Inverter Plasma Cutter – For a smooth welding process by David
With world economy is heavily relying on country’s manufacturing capabilities; there is a strong need for highly advanced welding machines for different kinds of welding applications. All thanks to the advanced plasma cutters that made welding extremely easy and cost effective. Do you know how plasma is produced? To produce the plasma, the pilot arc type uses two cycle, therefore saving the need for the primary contact.
To produce a very small unit of high intensity spark within the torch body, a high voltage and a low current circuit is employed. Therefore a small pocket of plasma gas is produced. This is nothing but pilot arc. The pilot arc consists of a return electric path that is connected or built in the torch head. Until the plasma arc is not brought into the proximity of the work piece, the pilot arc maintains itself, where the main plasma cutting arc is ignites. Plasma arcs are in of all ranges and they are extremely hot. Plasma cutting arc is a well versed arc.
Inverter plasma cutter is found to be extremely effective for cutting thick and thin materials. These hand-held torches are capable of cutting up to two inches in thick steel plate and the stronger computer controlled torches can cut up to six inches thick metals. A hot and much localized “cone” is produced by the plasma cutter which is used very well for cutting the sheet metals in angled or curved shapes. Safety gadgets and steps should always be handy with the welders. Welding goggles and face shield are the instrument in eye protection and they are needed to prevent eye damage. This is called arc eye and as well as damage from derby.
In an inverter plasma cutter, different methods are used by the plasma cutter to initiate the arc. By bringing the plasma torch in contact with the work piece the arc is creates in some of the units. Some cutters make the use of high voltage and high frequency circuit to start the arc. Risk of electrocution, spark gas maintain, difficulty pf repair, and large amount of frequency emission are included with large number of other disadvantages. Lots of pilot arc starts by other means, that is when the plasma cutter works near sensitive electronic such as computers and CNC hardware the electrode and the nozzle are connected. The nozzle is known to be cathode and the electrode is known as anode. The nozzle is blown forward when the plasma gas is begun to flow. A silicon controlled rectifier is a third less common method which is processed as capacitive discharge into the primary circuit.

First, what is plasma cutting, exactly? It is a process that is used to cut steel and other metals of different thicknesses (or sometimes other materials) using a plasma torch. In this process, an inert gas (in some units, compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the cut.
Process
The HF Contact type uses a high-frequency, high-voltage spark to ionise the air through the torch head and initiate an arc. These require the torch to be in contact with the job material when starting, and so are not suitable for applications involving computer numerical controlled (CNC) cutting.
The Pilot Arc type uses a two cycle approach to producing plasma, avoiding the need for initial contact. First, a high-voltage, low current circuit is used to initialize a very small high-intensity spark within the torch body, thereby generating a small pocket of plasma gas. This is referred to as the pilot arc. The pilot arc has a return electrical path built into the torch head. The pilot arc will maintain itself until it is brought into proximity of the workpiece where it ignites the main cutting arc. Arcs are extremely hot and are in the range of 25,000 °C (45,000 °F).[1]
Plasma is an effective means of cutting thin and thick materials alike. Hand-held torches can usually cut up to 2 in (48 mm) thick steel plate, and stronger computer-controlled torches can cut steel up to 6″ (150 mm) thick. Since plasma cutters produce a very hot and very localized “cone” to cut with, they are extremely useful for cutting sheet metal in curved or angled shapes.
