Plasma cutting tips
The following reference guide offers several solutions to help improve cut quality.
Consider the following factors when evaluating plasma cut quality:
 Type of machine (example: XY table, punch press)
 Plasma cutting system (example: plasma system, torch, consumables)
 Motion control device (example: CNC, torch height control)
 Process variables (example: cutting speed, gas pressures, flow rates)
 External variables (example: material variability, gas purity, operator experience)
All of these factors can affect the appearance of a cut.

Angularity
Positive cut angle: More material is removed from the top of the cut surface than from the bottom.
Negative cut angle: More material is removed from the bottom of the cut surface than from the top.
