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, especially when moving at corners, the torch will continue to remove material and cause the tip voltage to rise. 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.
