The device for plasma cutting and welding: the best models

Plasma devices for welding, cutting, soldering have gained wide distribution by providing the possibility of performing tasks with high efficiency in a short time. With the help of them you can work with almost any metal and electrically conductive materials.

Apparatus for plasma cutting and welding: description

Cutting occurs by melting and mixing the metal with high-temperature plasma, which is created by an electric arc from an inert substance. Thus, in the device, atmospheric ionized air is guided through the hole in the burner under pressure in the required amount and is transferred to a plasma state.

The final result and efficiency can be improved by using several kinds of inert gas, which is especially important for non-ferrous metals. That's why it's worth to take care when selecting devices and take into account all the parameters.

Selection

The device for plasma cutting and welding is suitable for processing refractory, non-ferrous metals (aluminum, copper), black metal (cast iron, stainless steel and variants with various alloying), as well as other types of materials. Today, the stores offer an extensive range of tools, to choose the best option, you need to determine the current tasks and operating conditions. After that, a selection of suitable models is made.

The main criterion is the materials with which the device can work. It is recommended to choose an aggregate with a wide range of functions and the ability to cut various metals. At the same time, it should be noted that the cost directly depends on the functional and brand awareness. Also you need to pay attention to the thickness of the cutting. Most often this parameter is indicated for sheets of steel, the least common is the designation for stainless steel. From this information, one can understand the possibilities of cutting various variants.

Arc ignition

All models are united by an identical scheme of work and general design, while these parameters are the same for any manufacturer. The difference lies in the way the arc is ignited, the following options are possible here:

• The activation of the pilot arc excites the plane of the main element. That is, a pilot arc with low power, which is on the additional circuit of the plasma torch, is first activated. With the help of compressed air an arc is formed, it closes on the plane of the material, thereby forming the main arc. The device for plasma cutting and welding with a similar ignition method is the best option for working with metal crate and mesh.
• Excitation with high frequency. In this case, the formation of the arc occurs only under the condition of an electric discharge between the head of the plasma torch and the sheet of material. This technique today is the most common.
• Contact ignition. The arc arises when you touch the workpiece. Most often you can find on the devices of the budget category, characterized by a small current strength. They are characterized by rapid wear of the nozzle of the plasmatron and its other parts. Currently, manufacturers are increasingly setting other options for ignition.

Taking into account the information mentioned above, it will be easier to determine the desired model and not to be mistaken with the available properties.

Advantages and disadvantages

The device for plasma cutting and welding, the photo of which is presented above, has many positive aspects, among which it is worth noting the following:

• The quality of cutting is characterized by high accuracy and accuracy. Even with a small experience of the relevant work, it is easy to prevent such drawbacks as the inflows and grate on the surfaces being treated.
• Security. The probability of ignition is minimized in the absence of explosive and flammable gases. Similar characteristics can only provide an arcuate manual method.
• No deformation of sheets, waves and cracks on metal surfaces.

Some devices are quite expensive, which is the only drawback. At the same time, you can always try to find a variant with a suitable price and the necessary characteristics. To perform cutting at home, the unit with average power characteristics will be quite sufficient.

"Gorynych"

Device "Gorynych" - the device for plasma welding and cutting of the Russian production is suitable for work related to high-temperature exposure. It is possible to use both for metals and for other categories of materials not subject to combustion. It is an electric arc plasma generator formed by heating an electron arc. Evaporation of the working composition, reaching the ionization temperature, is carried out by a plasma jet under pressure. As a working fluid may act ethyl alcohol or water, the choice of this or that option is carried out in accordance with the tasks. The jet has a temperature of 6000 degrees. The main elements of the device are the control unit and the plasma generator.

"Gorynych", a plasma welding and cutting machine, reviews are mostly positive. Many users note its high speed and multifunctionality.

"Svarog CUT 40 B"

The device is small in weight and compact in size, its main purpose is to handle thin materials. It is based on the inverter circuit and special transistors. The unit is equipped with an euro-connector for the burner and a convenient control panel. During the work, there is no deformation of the material, it is desirable to cut the sheets with a thickness of 0.12 cm.

It has the following working principle: the current approaches the electrode of the plasma torch, the plasma torch itself is ignited by an oscillator with a high frequency after pressing the button.

Pluses:

• No rollover due to sufficient stability;
• Economy;
• low cost;
• There is no need to create certain working conditions;
• Intuitive control;
• Convenient transportation due to a special handle and a small mass.
