Basics of using plasma cutting tools

September 17, 2019

Are you wondering how to use plasma cutting tools ? This article will cover the basics of its use. The most effective method of cutting metal is to use a plasma cutting tool.

Hot plasma makes it possible to cut electrically conductive materials, for example: steel, aluminum, brass, and copper.

Plasma cutters can be purchased at automotive and welding stores, as well as industrial and fabrication shops. Plasma cutters have become popular in the art of metal fabrication.

Advantages of a plasma cutter

Plasma cutters are known for their high speed and precise cutting capabilities. With their low operating costs, they are perfect for both large-scale and small-scale jobs, such as creating metal crafts.

Plasma cutting can be used to make shapes, process metal, and even cut materials. These features give it an advantage over tools that use acetylene and oxygen to cut a variety of materials.

How does a plasma cutter work?

A plasma cutter has a so-called torch, which consists of three main parts: an electrode, a gas burner, and nozzles. Gas pressure is sent through the so-called torch, after which the electrode ignites and the nozzles touch the work metal, creating a kind of circuit.

The gas escaping from the torch is heated by the spark created by the metal and the electrode, creating a plasma. The electric plasma cuts the metal, while the shielding gas protects the cut area as well as the welding area.

Handheld plasma cutters - These types of cutters are used by those who have a hobby of making metal crafts or need to transport this tool frequently. A handheld plasma cutter has a hand-operated plasma torch that cuts metal.

Mechanical plasma cutter - used for larger cutting jobs, as it is not controlled manually, since it is mounted on a table and it is on this table that the metal is cut, and this cut and the depth of the cutting torch are controlled by a computer system, which can also melt the metal and laser cut it.

Safety precautions required when using plasma cutting tools

Plasma cutting uses an electric arc, so we need to wear a welding helmet and safety glasses to protect ourselves from the glare.

It will definitely start to fly sparks, so it would be a good idea to use welding gloves, an apron, and a jacket for protection to avoid burning your body.
