CNC plasma cutters that are used infrequently can be purchased so that they are just capable of cutting the thickest material that needs cutting, but if the CNC plasma cutting machine, or manual cutting machine is required for longer periods of time, then it will need to offer more power output.Ĭomputer Numerical Control (CNC) means that the cutting process can be largely automated, and it is possible to ensure a precise cut as well as being able to easily change the shape, depth, and other details of the cut achieved.

In some instances, and most commonly with a CNC plasma cutter, the cutter will be on operation for longer periods of time, and this will affect the appropriate model to buy. The duty cycle is essentially the number of hours that the plasma CNC machine will be used without rest. This will help you to determine which is the best used plasma cutter for your needs, but it is only one consideration when looking at used plasma cutters for sale.ĬNC plasma cutter working precise Duty Cycle of CNC Plasma Cutter However, some models and some types of plasma cutter are more portable than others, and you should consider whether you will need to regularly move the cutter when it is in use. An air plasma cutting machine is typically a lot lighter than an oxyacetylene cutter, and it can be moved around the workshop, or even from one location to another with relative ease. Mobility is one of the advantages of a plasma cutting machine compared to other industrial cutting machines. Safety is important, however, because of the incredible heats that the arc nozzle will reach. The simplicity of operation, and the length of time that manufacturers have had to create inexpensive plasma cutting machines, means that a DIY plasma cutter is also a viable option – especially because of the number of portable models that can be easily stored until they are needed again. There are many makes and models currently on the market, and when used plasma cutters are also considered, this further expands the selections that are available to the buyer. Using a plasma cutter is a very simple process, and arguably the most difficult aspect is choosing the most appropriate plasma cutter machine for your requirements. Plasma cutter cutting sheet metal Using Plasma Cutters Used in any application where metals need to be cut quickly and efficiently, plasma cutters are available in a number of different forms and styles. This plasma is hot enough and moves quickly enough that it will not only cut metal but it will also blow the molten metal away. Simple and Effective Plasma Cutting MachinesĪ plasma cutter uses inert gas, through which an electric current is passed, creating plasma from some of the gas.
