ORDERING PROCEDURE
CUSTOMIZED ORDERING FOR HD-3070 w/AUTOMATIC
GAS CONSOLE
1 SPECIFY THE POWER SUPPLY
The HD3070 power supply houses a 100-amp, 15kw chopper power supply which produces a
constant current DC output variable from 15 to 100 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
recirculating cooling system to cool the torch. The power supply interconnects with the 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.
2 ORDER THE AUTOMATIC GAS CONSOLE
The gas console is designed to be mounted on the power supply. The unit interfaces with the
power supply, torch off-valve assembly, cutting machine interface and the supply gases. The
gas console must be located within 100 feet (30 m) of the torch off-valve assembly and 150 feet
(46 m) of the cutting machine interface.
• Order the gas console.
3 ORDER 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 RHF
console to be installed at a distance of up to 125 feet (38 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.
Check the mounting holes and weight of the console in the
Specifications section to determine
where it can best be attached.
4 SPECIFY THE LEADS BETWEEN THE POWER SUPPLY AND THE
RHF CONSOLE
The lead set from the power supply to the RHF console consists of five components:
a pilot arc cable, a #4 negative lead cable, a cooling supply hose, a cooling return hose, and
a control cable.
• Based on the distance (the path that the leads will have to run) between the power supply
and the remote high-frequency console, order the appropriate lead package.
