PL-1 Plasma Torch Lifter

The MG PL-1 torch lifter combines plasma arc voltage monitoring with a CNC closed loop positioning axis to greatly enhance plasma height control. As accurate height control is very important in plasma cutting, this combination provides a higher duty cycle and better cut quality. The PL-1 torch lifter is available on all Precision and General Fabrication machine models.

The PL-1 torch lifter 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.

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 four or ten inches, depending on machine application. Moving elements are sealed with protective steel strips and combine for tracking accuracy of +/- 0.3 arc volts.

Key Features:

• 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
