The Science of Plasma Cutting
It is important to understand how the system operates to avoid potential problems and to assist in diagnosing operational errors or failures.
Plasma cutting is a science as well as an art. To make good cuts it’s necessary to have a good understanding of your torch and materials, the right settings on your torch and CNC system, and consistent operation. While plasma cutting systems can run with constant height fixtures, warping of the materials or inaccurate fixturing can create variations in the distance from the torch tip to the material.
These variations can cause the kerf of the cut to change during the cut, or even for the torch to extinguish. The torch height controller gives you consistency in your torch height by maintaining the distance between the material and the torch tip.
