Description
General
The HD4070 is a fully automated 200 amp HyDefinition plasma cutting/marking system that requires minimal input
and adjustment by the operator. Using the HD4070 display touch screen (or CNC), the operator enters the material
and thickness to be cut. The HD4070 system automatically selects and adjusts the power and gas required to
optimize cutting, including amperage, gas type and gas flow rates.
Power Supply
The power supply houses two 100-amp, 15 kHz choppers to produce up to 200A of constant current DC output.
The HD4070 power supply provides the torch the energy to cut 1/2" (12.7 mm) mild steel at up to 90 ipm
(2286 mm/min.).
Machine Torch
The machine torch can cut 1/2 inch (12.7mm) mild steel at 90 ipm (2286 mm/min.). The maximum production
cutting capability of the torch is 1 inch (25 mm). To achieve consumable long life, all cuts must begin and end
on the plate surface.
Off-Valve Assembly
The off-valve assembly consists of 5 solenoid valves, a manifold block and a wiring harness with connector. The
assembly interfaces with the machine torch, the ignition console and the gas console.
Gas Console
The gas console manages all incoming gasses for selection and flow rates and is controlled by the HD4070 power
supply. The gas console includes motor valves, solenoid valves, check valves and pressure trans-ducers all
mounted on a single manifold assembly. The manifold significantly reduces gas leaks by eliminating the use of
flexible hose. The gas console also houses 2 relay PC boards and a control PC board.
Ignition Console
The ignition console generates a high voltage, high frequency signal and couples it to the cathode lead and pilot
arc lead. The ignition console is fully electronic eliminating the need for periodic maintenance.
