A very high temperature form of welding and cutting metals, using a jet of plasma.
Arc plasma is the temporary state of a gas. The gas gets ionized after passage of electric current through it and it becomes a conductor of electricity. In ionized state atoms break into electrons (−) and cations (+) and the system contains a mixture of ions, electrons and highly excited atoms.
A typical value of temperature obtained in a plasma jet torch may be of the order of 28000 °C(50000 °F ) against about 5500 °C (10000 °F) in ordinary electric welding arc.

How is an arc created in a plasma system?
An arc in a plasma system is created when a high voltage is applied to ionize the gas in the system. This ionization generates a conductive path through the gas called a plasma column, allowing current to flow across the system. The arc produces intense heat and light, which can be harnessed for various industrial applications like welding, cutting, and surface treatment.

What are the 3 man-made plasmas?
There are many more than three uses for Plasma in technology today. They range from the plasma in your TV, or Fluorescent light, or advertising display tube, right through to plasma torches used for cutting of metals (or anything!). Also used for plasma arc welding.Plasma torches have an important use in plasma furnacesused as a method of completely destroying dangerous chemicals, such as the PCB (poly chlorinated bi-phenyl) materials. They dissociate the compound right down to the atomic level.The temperature of the plasma arc may be up to 25 000oC.
In arc welding electrical energy is changed to heat energy?
Heat in plasma arc welding (PAW) transferred arc mode is generated by the arc that is established between the electrode and the workpiece. The orifice gas inside the constricting nozzle is then heat and ionized by the arc. The ionized gas is in the form of plasma and is sent out of the constricting nozzle in a concentrated, cylindrical shape. Thus, creating temperatures greater than 10000 degrees Celsius. This process is very similar to gas tungsten arc welding (GTAW).
What do you use plasma for?
Plasma Cutters are metal working tools. Plasma cutters are generally used for cutting Metals upto an inch in thickness. They use compressed air and electrical current to create an arc similar to welding. The electrical arc heats the metal at a tremendous rate while the compressed air blows it out of the way. These pieces of equipment when used in a computerized setup or by someone with a very steady hand can create very high quality cuts.

Does water explode in a plasma arc?
Yes, water will explode in a plasma arc. Just spray water into a welding arc and you'll see it happen first hand (not recommended). Water arc explosions are used in metal forming and mining.
What is plasma welding?
Plasma welding is another name for arc welding. It is a process in which electricity super heats air to form a plasma arc. This arc transmits an electrical current to a metal surface and creates heat to melt the metal together thus creating a weld joint.
What are some different applications for plasma torches?
There are some different applications for plasma torches (or plasma arc or plasma gun) including plasma cutting, plasma spraying and plasma and waste disposal.
Can plasma arc welding weld non magnetic materials?
Plasma arc welding can weld almost any commonly used metal. It is not limited to magnetic metals, they only need to conduct electricity.

How to Use a Plasma Cutter?
A plasma cutter is a device that uses compressed air or an inert gas blown through a high speed nozzle to cut metal. As the inert gas or compressed air is blown out of the nozzle, an electric arc is formed from the nozzle to the surface of the material being cut. Some of the inert gas or compressed air is converted into plasma as it touches the material being cut, and the heat from this plasma is used to cut the metal. There are two types of plasma cutters most commonly used in commercial applications. The HF (high frequency) Contact plasma cutter initiates an arc by using a high frequency, high-voltage spark to ionise the air through the torch head. While the use of this method is quite common, it is not suitable for CNC cutting applications because it requires the torch to be in contact with the material that is being cut. The other method commonly used in commerical applications is the Pilot Arc method. This method uses a high-voltage, low current circuit to create a spark within the torch body. The creation of this spark generates a pocket of plasma gas, or a pilot arc. The pilot arc is able to maintain itself because there is a return electrical path in the torch head. The pilot arc is maintained until the torch comes into contact with the material being cut, at which time the main plasma cutting arc is ignited. Because this method does not require the torch to be in contact with the material it is cutting in order to ignite, this type of plasma cutter is used across all plasma cutter applications. Over the last decade, manufacturers of plasma cutters have continued to roll out new models that feature smaller nozzles and thinner plasma arcs. As these components have become smaller, plasma cutters have been reduced in size to the point where there are now hand-held plasma cutters. This development has made plasma cutters not only easier to handle, but also much more precise. Another benefit of the increasing miniaturization of plasma cutters has been a reduction in their cost. This reduction in cost has now made the purchase of a plasma cutter within the reach of most hobbyists.
