Welcome to our ultimate guide on plasma cutter thickness charts in 2023! If you are new to plasma cutting or looking to expand your knowledge, you’ve come to the right place. In this article, we will provide you with all the essential information you need to understand and utilize a plasma cutter thickness chart effectively.

What is a Plasma Cutter Thickness Chart?

A plasma cutter thickness chart is a valuable tool that helps you determine the appropriate cutting capacity of your plasma cutter for different materials and thicknesses. It provides a range of recommended settings, including amperage, cutting speed, and gas pressure, to achieve clean and precise cuts.

Understanding the Chart

The plasma cutter thickness chart typically consists of a table that lists different materials, such as steel, aluminum, and stainless steel, along with their respective thicknesses. Each material has a recommended range of amperage and cutting speed, ensuring optimal performance and quality.

Factors Affecting Cutting Thickness

Several factors can influence the cutting thickness of a plasma cutter. Some of the key factors include the power output of the plasma cutter, the type of gas used, the quality of the consumables, and the condition of the cutting torch. It is essential to consider these factors when referring to a plasma cutter thickness chart.

Choosing the Right Plasma Cutter

Selecting the right plasma cutter for your specific needs is crucial. The cutter’s power output and duty cycle should align with the thickness and volume of the materials you plan to cut. By referring to the plasma cutter thickness chart, you can ensure that your chosen machine is capable of handling the desired thicknesses effectively.

Using the Plasma Cutter Thickness Chart

Here’s a step-by-step guide on how to use a plasma cutter thickness chart:

Step 1: Identify the Material

Determine the material you want to cut, such as steel, aluminum, or stainless steel. Identify its thickness and locate it in the chart.

Step 2: Determine the Recommended Settings

Once you find the material and thickness in the chart, note the recommended amperage and cutting speed range. These settings will ensure optimal cutting performance.

Step 3: Set up Your Plasma Cutter

Based on the recommended settings, configure your plasma cutter accordingly. Adjust the amperage, cutting speed, and gas pressure to match the guidelines provided in the chart.

Step 4: Test Your Settings

Before starting your project, it is advisable to run a test cut on a scrap piece of the same material to ensure the settings are correct. Fine-tune as needed until you achieve the desired cut quality.


A plasma cutter thickness chart is an essential resource for anyone involved in plasma cutting. By understanding the chart and following the guidelines, you can achieve accurate and efficient cuts for a wide range of materials. Remember to choose the right plasma cutter for your specific needs and always refer to the chart for optimal settings. Happy cutting!
