Plasma Cutter Basics

What is a plasma cutter? A plasma cutter is an electrically conductive cutting machine that uses an accelerated jet of hot gas known as plasma to cut through materials. Typical materials for plasma cutting are steel, aluminum, brass, copper, and stainless steel, but many other conductive metals can be cut, too. To learn more, read our plasma cutting 101 guide. We’ll cover what a plasma cutter does, how it works, and why it’s so useful.

CAD/CAM nesting software for plasma cutters

CAD/CAM nesting software for plasma and oxyfuel cutters is available from companies such as Hypertherm. These programs help you automate and control your cutting operation, while increasing the efficiency of your cutting machine. You can import 2D CAD files and nest parts using the software, as well as save money by reducing material costs through advanced chamfering. In addition, you can set parameters and perform repeatable processes with their help.


As with any other type of cutting equipment, safety when using a plasma cutter is essential. This type of cutting equipment produces toxic fumes. Operators should keep their heads away from the plasma cutter and wear a mask, if possible. The operator should also avoid breathing in the fumes, particularly when cutting coated materials. Luckily, there are many ways to safely vent the fumes from a plasma cutter, including a suction system and the use of a respirator.


The cost of a plasma cutter will depend on many factors. One of these factors is the cutting speed. High-speed plasma machines have a large cutting area, and are faster than other cutting options. But the cost of a high-speed plasma machine also comes with many other costs. If you are looking for a machine with high-speed cutting capabilities, you need to make sure that you have enough funds to purchase it. You can check online for plasma cutter prices.


The quality of a plasma cutter can make or break your project. A higher-quality model will be easier to operate, have fewer parts, and use a design that separates sensitive components from metal dust. It will be more durable and will last longer. Cheaper models may use inexpensive components, and are not nearly as robust as higher-quality models. Consider your budget and requirements before purchasing a plasma cutter. Here are some factors to consider when choosing a plasma cutter:

Gas mixtures

When choosing the best gas for your plasma cutter, you need to consider many factors, including the type of metal, desired cut quality, productivity, and economy. In general, you should use oxygen for the best cut quality, with the lowest possible dross levels and maximum weldability. Nitrogen, meanwhile, will provide good cut quality, although it is usually used with air as a secondary gas. Water shields, on the other hand, will produce the best finish and edge quality.

Pilot arc

A pilot arc is an additional feature of a plasma cutter. It helps the torch start the arc without touching the metal, which extends the life of the consumable. It also cuts better and can be used to clean dross. It can be purchased separately. A pilot arc increases the efficiency of a plasma cutter, but it will add a few dollars to its price. A pilot arc is necessary for many applications, and you should invest in one before purchasing the machine.

Electrical circuit

The electrical circuit of a plasma cutter has three components: the power supply, arc starting circuit, and arc discharge. The power supply converts single phase AC line voltage into DC voltage, usually 200 to 400 volts, and controls the output current according to the type of material and thickness of the cut. The arc starting circuit starts an arc in the torch, which produces a high intensity ionized gas.
