Plasma Cutting FAQs
How to Use a Plasma Cutter (Beginner Guide)
To use a plasma cutter, connect the machine to power and compressed gas, attach the ground clamp to the workpiece, set the correct amperage for the material thickness, and guide the torch steadily along your cut line. Always follow proper safety procedures, including eye and hand protection. View our FlexCut Fundamental Videos to help you get started.
Can a Plasma Cutter Cut Aluminum?
Yes, a plasma cutter can cut aluminum. Because aluminum is electrically conductive, it responds well to plasma cutting. Proper amperage settings and clean, dry air or the correct gas supply help ensure smooth, accurate cuts.
How Does a Plasma Cutter Work?
A plasma cutter sends compressed gas through a small nozzle while an electrical arc turns that gas into plasma. The plasma becomes hot enough to melt metal, and the high-speed airflow blows the molten material away, creating a clean cut.
How Thick Can a Plasma Cutter Cut?
Cutting thickness depends on the machine’s amperage and power output. Lower-amperage units are designed for thinner materials, while higher-output systems can cut significantly thicker steel, aluminum, and stainless steel.
How Hot Is a Plasma Cutter?
The plasma arc inside a plasma cutter can reach temperatures of up to 20,000°C (about 36,000°F) or more. This extreme heat allows it to quickly melt through conductive metals while maintaining cutting precision.
Can a Plasma Cutter Cut Stainless Steel?
Yes, plasma cutters are highly effective at cutting stainless steel. The process produces fast cuts with minimal distortion, making it ideal for fabrication and industrial applications when settings are matched to material thickness. Check out our cutting guide for more information.
What Is a CNC Plasma Cutter?
A CNC plasma cutter combines plasma cutting technology with computer numerical control (CNC). This allows automated, highly precise cutting based on digital design files, making it ideal for production environments and complex shapes. The FlexCut 45, 65, 85, 105 and 125 are all compatible with CNC tables.
Does a Plasma Cutter Need Gas? What Gas Does It Use?
Yes, plasma cutters require gas to create the plasma arc. Many systems use compressed air, while others may use gases such as oxygen, nitrogen, or argon-hydrogen mixes depending on the material and application. Our FlexCut line has a quick connect compressed air hookup for simple set up.
How Much Does a Plasma Cutter Cost?
Plasma cutter pricing varies based on power, features, and intended use. The FlexCut line offers smaller, affordable units to larger industrial systems with higher output and advanced capabilities for all applications.
