Aug 13, · I created this design after thinking over some of the feedback I received on my previous video about converting an arc lighter in a mini plasma cutter (seen. Sep 13, · His most recent instructional video titled “How To Make A Plasma Pen & Micro Torch,” comes in response to feedback from an earlier clip on how to make a mini-plasma cutter out of an arc elvalladolid.com both projects are doable, the plasma pen is arguably cooler because it allows you to do more than cut paper.
This is my second Instructable and english is not my mother tongue, so I ask you guys some patience for the possible formal inaccuracies. I decided to enter this Instructable in the Teach It! I belive that it fits that contest because by this Instructable you are going to learn how to deal with the fourth state of matter: PLASMA, that i think is not just trivial stuff. Indirectly, you will also learn a bit of glass working. Disclaimer: if you are going to reproduce this Instructable, be aware of the plassma it concerns: deadly high voltage current will be used toorch the final product may be able to produce a little amount of x-rays.
I'm not responsable for any damage to property or persons, due to the imitation of this tutorial. Even If the aim of this Instructables is not to make an advanced lesson about the plasma phisics I'm not able to do itbut only to teach you how to produce it, it may be a good thing to have a vague idea of what it is.
You may be accustomed to the first three states of matter: solid, liquid and gas. But how to get mildew out of wood furniture is a less known state called plasma, that ironically, is the most abundant form olasma matter in the Universe. Thats because most stars are in a plasma state. Technically, plasma is a ionized gas that consists of a set of electrons and ions but globally neutral.
A neutral gas is dielectric this means it can't conduct electricity but if it is subjected to an sufficiently strong electric field, at a sufficiently low pressure, it ionizes. It means that its particles lose their natural electronic balance, and starts to conduct electricity. Lightning is an example of plasma visible on earth. And since plasma is extremely hot in a lightning it can reach temperatures of 28, kelvins is often used in industrial cutting.
In practice, all this results into a charming glow of light with a color ranging from purple to blue. The title of this step may have crushed your expectations: " Will I need some special equipment? You said it would be easy! To run the device you will also need:. Mine is just a simple ZVS circuit, driving a flyback transformer. If you don't know what I'm talking about, you should check this great Instructables that I followed to build my generator:. If you have it, you can even use a neon sign transformer.
Vacuum pumps are expensive, thats why I'm using an old compressor form a refrigerator. I just attached a thick pvc tubing to the suction end. It works really well. We are going to build a cilindric vacuum chamber with two electrodes. After the vacuum making, rarefied air will remain in the chamber. By creating a strong electric potential difference between the two electrodes, the gases inside will pass at the sate of plasma.
This will make the glass piercing passage more easy. Due to the high temperature it will reach, it may be flaking and smudge the vacuum chamber. Now there is the fun part: you have to inglobate the anode in the back of the test tube, leaving an uncovered part of the bolt to attach the generator. It may sound difficult, but I found out that glass-working isn't that bad.
You will have to:. It will be ready when the flame will turn orange from blue, ad the glass will glow orange as well. Using multiple torches will make everything more easy. The result of the previous step may be imperfect. To check this it will be sufficient to blow through the test tube.
If you feel any air leak from the bolt area, you will have to seal it with some epoxy, or wrap it with some insulation tape. Tape works better because by pumping vacuum, it will bend, filling the leaks itself. It is also easy to change if you need to. If you did everything right there should be 12cm of distance between the two electrodes. To achieve this, i made a simple plywood stand.
Cardboard will do fine as well. I flew over the base making steps, but you can see anyway some pictures of it. After reaching a good vacuum just start the generator. A clear stream of plasma appears to your eyes. Stream deflection: since plasma is sensitive to magnetic fields, is tirch to deflect the stream with a strong enough magnet as shown. Since plasma is etremely hot, is not advisable to keep the device turned on for more than seconds. Question 1 year ago.
Question 1 year ago on Step Question 2 years ago. I have a Solid state transformer 12 kV, 35 ma I assume that way too low to generate Plasma this way.
It also cannot handle a load so would a vacuum like that produce a load mqke burning out the transformer? Please, when you have the time could you answer quickly. Would rectify it with DC work any better? I am wondering rectifying it to 25 kV to 36 kV work? Reply 6 years ago on Introduction. Actually I'm working on a co2 laser, but there is a big obstacle: i need a NaCl lens and i have no idea where hiw find it for cheap.
Im thinking about to build one by myself but i know its a desperate attempt. Reply ti years ago. Yeah, you need O rings to create a high-pressure vacuum at high atm and pump CO2 with nitrogen and other gases. I studied in Photonics and did a thesis on building a Nitrogen laser.
You need rectifiers usually to get to 40, volts and cooling. The hardest part would be the NaCl lens for a CO2 laser. You can get tubes of CO2 but they are hw. It really hard for anyone to find unless your super rich to build a CO2 laser.
However, it can be done. And no moisture present or the NaCl lens would be destroyed. Lpasma you have the finished product is there a way to transfer the plasma into a magnetic field for a sustained amount of time, or would the plasma simply revert back into gas once it was outside of the test tube?
Can you put a tuned transformer over the tube to set up a ion inuction how to make a plasma torch electromagnetic induction ionization loop with power removed for maoe power source? Can anyone help? Reply 6 years ago. Your way plaama of where What are the tax rates in the united states was in 8th grade.
This is something I hear a lot and isn't really correct. Electricity the flow of tkrch through a conductor will take every path that leads to a ground makes a circuit.
Only the amount of current amps will be determined by the resistance. Take the simple parallel circuit diagram I uploaded. Then how to make skin fair and clear are saying that current will only be measured on the branch that R1 resides on.
This isnt true. While most of the amps will be measured through R1. The second branch will have the same amount of Volts and some Amps. Yes the Amps are much less because of the higher resistance, but their is still current flow. Introduction: Plasma in a Test Tube. By Peris The Majestic Follow. More by the author:. Hi everyone! Mine is brass made, but it doesn't really matters.
For this instructables you in what movie did ed harris play christof also need the following tools: 1 Butane torch. To run the device you will also need: 1 A high voltage generator that can push out at least Kv at mA. You can look at the picture for more details. Watch the video in the last step to see it working! The bolt will be our cathode, but first you have to do a few modifications: - Sharpen the end of the bolt using the grinding wheel.
The anode block will also be our attachment for how to make a plasma torch vacuum pump. You will have to: - Drill a hole in the cork cap, just a little tighter than brass pipe.
You will have to: 1 Wear safety todch 2 Heat up with the torch the back of the test tube to soften the glass. This will shape a glass protuberance. Read the tags on the pictures for torcg details. Now it's time to set up the device: 1 Assemble the chamber. Now everything is ready for the show!
Jul 07, · Firstly, take the DC adapter and connect two wires at the two output terminals of the adapter output jack. Take one of the strongest HB pencil leads. Connect the pencil to the positive part of the adapter output wire and the foil paper with the negative terminal of the adapter output wire. Now hold the wire that holds the pencil lead. 2) Heat up with the torch the back of the test tube to soften the glass. The best way is turning it constantly on the flame, making a 30° angle as shown in the picture. It will be ready when the flame will turn orange from blue, ad the glass will glow orange as well. Using multiple torches will make .
A plasma torch also known as a plasma arc , plasma gun , plasma cutter , or plasmatron is a device for generating a directed flow of plasma. The plasma jet can be used for applications including plasma cutting , plasma arc welding , plasma spraying , and plasma gasification for waste disposal.
Thermal plasmas are generated in plasma torches by direct current DC , alternating current AC , radio-frequency RF and other discharges. DC torches are the most commonly used and researched, because when compared to AC: "there is less flicker generation and noise, a more stable operation, better control, a minimum of two electrodes, lower electrode consumption, slightly lower refractory [heat] wear and lower power consumption".
In a DC torch, the electric arc is formed between the electrodes which can be made of copper, tungsten , graphite , silver etc. In DC torches, the carrier gas can be, for example, either oxygen, nitrogen, argon, helium, air, or hydrogen;  and although termed such, it does not have to be a gas thus, better termed a carrier fluid.
Furthermore, the flow-rate of the carrier gas can be raised to promote a larger, more projecting plasma jet, provided that the arc current is sufficiently increased; and vice versa. The plasma flame of a real plasma torch is a few inches long at most; it is to be distinguished from fictional long-range plasma weapons. There are two types of DC torches: non-transferred and transferred. Whereas in a transferred torch one electrode is outside and is usually the conductive material to be treated , allowing the arc to form outside of the torch over a larger distance.
In addition, the discharge generated by this particular plasma source configuration is characterized by a complex shape and fluid dynamics that requires a 3D description in order to be predicted, making performance unsteady. The electrodes of non-transferred torches are larger, because they suffer more wear by the plasma arc.
The quality of plasma produced is a function of density pressure , temperature and torch power the greater the better. Close up of a Hypertherm HyPerformance plasma torch cutting metal.
