Plasma Cutters Automatically Maintain Torch Height

Techno CNC Systems’ HPLC plasma cutter series offers machines for small- to mid-sized shops and classrooms. The series includes machines in stock sizes of 4 × 4, 4 × 8 and 5 × 10 ft., with multiple available torch options. The systems are capable of high-speed cutting ranging to 800 ipm and can cut steel as thick as 1".

The plasma cutters are equipped with a control system powered by brushless micro-stepper motors that are said to require no maintenance and deliver continuous high-speed performance. The heavy-duty all-steel construction includes precision rack-and-pinion drives on the X and Y axes, and a ballscrew on the Z axis for precise torch positioning. The machines’ automatic CNC torch height control maintains a constant arch voltage and includes magnetic torch breakaway with Z-axis auto retract. A steel V-grid downdraft and a water-spray nozzle help reduce smoke. The handheld control is compatible with G and M codes, and the systems function independently of a PC. Files are transferred via a USB memory stick. Electronics are housed in a double-door industrial cabinet that also serves as a worktable for the required tools.
