What is a plasma cutter?

A plasma cutter is a cutting tool that uses a high-temperature plasma arc to cut through metal and other conductive materials. The process involves passing an electric arc through a gas, typically compressed air, which then ionizes the gas, creating a plasma arc. The plasma arc can reach temperatures of up to 30,000 degrees Fahrenheit, which melts the metal and allows for a clean and precise cut.

Plasma cutters are used in a variety of applications, including metal fabrication, automotive repair, industrial construction, and artwork. They are ideal for cutting through thick or hard-to-cut metals, as well as for cutting shapes and intricate designs.

There are two main types of plasma cutters: handheld and CNC (computer numerical control). Handheld plasma cutters are smaller and more portable, making them ideal for DIY enthusiasts and smaller shops. CNC plasma cutters, on the other hand, are larger and more precise, and are typically used in industrial settings for high-volume production.

Overall, plasma cutters have revolutionized the metalworking industry by allowing for faster, more efficient, and more precise cuts, making them an essential tool for many professionals and DIY enthusiasts alike.

Plasma Cutter Buying Guide

  1. Before choosing the machine, the buyer should consider the inbuilt compressor Machine or an external compressor. Inbuilt compressor machines will be expensive but can perform the small cutting jobs quickly.
  2. The reliability endurance of the machine should be of the highest order. The machine shouldn’t break down during use.
  3. The machine should have a pilot arc for the stable arc with enhanced life and ease of cutting without the torch striking the metal.
  4. The machine is available with 115V, 230 V, and dual voltage. The 115 V machine is most suitable to operate on domestic power. The machine with 230V will need the Generator for the cutting operation. Can change over the dual type of machine to the required supply plug.
  5. The other important factor to consider for the machine for purchase is the thickness of the metal a cutter can perform. Always choose the machine capable of cutting maximum thickness metal. There are three types of cut rating machines.
    • A-rated cut machine-which cut the rate of 10 inches per minute.
    • A machine performs a quality cut of the thicker metal at a slow speed.
    • A severe cut that a machine performs maximum cut at the lowest rate.
  6. The duty cycle of any machine will define continuous endurance. Can run the Higher duty cycle machine for a longer time. The duty cycle of the machine is indirectly proportional to the voltage. The duty cycle will decrease with the voltage increment. Hence a machine with seven duty cycle is considered the best machine.
  7. Consideration of the weight of the machine will depend upon the type of job. A lighter weight machine will be suitable for the job to job mobility. The heavier weight machine will be ideal for the heavy cutting jobs mainly used for industries.
  8. The quality of the cut is another deciding factor for the plasma cutting machines. The plasma cuts are the more finished and clean amount which wouldn’t require further cleaning.
  9. The buyer should consider the operating cost of the machine. An expensive machine’s operating cost will be less as compared to the less costly machines.
  10. The large cutting torches are preferable in workshops where the operator needs to use the machine without moving the machine for cutting the heavier jobs. But a short torch will be preferable for the portable machines to suit the space.

While considering the cost of the machine, the above ten factors need to be taken into consideration. An expensive machine doesn’t need to have all the above ten essential factors.

What are the different types of plasma cutters?

Air Plasma

This machine is used for cutting metal, plastic, and other materials without any use of heat. It is a new technology that is environmentally friendly and cost-effective. This machine is able to cut through most materials with a diameter of less than six inches. The plasma cutter also has a remote control which allows the user to control the speed and depth of the cut. The plasma cutter can also be used for cutting pipes, but it is recommended that this be done by a professional.

Oxygen Plasma

The oxygen plasma cutting machine is a great tool for cutting metal. This tool uses a high-voltage electric arc that creates a stream of ionized air to cut through metal. The plasma cutter uses an oxygen/nitrogen mixture, which is then fed into the nozzle where it is ignited and created. The process of cutting metal with the plasma cutter leaves a clean, precise cut that has the same consistency as a laser beam. The plasma cutter has been used in industries such as aerospace, automotive, and construction

High Definition Plasma

The High Definition Plasma Cutting machine is a device that uses a plasma torch to cut through materials like metals, plastics, and composites. The plasma torch is a gas-powered arc welder that creates a plasma arc between two electrodes. The electrode ends are connected to the torch tip and the torch nozzle, respectively. The electric arc is contained by a magnetic field. The magnetic field is generated by a large electromagnet that is powered by an alternating current.

The High Definition Plasma Cutting machine has the ability to cut through materials like metals, plastics, and composites. This machine has many different uses such as cutting through thick steel plates, cutting through objects that are too heavy for traditional cutting methods, and removing small parts from larger pieces of metal.

CNC Plasma Cutter

A CNC plasma cutter is a machine that uses electricity to cut through metal or other materials. It is a modern day tool used in various industries and is commonly used to cut metals, plastics, and other materials. There are many different types of plasma cutters, each with their own specifications. For example, a CNC plasma cutter may be able to cut through metal, plastic, and other materials with different cutting speeds.

How do you use a plasma cutter?

Using a plasma cutter involves several steps. Here is a general overview of the process:

  1. Prepare the work area: Make sure the area is clean, free of clutter, and well-ventilated. Wear protective gear, including eye protection, gloves, and a mask to prevent inhaling fumes.
  2. Set up the plasma cutter: Ensure the plasma cutter is properly set up and connected to a power source. Make sure the air compressor is attached and set to the recommended pressure.
  3. Set the amperage and air pressure: Depending on the material you are cutting and the thickness, you will need to adjust the amperage and air pressure on the plasma cutter. Consult the manufacturer’s guidelines or cutting chart for recommended settings.
  4. Start the plasma cutter: Press the trigger on the plasma cutter to start the arc. Move the cutter over the material in a steady and smooth motion, following the cutting line.
  5. Adjust the speed and angle: Adjust the speed of the plasma cutter to maintain a consistent cutting speed. Keep the plasma torch at a 90-degree angle to the material for the best results.
  6. Finish the cut: Once the cut is complete, release the trigger on the plasma cutter and allow the material to cool before handling it.
  7. Clean up: Turn off the plasma cutter and disconnect it from the power source. Clean up the work area and store the plasma cutter and accessories in a safe place.

It is important to follow safety guidelines when using a plasma cutter, including wearing protective gear, using a fire-resistant work surface, and following the manufacturer’s instructions. With proper use and maintenance, a plasma cutter can be a valuable tool for metalworking and other applications.
