue on the core connection. Afterwards, heat the water in a small container until it boils. But we don’t immediately throw it into boiling water, but heat it first warm water. Due to the fact that the quality of these trances is very low, they can break. Therefore, after warming it up a little, we put it in boiling water and leave it there for a few seconds. The procedure can be repeated and try to loosen the winding body, and also run a knife along the seams of the ferrite halves. In the end, you will be able to disassemble it, but do not rush, do everything with caution. In my case, even after breaking such a trance, I did not despair, and connected the four pieces of the core with tape. Some glue the cracked slices, but even without that it works just fine, tightly compressed with adhesive tape.
Having disassembled the transformer, remove the secondary winding, and in its place we wind 3-4 turns stranded wire, cross section 2.5-4mm2. Suitable for this electrical cable(network). The insulation is first removed, and in its place a heat-shrinkable casing of suitable size is put on. Why heat shrink tubing? Because she takes less space, regarding cable insulation. Now, we wind four turns, with a branch from the third. The voltage on the last turn will be approximately 9.0-10.5V. All that remains is to put the transformer back together and remove the leads, as can be seen in the photographs.
It's time to work on the body of the electric burner. For this we need an aluminum furniture leg. Yes, yes, furniture again! It is very cheap (less than a dollar), but most importantly it is made of 1 mm thick aluminum. Thus, the case will serve as a heat sink for transistors, which get very hot. Square leg height =100mm. The issue of the front panel is also resolved. To do this, we disassemble the leg and leave a plastic plug with which we cut off a part - so that all the components of the product fit. Further, the radiator for transistor switches is also aluminum.
I used a 5mm thick plate radiator. It already had threaded holes, which I later used. But if you find a copper plate, it will definitely serve as a better heat sink. You can also use any other radiator of a suitable size. In addition to this radiator, I connected an aluminum U-shaped profile - you guessed it, also a furniture one, which fits tightly into the square profile of the case.
The radiator must be in close contact with the body! This way, the heat will be distributed evenly, with greater efficiency, throughout the entire body, without requiring bulky radiators. The U-shaped profile is connected to the radiator plate with a small gap (2-3 mm) through small washers and then we screw this “sandwich” to the plate included in the impulse generator kit. Transistors and the board must be attached through an insulator, also from the UPS. It is preferable to ground the burner body.
Don't forget, the device is connected to mains voltage at 220V, so we take all safety measures during assembly and commissioning!
Now, we drill holes in the plastic front panel for the electric burner operating mode switch - for wires and for LEDs red And yellow glow. We connect the LEDs with limiting resistors with hot glue, as can be seen in the photo.
Next, twist the switch and solder all the wires together (see figure). Switch – P2T-21(Soviet production, maximum switching power up to 660 W at active load). It is necessary to use the most powerful toggle switch possible, otherwise the contacts will overheat! Maximum power electric burner reaches 70 watts.
To the body, as legs (anti-slip), we glue self-adhesive cork or silicone (available from glaziers and furniture makers). As a handle, I used a ready-made handle from a burner industrial production. And if you make it yourself, then a handle from a burnt soldering iron will do. Or we cut it out of textolite, wood with a fluoroplastic tip of suitable thickness. Fastening for nichrome - the terminals of electrical blocks are just suitable for these purposes.
I found nichrome for tips with a diameter of 0.8-1.5 mm on the radio market. Suitable for different heating devices. It must be bent as in the photographs and the tip flattened with a hammer. I made two types of tips: one from millimeter nichrome - for burning and cutting, the other from one and a half millimeter, for more rough work. Accordingly, the second one will effectively heat in a more powerful operating mode of the device (turbo).
The wire for the electric burner must be selected with a large cross-section and the most flexible. Otherwise it will get warm. Naturally, the electric burner will work intermittently, approximately 15-30 minutes.
Firstly, the efficiency is very low, which leads to large heat losses. And secondly, the handle will heat up, which forces you to work with it cyclically. For more convenient use, I advise you to adapt a push-button pedal (from sewing machine or from some machine) or a push-button power switch, etc. I did not make additional holes in the case or radiator for heat removal. This is at your discretion, depending on the radiator used.
The device is very easy to manufacture, thanks to ready-made solutions to assemble it. It can be made by any beginner with minimal electronics skills. The main thing is to follow safety rules when working with it. After all, the tip temperature reaches 500-600 degrees.
If you make an electric burner for a child, then the presence of an adult when working with it is mandatory. I hope it brings joy and creative success! ).
Discuss the article ELECTRIC BURNER
- Preparatory work
- Build process
Pyrography, or wood burning, is a fascinating and interesting hobby. It is mastered by those who love visual arts. Writings that first mention fire-scorched patterns date back to 700 BC. e. The burning apparatus was invented at the beginning of the 20th century. The first devices were made from a glass container supplemented with two rubber tubes. At the end of one of the tubes a rubber ball was attached to pump air, at the end of the other there was a platinum tip connected to the handle.
In the middle of the 20th century, a new type of electric burner appeared, which became the prototype modern apparatus. Distinctive look applied arts became available to children.
The design has undergone considerable changes since then. Manufacturers install a power regulator. With its help, you can smoothly adjust the temperature of the working needle. This allows you to apply a pattern to any available material. On sale you can find models with big amount nozzles Thanks to different-sized pens, it is possible to create strokes different sizes, give the drawing volume.
Despite the sufficient choice among factory-made devices, many craftsmen want to make a wood burner with their own hands. This is mostly used by experienced artists..
Problems are often discovered with the built-in transformer, and you have to solve the problem yourself.
Some craftsmen want to supplement their existing simple burner with a special device with which you can adjust the degree of heating of the needle. The article provided practical guide on assembling a mini wood burner using improvised materials.
Electrical circuit development
During assembly homemade burner It is necessary to have knowledge in the field of radio electronics. This will allow you to develop an electrical circuit. If you do not have skills in this area, you can use the diagram presented below.
The circuit can be simple or quite complex, tailored to the developer’s requirements. The task is to select the most acceptable option and implement it in practice.
Preparatory work
Before making a burner, you need to plan the process, assemble necessary materials, devices. The set of components depends on what type of device you plan to make. If you need a burner with temperature control, you will have to find a dimmer, dimmer, or a mechanism similar in functionality. You also need to prepare:
- sewing needle;
- needle removable from the syringe;
- power unit;
- soldering device.
To work, you need to take an old mobile phone charger. For a homemade burner, a power supply from an iPhone works well. Its output voltage is 5.1 V and 2 A. H The more powerful the charger or battery pack is, the better . If there is no such device, you can use a charger for a screwdriver or other similar compact tool that does not work or is not used because it is not needed. You also need to find a barbecue skewer, high-strength threads, flux, and solder on the farm or buy in a store.
A needle is one of the main elements of a homemade wood burner. Her choice should be approached responsibly. It is this detail that determines how refined the ornament will be, the miniature silhouette applied to wooden surface. Recommendedgive preference to a thin and sharp needle. A good option- medical needle. She will get hot maximum temperature, evenly heat the sewing needle, which will burn the pattern onto the material being processed.
Build process
First you need to take round pliers or metalwork pliers. With their help, the tip of a medical needle is bitten off. Then, strictly parallel, two needles are attached to a barbecue skewer and secured with a strong thread. The end of the sewing needle is carefully bent until it lightly touches the tip of the medical needle.
Then you need to connect the wires from charger to the needles. Polarity does not matter; wires can be connected as desired.
In order for the electric burner to serve for a long time and reliably, the connection points must be properly processed. To do this, a small amount of floss is applied to them, then they are tinned.
The wires for the burner are soldered one at a time, attached to wooden skewers, and secured with threads. The excess protruding ends of the skewers are cut off. For greater reliability, the threads can be treated with superglue to protect heat shrink tube. After this stage, the device is ready and can be used for its intended purpose.
The figure shows an example of a burner.
The principle of operation of the device does not differ from the principle of operation of the factory device. Despite the fact that charging has only 2 A and 5.1 V, at the moment of application electric current The thin-walled hollow needle from the syringe heats up intensely and transfers heat to the sewing needle. The burner is compact, shows excellent performance in practice, and allows you to apply 10 mm thick strokes to a wooden surface.
To better understand the assembly process, you can watch the video.
