ORDERING PROCEDURE
Customized Ordering for HD3070 with Manual Gas Console
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.
Order the Manual Gas Console
The gas console interfaces with the power supply, torch off-valve assembly and the supply gases. The gas
console must be located within 100 feet (30 m) of the torch off-valve assembly.
• Order the gas console.
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.
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.
