How A Plasma Cutter Works – Advantages and Tips

Have you ever asked yourself, “How does a plasma cutter work?” Well, you may not be the only one. 

As CNC machines gain popularity, you’ll find more of these amazing machines making their way into homes and warehouses across the nation. If you’re looking to make room for a CNC plasma cutter yourself, you may want to learn more about what makes these machines work and how to use them the most efficiently. 

In this article, we’ll look at the functions of these machines and some tips so you’re ready to tackle your projects. 

How Does a Plasma Cutter Work Step by Step

CNC plasma machine for beginners

Before you decide on a machine, you must do your due diligence to understand how it works and what you need from it. There isn’t anything too complex about how a CNC plasma machine works when you get the hang of it, but to a beginner, it can feel like drinking from a fire hose — but not with ShopSabre. 

We’ll break it down. 

The Science Behind How a Plasma Cutter Works

A CNC plasma cutter works by forcing gas (nitrogen, argon) or compressed air (shop air, oxygen) at high speeds through a nozzle. 

Next, an electric arc is introduced to the gas, creating ionized gas — or plasma — the fourth state of matter. 

The restricted opening on the nozzle causes the plasma to squeeze through at high speeds, which gives the plasma the power to cut through metals. 

The gas is also directed around the perimeter of the cutting area, shielding the cut. 

Steps To Using a Plasma Cutter

When getting ready to use a plasma cutter, the steps would look something like this, though they depend on the specific machine:

  1. Choose your work location.
  2. Plug in the machine
  3. Connect the external air to the plasma cutter
  4. Turn on the air
  5. Attach the ground clamp
  6. Turn on the machine
  7. Set the current
  8. Cut the metal

In the end, you’ll generally want to power down the machine, turn off the air, and wind up all the hoses used.

Tips For Finding The Right Plasma Cutter

Hopefully, asking “How does a CNC plasma cutter work” has now turned into asking what the best CNC plasma cutter for you is.

When it comes to picking a great plasma cutter, we’ll let you in on a few tips: go for resources and software, speed, and ease of use, and don’t forget to account for what sheet size working area you need.

How Does a CNC Plasma Cutter Work to Your Advantage?

 

You may need to weigh the pros of a CNC plasma cutter before deciding to invest in one. A plasma cutter is as versatile as you can get when it comes to working with different materials and leads to other benefits like: 

  • Less Material Waste: Plasma tables eliminate the material waste and financial loss you can experience when using alternatives like handheld plasma cutters. The precise cuts these tables offer ensure you get the most from your materials. 
  • Quick, Accurate Cuts: CNC controllers and software on machines like the Crossfire XR expedite cuts and ensure they are done precisely. Other features like the Automatic Torch Height help replicate these perfect cuts every time.
  • Increased Productivity: Think of how quickly you can work with a CNC plasma machine. Less time spent on wasting material and trying to perfect a cut with a handheld cutter means more time spent creating.
  • Reduced Labor Costs: Sometimes, hobbies turn into profitable opportunities. When you invest in a CNC machine, you increase your productivity, quality, and your chances of a nice profit margin should you decide to sell your product. 

There’s more to a great plasma machine than the look. These benefits you get from ShopSabre’s plasma cutters are crucial in making your work more rewarding and helping you level up your skills.
