A CNC plasma cutter is a machine that uses a plasma torch to cut metal. The plasma torch is a type of cutting torch that uses a high-energy stream of ionized gas to melt and vaporize the metal. The CNC plasma cutter is controlled by a computer, which allows it to cut intricate shapes and patterns in metal.

CNC plasma cutters are used in a variety of industries, including:

  • Manufacturing: CNC plasma cutters are used to cut metal parts for a variety of products, including cars, appliances, and machinery.
  • Construction: CNC plasma cutters are used to cut metal beams and other structural components for buildings and other structures.
  • Signmaking: CNC plasma cutters are used to cut metal signs and other advertising materials.
  • Hobbyists: CNC plasma cutters are also popular among hobbyists, who use them to create a variety of metal projects.

CNC plasma cutters are a versatile and powerful tool that can be used for a variety of applications. They are relatively easy to use and can be operated by people with basic training. CNC plasma cutters are a valuable asset for any business or individual that needs to cut metal.

Here are some of the benefits of using a CNC plasma cutter:

  • Accuracy: CNC plasma cutters can cut metal with great accuracy. This is important for businesses that need to cut metal parts to precise specifications.
  • Speed: CNC plasma cutters can cut metal very quickly. This can save businesses time and money.
  • Versatility: CNC plasma cutters can cut a variety of metals, including steel, aluminum, and stainless steel. This makes them a versatile tool for a variety of applications.
  • Durability: CNC plasma cutters are built to last. They can withstand the rigors of daily use in a manufacturing or construction environment.
  • Cost-effectiveness: CNC plasma cutters are a cost-effective way to cut metal. They can save businesses money in the long run by reducing the amount of time and material that is wasted.

If you are looking for a versatile, accurate, and cost-effective way to cut metal, then a CNC plasma cutter is the right choice for you.

Plasma Cutter Requirements:
Cut50L LF Blow Back Start

Unfortunately, not all plasma cutters are suitable for hobbyist CNC tables. Plasma cutters that rely on a high frequency (HF) AC voltage to start the plasma stream radiate a significant amount of electromagnetic interference (EMI). Proper grounding and an industrial control is needed to avoid erratic behavior of the machine when using a HF plasma cutter.

Less noisy plasma cutters use a technology known as “blowback" or "moving" start, where a moveable, spring-loaded electrode and a DC spark start the plasma stream. Blowback start plasma cutters produce significantly less EMI and can be used around CNC microcontrollers and electronics that have not been engineered to withstand high levels of electrical noise. Blowback start is a more complex way to initiate the plasma stream, and there is a significant upcharge when it comes to torches that use this technology and their consumables. In my opinion, this is money well spent because in my CNC plasma cutter video I spent a lot of time pulling my hair out trying to get a high frequency plasma cutter to work with my table. I have compiled a list of plasma cutters below that use this low frequency technology and should work with your DIY plasma cutter build.

More Info or Purchase


CNC plasma cutting can be operated as a job shop for local hobbyists or businesses.  Products that come out of plasma cutters are of high mechanical ability.  Entry level cost is in the two to four thousand dollar range.   E-Machine Shop X-ometry     There are electrical  noise issues with plasma making it more difficult to set up. Consumables are less in need of replacement as often as CNC's parts. CNC has a bit of a learning curve. You can download and emulator software like CAMotics to facilitate learning your way around before investing in a machine. Highly recomended as that you will be able to tell in short order just how much machine you might be interested in commaniding.
