Vital Systems ArcPro Plasma Control offers a tight control-loop integration with most THC devices available in the market.
ArcPro uses the up/Down control signals from the THC device to command the Z motion in a real-time process inside the motion controller.
Anti-Dive Protection: ArcPro implements the Anti-Dive Protection feature. Anti-Dive prevents the THC from dropping the torch into a cut hole, diving into corners, or diving at the end of a cut. When the XY cutting speed slows down, the plasma tip voltage increases. The response from the THC is to lower the torch. Anti-Dive works by setting a feedrate set point. When the cutting feedrate drops below the set value, Anti-Dive is engaged and the Z-Axis motion is disabled.
The ArcPro THC Screen for Mach4 allows the user to enter all parameters necessary for Plasma operation.
Example of THC device with Up/Down Signals is THC150 from http://eagleplasma.com ( User Manual THC150 )
