Hypertherm HSD130 HySpeed Plasma - Manual (Page 58)

System description
General
The HySpeed HSD130 plasma system is designed to cut a wide range of thicknesses of mild steel, stainless steel
and aluminum.
Power supply
The power supply is a 130-amp, 150-VDC constant-current supply. It contains the circuitry to ignite a torch plus a heat
exchanger and a pump to cool the torch. The power supply has a discrete machine interface to provide communication
with a CNC controller.
Ignition console
The ignition console uses a spark-gap assembly. The ignition console converts 120 VAC control voltage from the
power supply into high-frequency and high-voltage pulses (9-10 kV) to break over the torch electrode-nozzle gap.
The high-voltage, high-frequency signal is coupled to the pilot arc lead.
Fuel-gas console (optional, see system diagram 2)
The fuel-gas console manages the selection and flow rate of incoming fuel-gases. The fuel-gas console includes a
regulator, solenoid valves, check valves and a pressure transducer. The fuel-gas console also houses a relay PC board
and a control PC board.
Off-valve
The off-valve consists of 3 solenoid valves, a manifold block and a wiring harness with connector. The assembly
interfaces with the power supply.
Torch
The torch can cut 12 mm mild steel at up to 2032 mm/min (1/2 inch at up to 80 ipm). The recommended production
cutting capability of the torch is 16 mm (5/8 inch). Maximum pierce capability is 25 mm (1 inch) for mild steel and
19 mm (3/4 inch) for stainless steel and aluminum. The maximum severance capability is 38 mm (1.5 inch) for mild steel
and 25 mm (1 inch) for stainless steel and aluminum.
