This is a process that uses a high-velocity jet of ionized gas, or plasma, to cut through metal like butter. The plasma is created by passing an electrical current through a gas such as nitrogen, oxygen, or argon. With temperatures reaching up to 30,000 degrees Fahrenheit, it’s no wonder why plasma cutting is such an efficient and popular method for cutting various metals including steel, aluminum, and copper.
But don’t let the simplicity of the tools fool you. Plasma cutting can be dangerous if proper safety precautions are not followed. The high temperature of the plasma arc can cause burns or start fires, and the metal being cut can produce hazardous fumes and dust. That’s why it’s essential to wear appropriate personal protective equipment (PPE) when performing plasma cutting, including eye protection and respiratory protection.
Speaking of eye protection, let me share some important tips with you. During plasma cutting, the bright and concentrated arc emits ultraviolet (UV) and infrared (IR) radiation that can be harmful to your eyesight. That’s why it’s crucial to wear a welding helmet with the right shade lens to protect your eyes. But how do you know which shade lens is required for plasma cutting?
For low-amperage plasma cutters (under 40 amps), a shade 5 or 6 lens will suffice. For amperages between 40 and 100, a shade 8 or 9 lens should be used. For higher amperages (over 100), you will need to use a shade 10-13 lens. Think of it like sunscreen for your eyes. Just like you wouldn’t go out into the sun without proper protection, you shouldn’t perform plasma cutting without proper eye protection.
But that’s not all. Choosing the right shade lens is just one aspect of protecting your eyesight during plasma cutting. You also need to consider other factors when choosing a welding helmet, such as a good fit and comfortable headgear, as well as a clear view of the work area that allows you to see what you’re cutting without strain or discomfort.
Plasma cutting is a fascinating process that has revolutionized metal fabrication, automotive repair, and industrial construction. But it’s crucial to remember that safety always comes first.
Types of Plasma Cutters

Knowing the different types of plasma cutters is essential in determining the appropriate shade lens required for plasma cutting. Think of it like choosing the right pair of shades depending on where you’re going and what you’ll be doing.
The shade lens requirement may vary depending on several factors such as the type of material being cut and its thickness, so make sure you do your research before starting your next project.
Understanding the Light Intensity Generated by Plasma Cutting
As you step into your workshop and fire up your plasma cutting machine, it’s essential to remember that the intense light generated by this powerful tool can be harmful to your eyes if you don’t take the necessary precautions. Just like a superhero donning a mask, you need to protect yourself with a shade lens and personal protective equipment (PPE) before unleashing your plasma cutting powers.
The light intensity generated by plasma cutting is comparable to welding, but much more concentrated. This bright light can cause flash burns, which are painful and can even lead to vision problems. That’s why it’s crucial to wear a shade lens when using a plasma cutter, as the lens will protect your eyes from harm.
The shade lens required for plasma cutting depends on the amperage of your machine. The higher the amperage, the darker the shade lens required. For machines rated under 40 amps, a shade lens of 5 or 6 is recommended. Machines rated between 40 and 80 amps require a shade lens of 8 or higher, while machines rated over 80 amps require a shade lens of at least 10.
However, choosing a shade lens that’s too dark can be just as harmful as not wearing one at all. It can cause eye strain and make it challenging to see what you’re working on.
So, it’s essential to choose the appropriate shade lens that corresponds with the amperage of your plasma cutter.
Choosing the Right Shade Lens for Your Welding Helmet
When it comes to plasma cutting, safety should always be your top priority. One of the most critical steps you can take to protect yourself is choosing the right shade lens for your welding helmet. With so many options available, it can be challenging to determine which one is right for you. But fear not, we’ve got you covered.
First and foremost, it’s important to understand that plasma cutting emits intense light and radiation that can be harmful to your eyes if not protected properly. This is why selecting the right shade lens is crucial for your safety. The American Welding Society (AWS) recommends a minimum shade lens rating of 8 for plasma cutting. This rating will block out at least 90% of the harmful radiation emitted during the process. However, some experts suggest going for a rating of 10 or higher for added protection.
When choosing a shade lens, you’ll also need to consider the material you’re cutting. Thicker materials may require a higher rating than thinner ones.
