Introduction
Hypertherm’s HyDefinition™ plasma cutting system (HD1070) is a precision cutting dual gas machine-torch
system. The microprocessor-controlled system helps to provide extended life for the torch consumables parts. To
achieve consumable long life, all cuts must begin and end on the plate surface; this allows for the proper
ramping of gases and DC current to extend the life of the nozzle and electrode. The HD1070 system consists of a
power supply, remote high frequency (RHF) console, gas console, and torch.
The HD1070 system can be configured for oxygen or air cutting. The power supply provides a selectable current
output from 15 to 70 amps for optimum performance on cutting most metals from gauge to 3/8-inch (9.5 mm) thick.
This allows the operator wide variations in cutting speeds on the same thickness of metal.
Air is used as the plasma gas for cutting stainless steel at 30, 50 and 70 amps, and aluminum at 70 amps. Oxygen
is used as the plasma gas for cutting mild steel at 15, 30 and 70 amps.
An oxygen-nitrogen mixture is used as the shield gas for cutting mild steel at 15, 30 and 70 amps. A methane-air
mixture is used as the shield gas for cutting stainless steel at 70 amps. Methane is used as the shield gas for
cutting aluminum at 70 amps, and air is used as the shield gas for cutting stainless steel at 50 amps.
Cutting Machines
IIn order to produce the highest-quality cut possible, it is extremely critical that the torch drive system has very
accurate vibration-free control of the X, Y, and Z axes. Placing a precision-cutting plasma system on a cutting
machine with poor positioning or poor contouring tolerance, or with inadequate acceleration and deceleration
characteristics will clearly show the effects on the cut face. The Z-axis of the cutting machine must be controlled
to +/-.005". Initial height sensing (IHS) for plate piercing must also be accurate and repeatable to ensure long
consumable life.
Hypertherm recommends HD1070 units be installed on new, high-precision X-Y machines built by MG Industries,
Advanced Kiffer Systems, Lockformer, Advanced Machinery and Koike Aronson. For robotic and hard tooling
applications, any system that is laser compatible will generally perform well with the HD1070 system.
