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.
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.
Is plasma cutting cleaner then a torch cutting system?
plasma arc cutting (PAC) systems were much less expensive.Plasma cutting systems can be either plasma cutting tables or handheld torches. A larger, industrial plasma cutting table will obviously cost more
How much is temperatare on plasma cutting arc?

How does a Carbon Arc Torch work?
You have two electrodes mad out of carbon, and then you cause a sparc to arc over from one electrode to the other. By maintaining this arcing you get light.
In MIG welding what are the polarities of the torch and the work-piece and what is the fundamental reason for this?
MIG welding works only with reversed polarity, DC+, + at the torch. The reason is mostly the stability of the arc. Using DC- will result in a very unstable arc with lots of spatter.
What is Difference between plasma arc and plasma torch?
From my research...the're basically the same phenomenon. Some are larger than others, but I, think, they both tap the "Aether", "Zero-Point" or "Vacuum" energy, since even Plasma Physcists can't explain why the 10,000 + Deg temperature is so high. Zerwell www.zerwellenergy.com
Where can a person buy carbons for a vintage twin-carbon arc torch?
Any welding supply carries or can order for you, air arc carbon rods. They are the same that is used for air carbon arc gouging. Carbons are produced in two shapes, flat and round and various sizes. You would want the round ones.
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 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.
Is it safe to repair the frame on late model ford explorer?
yes, yes it is. But only whith the use of a plasma arc torch and nickel prodnium welding rods. A big chunk of 2x4 and a ratchet strap also help.
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.
