1-2 HT4001
INTRODUCTION
Hypertherm’s HT4001 system is designed as a machine-mounted, water-injection plasma
cutting system for production cutting carbon steel, stainless steel and aluminum from gauge
to three-inch (75 mm) thick when configured with a slave power supply and using nitrogen as
the plasma gas. A micro-controller on the HT4001 power supply control board helps to
provide extended life for the torch consumable parts in the oxygen cutting mode. To optimize
consumable life, all cuts must begin and end on the plate surface when cutting with
oxygen as the plasma gas; this allows for the proper control of gases and DC current to
extend the life of the torch nozzle and electrode.
The HT4001 system provides the user with the capability of locating the power supply a
maximum distance of 200 feet (60 m) from the torch. This is accomplished by adding a
Remote High Frequency (RHF) Console.
The HT4001 configured without a slave power supply provides continuously variable current
output from 100 to 400 amps for optimum performance on all thicknesses of metal up to two-
inch (50 mm) thick. Three nozzle sizes are provided to produce high-quality cuts throughout
the range of cut thicknesses.
The HT4001 configured with a slave power supply provides continuously variable current
output from 100 to 750 amps for optimum performance on all thicknesses of metal. This
allows the operator wide variations in cutting speeds on the same thickness of metal. Five
nozzle sizes are provided to produce high-quality cuts throughout its range of cut thick-
nesses.
The HT4001 can be configured for oxygen or nitrogen cutting. Nitrogen will cut stainless
steel, aluminum, carbon steel and other non-ferrous materials. Oxygen will cut mild (carbon)
steel.
