Use this CNC plasma settings calculator to estimate practical starting values for CNC plasma cutting. It gives you a structured baseline for amperage, travel speed, pierce height, cut height, pierce delay, and kerf estimate based on material type, thickness, and cut priority.
This tool is best used as a starting-point estimator, not a replacement for your machine manufacturer’s exact cut chart. Actual settings vary by plasma system, torch, consumables, air quality, table condition, and height control setup. Hypertherm’s published guidance and cut-chart materials both emphasize that cut charts, gas choice, and setup details strongly affect cut quality and results.
This CNC plasma settings calculator helps welders, fabricators, and table operators estimate practical starting values for amperage, speed, pierce height, cut height, and pierce delay.

Important Note For The Page
This calculator intentionally gives starting estimates, not fake precision. Manufacturer cut charts remain the most reliable source for final production settings, and published plasma guidance consistently stresses the importance of gas quality, consumables, cut height, and table setup in final cut quality.
