How many microphones and capacitors are there for a self-sounding machine? Do-it-yourself brewing machine using capacitors

20.06.2023

I bought my own automatic transformer. Well, I was thinking of wearing it out for a long time, because I planned it for welding and car body repair. As a result, I was disappointed that the thin metal was simply spat at the moment of striking the welding dart on the surface that was being cooked. And the thick metal is about 4 mm thin, simply not boiled like a trace.

Finally, I just wanted to throw him out. You can’t carry it back to the store, since a lot of hours have passed, and I have more than one robot. Axis I decided to select an inverter for my device in order to use a transformer that did not understand how.

The scheme itself is of little help. This circuit was taken from the basis of a 250 ampere welding inverter, designed by Evgen Rodikov. For what you dyakuyu.

True, I had a chance to tinker a little with this circuit, so that the initial welding inverter of some kind of current-voltage characteristic (volt-ampere characteristic) became tight and so that there was a return connection for the voltage and could be regulated from 7 volts up to 25 volts. Since on an automatic machine there is no need to adjust the struts, you need to change the voltage. What was spoiled by me.

To begin with, we need to collect a life block, a live generator and key drivers.

The axis is in charge and the scheme of the living block is not complicated and I think I won’t go into details and so everything is clear.

Operating principle of the inverter

The work of the inverter is why. Between 220 volts go to one place and then it is rectified to charge high-capacity capacitors through the flow-coupling resistor R11. If it’s not a resistor, then there would be a strong bang, which would result in one place going wrong . When the capacitors are charged, the timer VT1, C6, R9, VD7 turns on relay K1, thereby shunting the flow-intermitting resistor R11 and the voltage at this hour on the capacitors increases to 310 volts. And at the same time, relay K2 turns on, which opens the resistor R10, which blocks the operation of the PWM generator, assembled on the UC3845 microcircuit. The signal from the 6th leg of the PWM generator goes to the optocoupler through resistors R12, R13. Then passing through the HCPL3120 optocouplers to the drivers, they control the IGBT power transistors, which trigger the power transformer. After the transformer, a great high-frequency stream comes out and goes to the diode, thereby straightening itself. Monitoring the voltage and power supply on the PC817 optocoupler and flow sensor, impulses on the ferite ring, through any missing wire of the power transformer.

The beginning of the inverter robot assembly

The collection itself can be started as soon as possible. I especially started to remove the life block itself, which is responsible for the life of the generator and key driver. Having verified the usefulness of the life block, it started working for me without any further examination or adjustment. At the next stage, having selected a timer that is responsible for blocking the generator and shunting the flow-intermitting resistor R11, having switched to its robot, it is responsible for turning on relays K1 and K2 for an hour from 5 to 15 seconds. If the timer demands more speed, it is necessary to increase the capacitance of capacitor C6. After which I started the folded generator and the power switch driver in our generator, and one shortcoming with resistors R7 is to blame for the mother of the 680 Ohm R8 1.8 Ohm and the capacitor C5 510p C3 2200p, also changing to the correct selection setting the cob frequency to 50 R1. In this case, the signal generated by our generator is due to being strictly rectangular 50/50 and the daily splashes and drops from the edges of the rectangular displays on the oscillograms of the oscillograph. After I removed the power switches and applied minus 310 volts to the lower power switches. plus the upper power switches, I supplied power plus 310 volts through a light bulb 220 volts 200 watts on the diagram itself is not shown, except for the need to supply power switches plus and minus 310 volts, add capacitors 0.15 µF x 1000 volts 14 pieces. This is necessary in order to ensure that any transformer that will be created goes into the life of the power switches that will easily pass into the 220 volt range. Why did I start assembling a power transformer, but it all started like this for me. I don’t know what kind of ferrite material I wound a test winding on the butt of 12 turns from a copper core 0.7 mm in diameter, coated with varnish, weaving it between the shoulders of the power switches and running the circuit until it reconnected, so that the light bulb burns under the voltage of the three having checked approximately 5 or 10 hvilins by connecting the diagram Letting the filtering capacitors discharge so that the flow does not hit the core of the power transducer itself should not heat up. As soon as the number of windings became heated, I increased the number of windings to 18 turns. And so I wound the transformer with a series of cuts, as written on the diagram.

Setup and first launch of the inverter

Before adjustments and first start-up, we check once again with the correct selection. We need to change the correct phase of the power transformer and the sensor flow on a small ring. The flow sensor depends on the number of turns of the drill, the more turns the larger the output flow, otherwise it is not possible to miss through those that can override the power keys and the smell can easily go wrong. In this case, if you do not know the ferrite material, it is best to start with 67 turns and gradually increase the number of turns to a sufficient arc strength during welding. For example, I ended up with 80 turns, which means I don’t have tension in the fence, the power switches don’t get hot, and there’s naturally no noise coming from the power transformer and the output choke.

And so begins the first start-up and adjustment when the light bulb is turned on, as described above with a combination of capacitors with 14 pieces of 0.15 µF each due to the fact that it is necessary to turn on the keys plus and minus 310 volts. turn on the oscilloscope on the emitter and the collector of the lower arm of the power switches. Before we do this, we do not connect the optocoupler of the gate connection to the voltage, while the forward-cut frequency signal may be visible on the oscillograph, we take a twist and twist the resistor R1 until a small bend appears on the lower edge of the straight-cut. Turn the frequency change. We will talk about oversaturation of the power transformer core. When bending the selected frequency, record it and adjust the operating frequency of the power transformer core. For example, the oversaturation frequency of 30 kHz is important, so 30 is divided by 2, subtracting 15, subtracting the number to add to the oversaturation frequency of 30 plus 15, subtracting 45. 45 kHz is our operating frequency. In this case, the light bulb must glow in the darkest darkness. The flow rate may be increased at full idle speed 300 mA, set to 150 mA. Use an oscilloscope to ensure there are no voltage spikes above 400 volts, call 320 volts. Once everything is ready, boil the kettle or heater or sander to the light bulb at 2000 W. As a result, it is necessary to carry out a decent cross-cut, for example, 5 square meters of 2 meters with a very short circuit, in which case the light bulb does not have to burn at full brightness, it has to glow a little more than half of the frying. If it glows with all its brightness, you will need to check the flow sensor at the phaser again, just pass the wire from the other side. At extreme approaches, change the number of turns on the flow sensor. After everything is ready now, plus the life of 310 volts, let it run directly without a light bulb and heat up 2000 volts. Don’t forget about cooling the power switches, a radiator with a fan is best suited for a radiator on an old Intel Pentium or AM Atom computer. The power keys are screwed onto the radiator without a mica gasket and through a thin ball of thermal conductive paste KPT8 to ensure maximum cooling efficiency. The radiator needs to operate directly from the upper and lower shoulders of the platform. Place the supply LEDs and switching LEDs between the mains and the transformer on the same radiators as the switches, and also through a mica gasket to avoid short circuits. All the capacitors on our generator are the same ones with the inscription NPF, so you will not take the moment for weather minds. The capacitors on the snubbers and on the output diodes are strictly of the K78-2 or SVV81 type and should never go there, as the snubber plays an important role in this system and they absorb all the negative energy that creates a power transformation ator.

The start button of the automatic machine, which is located on the sleeve of the coat, needs to be damaged due to overheating of the temperature sensor. in this situation, the voltage required will be no more than 55 volts, which reaches 100 volts, or it is more necessary to change the number of turns, for example, wind up 2 turns, in order to eliminate the voltage we need, after which we can install condenser ator and optocoupler of the gate connection. Resistor R55 is the voltage regulator R56, the maximum voltage exchange resistor is better to be soldered into the board in the order of the optocoupler in order to eliminate the stripping when the regulator is cut off and select it in a larger support until the required maximum voltage is generated, for example, up to 27 volts . Resistor R57 is adjusted for twisting to adjust the minimum voltage, for example, 7 volts.

Disintegrated in the 30s of the twentieth century, the technology of capacitor welding began to expand widely. Tsyomu hid low factors.

Simplicity of the design of the cooking apparatus. You can pick it up with your own hands.
The energy intensity of the work process is noticeably low and there is little need for electrical interference.
High productivity, which is incredibly important when producing serial products.
Reduced thermal flow on materials to be joined. This feature of the technology makes it possible to freeze them when welding small-sized parts, as well as on visible surfaces, where the use of primary methods would inevitably lead to unnecessary deformations of the material.

Once we add that a mother of average qualification is sufficient to apply clear sutures, the reasons for the popularity of this method of contact welding become obvious.

The technology is based on primary contact welding. The difference is that the stream is supplied to the welding electrode not continuously, but appears to be a short and forceful pulse. This impulse is removed by installing high-capacity capacitors. As a result, good indicators of two important parameters can be achieved.

A short hour of thermal heating of the parts to be joined. This feature is successfully exploited by manufacturers of electronic components. Best suited for transformerless installations.
The tightness of the stitch is high, which for the strength of the seam is much more important for its tension. Vikorist and transformer systems must overcome this pressure.

Depending on the selection process, choose one of three technological methods.

The point capacitor is not sealed. A vicoristic and short pulse of the jet, which is ejected by the capacitor, connects the parts in precision machinery, electrovacuum and electronic technology. This technology is also suitable for welding parts that are subject to significant wear and tear.
The roller suture allows you to cut off the sealed joint that is created without any welding points that overlap. This is due to the stagnation of technology in the process of manufacturing electric vacuum, membrane and bellows devices.
Stick cooking can be done in both contact and non-contact ways. In both cases, melting occurs at the place where the parts are joined.

Areas where the technology is used are different, but with particular success, vikorist is used for fastening bushings, studs and other fastenings to sheet metal. Due to the peculiarities of the process, it is necessary to adapt to the needs of the rich variety of plants.

In automobiles, it is necessary to reliably connect body panels made of sheet steel to each other.
Aircraft equipment that hangs special equipment up to the value of welded seams.
The vessel operates in a highly efficient manner, saving energy and wasted materials gives a particularly positive result.
Finding precise adjustments and unacceptable deformations of the parts to be joined.
Budivnitstvo, in which a wide range of structures emerged from sheet metal.

Everywhere it is required simply from the device and awkwardly from the vikoristan ownership. With this help, you can improve the production of serial products or improve your garden plot.

Self-contained capacitor, not sealed

In stores you can get ready to purchase without any problems. But through the simplicity of its design, as well as the low quality and availability of materials, many people are willing to select equipment for capacitor welding with their own hands. Pragnenya will save money wisely, and you can easily identify the required scheme and report description. Proceeds like this in the following manner:

The flow is directed through the primary winding of the live transformer and the other place where it is rectified.
A signal from the thyristor that controls it, equipped with a start button, is supplied to the diagonal of the bridge.
The thyristor has a capacitor in it to serve as a storage impulse. This capacitor is also connected to the diagonal of the diode bridge and connected to the primary winding of the transformer coil.
When the device is connected, the capacitor accumulates a charge, powering an additional circuit. When the button is pressed, this charge is directed directly through a resistor and an additional thyristor directly to the welding electrode. There is an additional barrier when it comes to contact.
To recharge the capacitor, you need to release the button, disconnect the resistor and thyristor and reconnect the auxiliary circuit.

The strength of the pulse pulse is regulated by an additional resistor that controls it.

This is an important description of the operation of the simplest equipment for capacitor welding, devices of which changes can be made, depending on the required tasks and the necessary output characteristics.

Need to know

For those who want to pick up their cooking equipment on their own, please pay attention to the following points:

It is recommended that the capacitor capacity be close to 1000 - 2000 µF.
For the manufacture of a transformer, the most suitable core is the Sh40 variety. Yogo optimal thickness is 70 mm.
The parameters of the primary winding are 300 turns of copper wire with a diameter of 8 mm.
The parameters of the secondary winding are 10 turns of copper bus with a cross-section of 20 square millimeters.
For heating, the thyristor PTL-50 is a good choice.
The input voltage can provide a transformer with a voltage of at least 10 W and an output voltage of 15 V.

Considering this, you can collect a completely useful device for spot welding. And although it will not be so thorough and manual, as it is the possession of a factory-made product, with its help you will be able to fully master the profession of a welder and then begin to prepare various parts.

This type of cooking is carried out using the spot method. It is easy to use if you need to weld small parts one by one, and one by one. It is important that the capacitor is not made with vicor for robots with colored metals.

Since it has become possible to carry out brewing exactly in the home, the method has become increasingly popular among unsettled brewers. This situation has added to the relevance of nutrition today. What is this process and how to prepare a brew for home brewing? We will try to present this in detail.

The first importance, which comes from the diet, is the fluidity of cooking and its environmental friendliness. A standard capacitor welding unit operates at high voltage. This allows you to save electricity and remove a clean and straight seam. Basically, it should be frozen in a micro-cooked tank, or if necessary, make large cuts. This is based on the following principle:

Capacitors collect the necessary amount of energy from themselves;
The charge is converted to heat, as it is used for cooking.

As we thought earlier, this type of cooking is environmentally friendly. The system does not require space for cooling through the presence of thermal radiation. This advantage allows you to add an hour to the term of operation of the capacitor device.

The principle of robotic capacitor welding

In the process of spot welding, parts are pressed together with two electrodes, which results in a short-hour jet. Then an arc is created between the electrodes, which heats the metal, melting it. The welding pulse arrives at the robot for 0.1 seconds, and it supplies a hot melting core for both parts of the workpiece that can be welded. If the impulse is removed, the parts will continue to shrink under the pressure of pressure. As a result, the welded welded seam is developed.

The secondary windings are generated, their current flows to the electrodes, and then to the primary winding, the pulse generated by the capacitor charge is generated. The capacitor accumulates charge during the interval between the necessary pulses on two electrodes. Particularly good results come when you go about or media. Due to the nature of the workpieces, there is no need to overextend 1.5 mm. It is possible, for all intents and purposes, that such a scheme works wonders when boiling different materials.

See the spot spawn

There are two main types of do-it-yourself capacitor welding:

Transformer. If there is a capacitor, discharge the energy charge onto the winding of the transformer device. In this case, the workpieces are moved to the welding field, which is connected to the secondary winding.
Transformerless.

Advantages

As with all other types, self-welding capacitors have low positive characteristics:

With stable operation, it is possible to save electricity;
Reliability and practicality. The fluidity of the robot allows spot welding to be accessible when cooled by air;
Robotic speed;
The brewing strum is very thick;
Accuracy. With a dose of renewed energy, the dot creates a reliable seam, a compact structure. This method is widely used for thin welding of color metal;
Economy. The current level is maintained at 20 kVA maximum. This requires additional selection of tension and stabilization of tension at the edge.

Do-it-yourself assembly diagram for the unit

The primary winding is passed through one place (direct) and then connected to the voltage source. The thyristor sends a signal to the brook diagonal. The thyristor is equipped with a special button to start it. The capacitor is connected to the thyristor, more precisely to the junction, to the diode bridge, then connected to the winding (primary). To charge the capacitor, an additional lance with the same bridge and transformer is turned on.

As the pulse corresponds to a capacitor, its capacitance is 1000-2000 µF. For the design of the system, a transformer is vibrated from a core type Ш40, the required size is 7 cm. To create the first winding, a wire with a diameter of 8 mm is required, which is wound 300 times. The secondary winding transmits the vicor of the copper bus, 10 windings. For the input, use practically any kind of capacitors, with a voltage of 10 degrees and a voltage of 15.

If the robot is able to assemble workpieces up to 0.5 cm, then make several adjustments into the design diagram. For manual signal transfer, use a MT4K series starter, which includes parallel thyristors, a diode and a resistor. The additional relay allows for working hours.

This self-sealing capacitor operates in the following sequence of actions:

Press the start button to start the time relay;
The transformer is turned on with the help of thyristors, after the relay is turned on;
The resistor is used to determine the value of the pulse.

How is the cooking process carried out?

Once we have completed the DIY welding of the capacitor, we are ready to begin work. To cook the cob, prepare the parts by cleaning them from dirt and other grains. Before placing the workpieces between the electrodes, they should be brought together in the position in which they need to be welded. Then the device starts. Now you can squeeze the electrode and check 1-2 hvilini. The charge that accumulates in the high-amplitude capacitor will pass through the welded fastener and the surface of the material. As a result, the wine will melt. Once everything is crushed, you can proceed to the final edges and weld other parts of the metal.

Before welding robots, in your home, you should prepare materials such as emery paper, grinder, knife, twist, or press or pliers.

Visnovok

Condenser welding is very easy to freeze, both at home and in the industrial zone, as we most importantly, it is even easier and easier to freeze, plus there is still a great number of transfers. With the additional information provided, you can take your knowledge to a new level and further improve the welding point in practice.

There are a number of methods for seamlessly joining metal elements, but in the middle of all this, the capacitor welding itself comes into play. The technology began to gain popularity around the 30s of the last century. The tap is used to supply the electric jet to the required location. A short freeze is created, which allows the metal to melt.

Advantages and disadvantages of technology

It is clear that capacitor welding can stagnate in industrial minds, and in everyday life. It transfers a voltage to a small device, which carries a charge of constant voltage. Such an attachment can be easily moved around the work area.

The advantages of the technology include:

high productivity of work;
durability of the installation that is being tested;
Possibility of joining various metals;
low thermal vision;
availability of additional expendable materials;
the accuracy of the elements being combined.

However, the situation arises if it is impossible to seal the capacitor without welding to connect the parts. This is primarily due to the short duration of the process itself and the limited cutting of the elements that come together. In addition, impulse control will prevent various interruptions in the boundaries.

Features and specifics of curing

The very process of joining the workpieces involves contact welding, for which a large amount of energy is consumed in special capacitors. These images are observed for a period of time (lasting 1 – 3 ms), as a result of which the thermal zone changes.

It is quite easy to weld the capacitor with your own hands, as the process is economical. This device can be connected to the main electrical circuit. For high-pressure production, the industry has developed special high-pressure devices.

The technology has become particularly popular in workshops designed to repair vehicle bodies. During the hour of operation, they do not burn out and do not succumb to deformation. The need for this additional straightening disappears.

Basic benefits before the process

In order for the condenser to be welded in Vikon on the high yak region, it is necessary to reach the attention of many minds.

The pressure of the contact elements on the part that is being crushed immediately at the moment of the impulse must be sufficient to ensure reliable connection. The pressing of the electrodes is carried out with little rubbing, thereby achieving a short regime of crystallization of metal parts.
The surface of the workpieces to be joined must be cleaned to remove impurities, so that the oxide and iron deposits do not create too much pressure when the electric jet is poured directly onto the part. Due to the presence of third-party frequencies, the effectiveness of the technology is significantly reduced.
How electrodes need to vikoristovuvat copper haircuts. The diameter of the point in the contact zone depends on at least 2-3 times the thickness of the element that is being cooked.

Technological techniques

There are three options for embedding on the workpiece:

The condenser welding point is mainly used to connect parts with various components. She is a successful victor in the field of electronics and equipment.
Roller welding consists of a large number of point connections that appear as a seam. Let the cat guess what to wrap around.
Impact capacitor welding allows the creation of elements with a small cross section. Before cutting the workpieces, an arc discharge is created, which melts the ends. After sealing the parts, welding occurs.

If there is a classification according to ownership, if it is stagnant, then the technology can be divided into the characteristics of the transformer. As a result, the design of the main attachment becomes lighter, and the bulk of the heat is seen in the middle contact zone. The main advantage of transformer welding is the ability to provide a large amount of energy.

Do-it-yourself capacitor point welding: diagram of the simplest installation

To join thin sheets up to 0.5 mm or smaller parts, you can assemble a simple structure, prepared in a commercial kitchen. In this case, the pulse is supplied through a transformer. One end of the secondary winding is connected to the main part, and the other to the electrode.

When preparing such a device, the circuit may become stuck if the primary winding is connected to the electrical circuit. One of its ends is output through the diagonal of the switch near the diode bridge. On the other side, a signal is supplied directly from the thyristor, which is located under the start button.

The pulse vibrates at times from an additional capacitor, with a capacity of 1000 - 2000 µF. To prepare a transformer, you can use a Sh-40 core, which has a thickness of 70 mm. The primary winding with three hundred turns can be easily made from a 0.8 mm core with PEV markings. For control, use a thyristor with the designations KU200 or PTL-50. The secondary winding with ten turns can be made from a copper busbar.

More tightly sealed capacitor: diagram and description of the self-contained device

To increase the signs of tension, you will have to change the design of the device that is being prepared. With the right approach, it will be possible to join the darts with a webbing up to 5 mm, as well as thin sheets of stitching no more than 1 mm. To activate the signal, a contactless starter with MTT4K markings, rated for an 80 A electric current, is activated.

Set the core block to turn on a thyristor connected in parallel, a diode and a resistor. The demand interval is adjusted by an additional relay located in the main circuit of the input transformer.

The energy is heated in electrolytic capacitors, connected to a single battery; in the following table you can learn about the necessary parameters and the number of elements.

The main transformer winding is made from a 1.5 mm crossbar, and the secondary winding is made from a copper busbar.

The operation of a self-propelled device is based on such a scheme. When the start button is pressed, the trigger relay turns on the transformer of the cooking unit behind the additional contacts of the thyristors. The shutdown occurs immediately after the capacitors are discharged. Adjustment of the pulse action is carried out using an additional exchangeable resistor.

Attachment to contact block

The preparation of devices for capacitor welding requires a manual welding module, which allows the electrodes to be fixed and moved without interruption. The simplest design relies on manually tightening the contact elements. With the folding option, the lower electrode is secured in a stationary position.

For this purpose, on the required support, the screws are fixed with a height of 10 to 20 mm and an overcut of more than 8 mm. The upper part of the contact is rounded. Another electrode is fastened to the Maidan, and it will collapse. In case of any emergency, adjusting screws will be installed, in addition to which additional pressure will be applied to open the additional vise.

The trace is sure to insulate the base from the dry maidan until the contact of the electrodes.

The procedure for carrying out the work

First, you will need to break up the point capacitor welding with your own hands, you need to become familiar with the main steps.

At the cob stage, the elements that are to be combined are prepared in the proper manner. From these surfaces one can see obstructions in the appearance of saw particles, soil and other substances. The presence of third parties will not allow the workpieces to be firmly pressed together.
The parts are connected one by one in the required position. The stench is to blame for spreading between the two electrodes. After squeezing the contact elements, a pulse is sent by pressing the start button.
If the electrical power is on, I am about to jump in, the electrodes can be pulled out. The part is ready to be assembled. If there is a need, then it is installed at a different point. The thickness of the element that is being welded determines the amount of space between the centerless infusion.

Stacking of ready-made devices

Robots can be equipped with special installations. This kit includes:

impulse-generating apparatus;
attachment for welding and clamping;
gate cable, equipped with two clamps;
collet set;
instructions for use;
plugs for connecting to the power supply.

The enclosed part

This technology for combining metal elements allows not only the welding of steel particles. With this help you can, without much difficulty, press together parts made from colored metals. However, when testing welding operations, it is necessary to ensure that all specific materials that are being tested are protected.

Having touched my hands to the Chinese brewing machine Vita (called simply PA), in which the power transformer burned out, they simply asked me to repair it.

They scoffed at those that when they were still processing, it was impossible for them to cook, strong breezes, crackling, etc. Having decided to bring it into order, I can immediately share the information with anyone who may need it. At first glance, I realized that the transformer for the PA was wound incorrectly, the fragments of the primary and secondary windings were wound around the edges, the photo shows that only the secondary winding was lost, and the primary winding was wound on the side (that’s how the transformer was brought).

This means that such a transformer has a I-V characteristic (volt-ampere characteristic) that drops steeply, and is suitable for arc welding, but not for PA. For Pa, a transformer with a tight current-voltage characteristic is required, and for which the secondary winding of the transformer may be wound on top of the primary winding.

In order to begin rewinding the transformer, you need to carefully unwind the secondary winding without damaging the insulation, and cut off the partition that separates the two windings.

For the primary winding, I used a thin copper enamel wire of 2 mm thickness; for complete rewinding, we grind 3.1 kg of copper wire, or 115 meters. We wind turn to turn from one side to the other and back. We need to wind 234 turns - that's 7 balls, after winding we'll work hard.

The primary winding and outputs are insulated with fabric electrical tape. Next we wind the secondary winding with the same dart that we wound earlier. We wind 36 turns, 20 mm2 shank, approximately 17 meters.

The transformer is ready, now let's move on to the throttle. Throttle is no less important part in PA without any fault, it is not normally practiced. The formation of veins is incorrect, because there is no gap between the two parts of the magnetic circuit. I will wind the choke on a cage like a TS-270 transformer. The transformer is disassembled and a new magnetic conductor is taken from it. Carrying out the same cut as on the secondary winding of the transformer, we wind it on one bend of the magnetic circuit, or on two successively connected ends, as you wish. The most important thing in the throttle is the non-magnetic gap that exists between the two halves of the magnetic circuit, which is reached by inserts made of textolite. The thickness of the pad varies from 1.5 to 2 mm and is determined by an experimental method for skin rash.

For a stable burning arc, it is necessary to install capacitors with a capacity of 20,000 to 40,000 uF in the lancet and the voltage of the capacitors is 50 volts. Schematically, everything is like this.

In order for your PA to earn money normally, it will be enough to earn more valuable activities.
And for those who are worried about a constant stream of light, you need to install a thyristor of 160-200 amperes in the lance, so as to be able to watch the video.

Thanks to everyone for your respect -)
