Plasma cutters used in welding

To produce plasma, the pilot arc uses two cycles, thus eliminating the need for initial contact. A high voltage and low current circuit is used to start a very small high intensity spark unit in the body of a flashlight. That is why a small cup of gas is formed. This pilot is nothing but an arc. The pilot arc consists of a reverse current connected to the head of a flashlight. Before the plasma arc reaches the workpiece, it retains the pilot arc itself, where the central plasma cutting arc burns. Plasma arc is present in all ranges and is very hot. Plasma cutting arc is a well known arc.

Plasma cutting is an effective way to cut hard and thin materials. Strong torches can cut two-inch hard steel plates, while computer-controlled torches can cut six-inch steel. Plasma cutters form hot and highly localized “cones”, which are perfect for cutting metal into angular or curved shapes. Safety equipment and steps should always be with the welder. Eyeglasses and face masks are needed to prevent eye damage. This is called arc and derby damage.

Getting started is a combination of small ways. The plasma cutter uses a few steps to start the arc. Touching the torch with a work piece creates an arc in some units. Some cutters use high voltage and high frequency circuits to start the arc. High frequency emissions with the risk of electric shock, catching spark gas, difficulties in repairing PF and many other disadvantages. Most pilot arcs start in other ways, such as when electrodes and mouths, plasma cutters operate near sensitive electrons such as computers and CNC devices. The nose is called the cathode and the electrode is called the anode. As the plasma gas begins to flow, the slope moves forward. The third most common method is to operate the capacitors in a silicon-powered rectifier main circuit.

Inverter plasma cutter is a very difficult method. Analog plasma cutters typically require 2 kW, which often uses a service frequency transformer. The inverter repairs the main DC supply of the plasma cutter. It is also available for high frequency transmitters. In addition, the high frequency transmitter provides high efficiency in the conversion process.

Plasma cutters consist of many parts that need to be checked periodically. This will save your cutter and give you high quality deductions. Using the right replacement parts will give you better cutting quality and prolong the working life of the tools.

The plasma at the top of the plane collects the cutting gas and ignites the flow to convert the concentrated gas into plasma. In contact with metals, plasma is protected from inert or perhaps semi-inert gases. Plasma has enough power to cut all the cut metal. Temperatures up to 30,000oF reach the plasma, which together with the force exerts pressure on the head of the mouth.

Corrosion parts in plasma cutting machines: shields, slopes, electrodes and seals will all last longer with proper service.


The plasma arc is made up of an electrode, which is the main function of the electrode. You can tell the depth of the hole by inserting the image. The cutting quality is reduced by the electrode, which can damage the plasma flashlight. The most common reason is the correct alignment of the torch parts. However, proper regulation of gas flow, air pollution, increased humidity and gas leakage can also contribute to electrode wear.


Plasma cutting lines compress plasma gas through a narrow pipe of a certain diameter, which increases its speed and power. Damage to the nose can be caused by incorrect cutting, incorrect adjustment of the plasma cutter, or replacement of incorrect parts. Regular service schedule and use of original equipment manufacturer (OEM) parts prolong the useful life of plasma cutters.

the shield:

As the name implies, the shield protects the mouth pieces from damage. The most common problem with a hole in an airplane is that the hole gets stuck in the hole. Garbage or rubbish can usually be removed, but the shield needs to be replaced if the hole is not broken or round.
