If you are considering getting into the world of cnc plasma cutting, there are a few things to consider first. This first step takes you through the cnc plasma cutting process and how it works.
What is this?
CNC plasma cut refers to the cutting of metal using a plasma torch controlled by a computer. Plasma cutters work by forcing gas when air is pressed at high pressure through the mouth. Once an electric arc is brought to a gas, ionized gas or plasma is created; that is the fourth condition. It, too, cuts through the middle of the metal.
CNC Plasma Cutting Machines vary widely in size, price, and performance. The machines are reliable and fast, cutting in half and cutting steel with speeds of up to 500 inches per minute. Plasma cutters need plasma gas and gas to help them work, varying depending on the cut.
Table setup
When it comes to the machinery itself, what matters most is location and security. Unlike most hobby cnc systems, cutting plasma requires a large area in a ventilated place to operate safely. It is not a machine that you can safely tap into a corner as you can a 3d printer.
The machine needs space all around the buffer for any lost spark. Similarly, the floor should have concrete or other fireproof material.
Space is also required for gas or compressor and the computing system. To prevent the plasma arc from interfering with the computer, the machine must be low, and the computer must be on an unstable power supply (ups) to ensure constant reliable power.
If you plan to install your cnc plasma cutting table, ensure your store power is sufficient (according to the specifications). Settings for DIY cnc plasma table can be found on instructables.
Shop ventilation
In terms of inhalation, there are two main plasma tables: downdraft and water.
Downdraft tables have air-conditioned enclosures designed to draw smoke and debris from used metal. In most cases, the working area has holes through which particulate matter is absorbed. In this case, one has to connect the turbine structure of the exhaust system to the plenum in the center of the table.
The water table allows the part being worked together with the plasma torch to quickly sink to the bottom, lift, carry debris, and keep the components cool. In this case, the normal ventilation of the workshop should suffice.
How to keep safe while using the cnc plasma machine?
A plasma cutting machine is used to cut various materials for use, but it does not come without any risk. It is essential to keep the head out while operating this cnc plasma cutting machine.
Wear a plasma helmet or mask
Protect yourself with a plasma hat from plasma sparks that could hit your eyes if they remain unprotected. The plasma helmet also protects the watch from damage caused by light-stroke plasma.
And again, the clothes and gloves you wear should be non-flammable so that your body will not be exposed to the elements. Also, the CNC Plasma Cutting Machine operator does not have to carry matches or light butane. You should wear high-heeled leather shoes or boots so that the fire will not hit your feet and injure you. Looking at the softness of plasma can cause damage to your eyes and can lead to blindness.
Protect yourself and others
Practices such as welding, cutting, and gouging are noisy and need ear protection. Plasma emits light and ultraviolet light, and harmful radiation. Therefore, it is essential to cover your face and entire head to prevent injury. Use a well-placed face shield with filters and metal cover to protect the face, neck, eyes, and ears from harm while using a plasma machine. Even those in attendance should wear protective glasses. In addition, use nails and protective gloves when handling hot-cut items.
Welding gloves protect your hands
When working with an industrial CNC plasma table , a person should wear hand gloves to protect their hands from accidental injury. Hand protection is one of the most critical safety measures a user should be aware of when handling these components.
Also, remember that if you use a plasma machine and the gloves you are wearing do not have the right amount of grip, you need to replace them.
Also, if you are handling and when loading heavy and non-heavy metal parts that are usually greased, then you should wear gloves to prevent the handling of slippery agents. Whether the manual lathes, milling machines, or pedestal drills, there is always a need for a safe grip to reduce the risk of injury when the fingers are touched.
Cover your legs while using the machine
Yes, it is not possible to avoid wearing shorts in the summer, but wearing jeans and closed-toed clothing is recommended when using a plasma machine. Exposure to emf fields during cutting or roasting may increase the risk of injury from a hot flame operating on the machine. Therefore, using the machine is very important to cover your whole body.

Tied and tied boots protect your feet from all sparks and drop pieces.
Covering your feet and preventing any metal from falling inside your boot are recommended. Also, fasten your shoes carefully and protect your feet from heat or hot metal that may fall off with cracks or cracks. Ensure the openings are well insulated to protect your feet from danger.
