Vital Systems ArcPro V2 Plasma Control offers a high-performace industrial torch height control system.

ArcPro V2 reads the torch tip voltage through a 0-10V isolated analog input on the motion controller. This reading is used to control the torch height motion in a real-time process.

ArcPro V2 lets the operator easily switch the Plasma cutting parameters based on the material being worked on just by changing the Tool number in mach4.

ArcPro V2 implements voltage Anti-Dive and feedrate Anti-Dive Protection features. 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. To avoid diving in this situation, the Feedrate 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 locked.

When the torch tip moves over a hole during cutting, the plasma tip voltage increases. The response from the THC is to lower the torch. To avoid diving into existing holes, the Voltage Anti-Dive works by continuously sampling the tip voltage. When the tip voltage exceeds the threshold value within a period of 50 millisec time slot, Anti-Dive is engaged and the Z-Axis motion is locked. When the tip-voltage comes back to previous cut voltage, the Z motion is unlocked.

The ArcPro V2 THC Screen for Mach4 allows the user to enter all parameters necessary for Plasma operation.
