A plasma nut cuts through steel.

If you like to work with metals - whether hobby or industrial - you will find that using a flex and a metal drill can not guarantee all the work (such as cutting metals accurately).

Since the plasma cutter remedy. In our Plasma Cutter Comparison 2018, you will learn how to use the cutting device to process metallic materials and what distinguishes the best plasma cutter. We also want to give you a purchase advice, after which you can decide what to look for in a cheap plasma cutter.

1. Why should I use a plasma cutter?

1.1. The plasma cutter: With 30,000 degrees against the metal

Plasma torches, in contrast to flame cutters (autogenous flame cutting) have a high flexibility.

Traditional cutting torches use a flame to heat the material to be processed to the ignition temperature - ie the temperature that must be reached in order for the material to burn automatically by supplying air.

The plasma cutter can do it cut more materials and the cut is even with harder materials still possible.

Therefore, we have listed the advantages and disadvantages of the plasma torch:

  • It is possible to cut all electrically conductive materials
  • the cutting speed depends on the electrical conductivity of the material and not on the hardness
  • hardly any heat loss to the environment
  • low volume
  • exact cutting performance
  • higher investment costs than for cutting torches
  • high power consumption

1.2. How does a plasma cutter work?

What is plasma?

Plasma is a mixture of which charged and neutral particles consists. These can be heated strongly by electric discharge or laser pulse irradiation.

Plasma Cutter Comparison 2018: 2018

During the arc, gas becomes electrically conductive during ionization.

Two electrodes, one on the plasma torch and the other on the material to be processed itself, form an arc. The plasma torch is connected via a tungsten electrode to the power source.

In the arc, atoms or molecules are ionized. By this is meant that strongly heated plasma is produced by impact ionization by removing the electrons of the atoms or molecules.

Compressed air is mixed with an electric arc via a cutting nozzle, with the result that a gas with a very high energy content is formed, which in turn can be converted into heat during the cutting process. This allows plasma cutters to produce temperatures of around 30,000 degrees Celsius, which cut through aluminum, cast iron, copper, steel and even stainless steel.

Therefore, the plasma cutting in rescue is indispensable to cut people in accidents in no time from the metal wrecks.

The ignition:

There are different ignition variants: on the one hand, those that ignite contactlessly to the material (high-frequency and low-frequency ignitions) and on the other hand, those that have direct contact with the material (contact ignition).

Is a plasma cutter suitable for private use?

Even for hobbyists plasma torches are attractive, since the hand-operated plasma cutting devices do not require additional gas and work with compressed air. For private use, you should do without a Flex saw if you want to save time and achieve accurate cutting results.

1.3. How is the plasma cutter constructed?

A plasma cutting device is made up of a large number of components. These include a power supply, a ground cable, a handpiece, a power source, a compressed air supply line and usually a built-in cooling system to cool the extremely strong heat.

2. How many plasma cutter types exist?

There are several types of plasma cutters that fall into two categories: machine operated and hand operated plasma cutters.

Types of plasma torchparticularities
plasma torch (which are operated by hand)
  • relatively easy
  • easy handling
  • Lower cutting quality when cutting than machine-guided burners
  • low amperage (max 125 amps)
  • hardly any costs, as compressed air is used
Machine-guided plasma cutter (general)
  • especially difficult
  • firmly mounted
  • high current (300 - 1,600 amperes)
  • Plasma cutter plant used in metal industry (e.g.
Simple pneumatic cutters
  • no exact cutting process
  • for non-demanding material, which hardly requires cut quality
  • Compressed air or nitrogen as plasma gas
  • hardly any costs, as compressed air is used
Mixed or dual gas cutter
  • relatively exact cutting process
  • for demanding material, which requires higher cutting quality
  • high current (up to 1,600 amperes)
  • Two different gases are used depending on the material, also to prevent oxidation
Fine beam plasma cutters (because of the high quality too Quality plasma torch to be named)
  • exact cutting process
  • for the most demanding material, which requires high quality of cut
  • two or more gases are used depending on the material
  • Cutting head is structured differently
  • Use of mixed gas consoles

3. Purchase criteria for plasma cutters: You must pay attention to this

We have compiled some purchase criteria to give you a purchase advice.

3.1. Input current and mains voltage

Plasma Cutter Comparison 2018: comparison

If the plasma torch exceeds the fuses of the house, an electrician can provide you with a power connection.

The desired performance can only be achieved by a plasma cutter if both the input current and the mains voltage are suitable. The required mains voltage (average voltage) is either 230 or 400 volts. 400 volts are equivalent to heavy current and require a special power connection or a power generator.

Normally, the current in normal homes is 16 amperes. If the input current - ie the current that is drawn from the socket by the welder - is more than 16 amps, additional protection using special cables is necessary.

We therefore recommend that you opt for devices that manage with 16 amperes and 230 volts. However, if you need more power, an additional generator becomes indispensable.

3.2. MEASUREMENTS AND WEIGHT

If it is important for you to easily transport the plasma cutter or if you have limited space available, it is important to pay attention to dimensions and weight. The weight can range from about 9 kg to almost 40 kg. Devices with approximately 40 kg are usually not transportable by a person over longer distances. The dimensions are similarly variable: from 41 x 19 x 31 cm, the dimensions can reach up to 56.5 x 28.5 x 52 cm.

3.3. INVERTER TECHNOLOGY

Since plasma torches require AC to generate an arc, it is necessary to have a Using transformer that converts DC into AC, Since these transformers always have to be brought along and incur additional costs, some cutting torches have an inverter that carries out this conversion. This minimizes costs and increases the life of the device.

3.4. COMPATIBILITY OF COMPRESSOR AND WELDING MACHINE

Plasma Cutter Comparison 2018: 2018

The Telwin Technology Plasma 54 has an integrated compressor. This is rarely the case.

Often the compressors necessary for the compressed air are not supplied and must therefore be purchased separately. You should pay attention to how much compressed air the respective compressor can produce and how much of it the respective welding machine needs.

3.5. power

Cutting torches have a control range that specifies how much amperes can be set. The higher the current, the lower the cut can be. With a current flow of 40 - 50 amperes, materials with a thickness of 10 - 15 mm can be cut through. At 100 - 120 ampere, even a thickness of 30 - 35 mm can be mastered. A device with such a high cutting thickness is usually not needed for home use. 40 amps are enough to cut steel of standard thickness with a plasma cutter.

5. Questions and answers around the topic of plasma cutting

5.1. Which gas for which plasma cutter?

Gas is normally only used in machine-operated plasma cutters, for example in the form of protective gas mixtures of argon and hydrogen. Hand-operated plasma cutters usually use compressed air instead of gas.

5.2. How much does a plasma cutter cost?

Cheap plasma cutters can already be purchased for less than 300 €. The professional tools, which are mainly used in the industry and need a much higher current, however, can cost up to € 1,000. For hobbymäßigen use cheap plasma cutter are sufficient.

5.3. CAN PLASMAGERS TICK WIG?

Plasma Cutter Comparison 2018: plasma

The CT-520 (plasma cutter Sungoldpower brand) is a TIG welding machine and has the necessary welding technology.

Tungsten inert gas (TIG) welding is not possible with most plasma torches as they focus on plasma cutting materials. Inverter welding machines, which are also TIG welders, sometimes cost a lot. To weld TIG, you should choose a suitable device.

5.4. Is there a plasma cutter test of Stiftung Warentest?

If you are wondering which plasma cutter is good and rely on Stiftung Warentest, we have to disappoint you: The Foundation has unfortunately not performed a plasma cutter test, which is why we can not present you with a plasma cutter test winner. The manufacturers Stamos, Berlan and Bulkston, however, have proven to be of high quality, which is why their products are recommended.
