Ordering Procedure
Specify the Power Supply
The HD1070 power supply houses a 70-amp, 15kw chopper power supply which produces a constant
current DC output variable from 15 to 70 amps. It contains a microprocessor control PC board which
regulates all of the plasma system functions: start sequence, machine interface functions, gas and cut
parameters, and off sequence. The power supply also houses the recirculator cooling system to cool the
torch. The timer-counter unit and a 3-foot (1 m) timer-counter cable are included in the power supply
package. The power supply interconnects with the timer-counter, RHF console, machine interface, gas
console, and the workpiece.
• Determine the placement of the power supply (supplies) and input line voltage available at the site and
order the appropriate power supply. See Specifications for details on power supply dimensions and
weight.
Specify the Timer-Counter Cable
• If the timer-counter will be located farther than 3 feet (1 m) from the power supply, order different length
cable.
Specify the RHF Console
The RHF console houses the high-frequency starting circuit which is needed to initiate the torch. The high-
frequency starting circuit permits more effective RF shielding and allows the power supply to be installed
at a distance of up to 100 feet (30 m) from the power supply and 40 feet (12 m) from the torch. A door
interlock switch and a cathode manifold are also located in the RHF console.
• Determine approximately where the console will be mounted on the cutting machine and note the distance
from the power supply and the torch. Check the mounting holes and weight of the console in the
Specifications section to determine where it can best be attached.
