Understand Your Plasma Cutting Needs
Before selecting a plasma cutter, start by knowing what applications you will use it for:
- Material Type and Thickness: Match the machine’s capacity to the thickness of material you’ll cut most often. More amperage generally allows thicker cuts.
- Frequency of Use: Light hobby use differs greatly from heavy industrial production. Consider machines built for continuous duty cycles if you work long hours.
Categories of Plasma Cutting Machines
Plasma cutting machines fall into broad price and performance groups:
- Budget Machines (Under $15,000): Good for hobbyists. Limited features and support
- Mid-Range Machines ($15,000–$30,000): Reliable for frequent commercial use.
- Industrial Machines ($30,000+): High power and uptime for daily industrial workloads.
Key CNC Plasma Table Features to Evaluate
When comparing plasma cutters, consider these key specifications:
Power and Amperage
Higher amperage delivers greater cut capacity. For example:
- 45A can cut up to ~3/8″ mild steel.
- 85A+ handles thicker material with better precision.
Duty Cycle
Duty cycle indicates how long a machine can run before needing to cool. A higher duty cycle is essential for longer continuous cuts.
Ignition Type
Modern units use pilot arc ignition for smoother starting and longer consumable life.
Power Supply Compatibility
Know if the machine requires:
- 120/240V single-phase
- Three-phase power for heavy industrial machines

Questions and Answers — Choosing the Right Plasma Cutter
Base it on the material thickness you cut most. Lower amperage suits thin sheet metal; higher amperage is needed for thick structural steel.
It tells you how long the cutter can run continuously. A higher duty cycle means less downtime.
A pilot arc lets the plasma cutting machine start the cut without direct contact, reducing wear and improving reliability.
Yes, many mid-range units work on 240V single-phase power and remain portable.
Balance cost with the features you need. Underinvesting on features like height control can increase long-term costs.
