PL-1 Plasma Torch Lifter

The PL-1 Plasma Torch Lifter combines plasma arc voltage monitoring with
a CNC closed loop positioning axis to greatly enhance plasma height control in
plasma cutting, resulting in a higher duty cycle and better cut quality. 

Coupled with the SureStop Collision Sensor if a collision occurs while cutting the magnet that holes the torch rigidly in place breaks free, and the process shuts off. The torch is protected from damage due to programming, obstructions on the cutting table and improper material positioning. Resetting after a collision takes only a few seconds.

The PL-1 torch lifter with height control is done through the CNC
software, resulting in less hardware and more reliability. The system is
flexible and allows the user to: program pierce height, retract distance, IHS
slowdown height, and conditional height freeze. Set initial height sensing via
ohmic position detection. Set the arc voltage range (50-300 volts DC).  Make servo loop adjustments for position and
velocity gain. Set semi or full automatic operation.

The PL-1 uses a 200W AC digital brushless servo motor and twin steel
guide ways with a precision ball screw to provide travel lengths of
4″-8″, depending on machine application. Moving elements are sealed
with protective steel strips and combine for tracking accuracy of +/- 0.3 arc
volts.
