“A plasma is sometimes referred to as being “hot” if it is nearly fully ionized, or “cold” if only a small fraction, (for instance 1%) of the gas molecules are ionized, but other definitions of the terms “hot plasma” and “cold plasma” are common.

about 3,000 K.

Originally Answered: Can we turn water into plasma (the four fundamental states of matter)? Yup. You start with water which gets turned into steam and then plasma as you add heat. The energy to break the the hydrogen-oxygen bonds in water requires about 4.7 eV.

Plasma is made of free electrons and the positively-charged atoms (ions) which are left behind when an electron leaves. So there’s actually no plasma in the liquid water itself, although the steam (gaseous water) can become part of the plasma.

The maximum core temperatures for nitrogen at 15 kW and 25 kW are 9100 K and 9700 K, respectively. For oxygen plasma, the maximum temperature for 15 and 20 kW are 9000 K and 10 000 K, respectively. Similarly, for air plasma, maximum temperature is 6600 K for 15 kW and 7200 K for 29.5 kW.

Plasma is the fourth state of matter. It is when something becomes so very hot that it enters the state of plasma. It is NOT on fire but is so hot that it radiates light and heat.

A plasma looks identical to a gas. As you heat the plasma up, it starts to act a bit differently like an ionised gas, and if you heat it up enough, it acts a little bit like the Sun. If you heat a gas up sufficiently hot enough then the electrons will have enough energy to escape individual atoms.

Plasma is superheated matter – so hot that the electrons are ripped away from the atoms forming an ionized gas. Researchers have used the properties of plasma as a charged gas to confine it with magnetic fields and to heat it to temperatures hotter than the core of the sun.

Plasma is a kind of matter very similar to gas in which atoms have been ionized. It is very hot and lets off radiation (also in the visible spectrum) due to recombination so it might already be considered flame.

Naturally occurring plasmas can reach temperatures of up to 106eV (1eV ~ 11600K) [1], in industrial ap-plications maximum temperatures lie around 1eV [2].

A plasma cannon (also called an electrothermal accelerator) is an experimental projectile weapon, which accelerates a projectile by means of a plasma discharge between electrodes at the rear of the barrel, generating a rapid increase in pressure.

Usually, in normal conditions, we can say that the electrode will wear out first during machine cutting. Typical life time of a set of consumable should last about 1 to 3 hours for about 120 A of mechanized cutting, it’s in function of the job. Cutting at lower current may gets longer consumable life.

2. Too slow of travel speed when cutting- Moving excessively slow when cutting (especially at higher amps) overheats the torch consumables and can cause the parts to wear out prematurely. It can also cause the arc to terminate.

Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.

Plasma cutters are used for construction works, welding, auto mechanics, and general household chores that involve cutting of metals. Ideally, all plasma cutters require an external air compressor to operate.

Tungsten is the hardest to cut and needs professional equipment to cut it properly. Other materials that cannot be cut include glass, concrete, and ceramics. These materials are non-conductive and are used to insulate electrical products.

Oxygen

Argon-Hydrogen

Gas is needed for a plasma cutter in order for it to work and create the plasma. Different gases are used depending on the type of metal you are cutting. Oxygen has become the standard gas to use when cutting steel as it offers the fastest cutting speed of any plasma gas.

The major difference between a plasma cutter and a multi-process machine is this: the plasma cutter will have one function, cutting. The multi-process machine will have several functions, usually stick welding and TIG welding in addition to plasma cutting. Then you can easily set your machine weld.

In terms of thin sheet cutting, laser cutting has more obvious advantages; In terms of cost, plasma cutting is much cheaper than laser cutting.

Plasma will produce good results for perhaps 95% of the applications out there, but you’re not going to cut watch parts with it. Plasma produces a cut edge that is as smooth as laser, but it is handicapped by a slight (4 to 5 degree) bevel in the cut face.
