General Definitions:
AHC Arc voltage Height Control
Arc Voltage Voltage measurement between the electrode and the work piece which is used to control
the torch to work distance during cutting.
Cutting Height Distance between the plasma torch and the work piece during cutting.
Ignition Height Torch to work distance during arc transfer. This setting is typically lower when using a THC
with elevation height in order to increase transfer reliability.
Pierce Height Distance from Pierce Ignition Height that the torch raises to in order to prevent torch damage
during plate piercing.
Lead-in Time Time following arc transfer that the torch remains at Pierce or Elevation Height. This is often
longer than the CNC Motion Delay in order to allow the torch to clear the pierce puddle.
Piercing Time Time following arc transfer to allow the arc to piece through the plate before the table XY
motion starts.
AHC Delay Often called AVC delay, this is time starting when torch is moved to Cut Height until THC
starts controlling height to the sampled arc voltage.
Speed Recommended cut speed based on the material thickness, torch parts and gas combination
used.
Kerf The width of material removed during the cut.
