Hypertherm HD3070 w/ Automatic Gas - Manual (Page 5)

1-2 HD3070 w/Automatic Gas Console
INTRODUCTION
Hypertherm’s HD3070 HyDefinition® plasma cutting system 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 HD3070 system consists of a power supply,
remote high frequency (RHF) console, gas console, off-valve assembly and torch. Optional
units include a timer-counter and a remote current control.
The HD3070 can be configured for either robotic applications or X-Y cutting tables. To
accommodate the different needs of these two types of systems, two different torches are
offered.
TORCHES
PAC184
If ordering for a robotic system, the PAC184 torch with 45
°
quick disconnect is recom-
mended. This torch, with a pointed front end, is designed to cut in a robotic environment.
PAC186
The PAC186 torch with the straight quick disconnect is more suitable for X-Y cutting tables.
A unique feature to the PAC184 and PAC186 torches is that the torch bodies, quick discon-
nects and mounting sleeves are all interchangeable.
CUTTING MACHINES
If cutting on an X-Y machine, 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 in. Initial height
sensing (IHS) for plate piercing must also be accurate and repeatable to ensure long
consumable life.
Hypertherm recommends HD3070 units be installed on new, high-precision X-Y machines.
For robotic and hard tooling applications, any system that is laser compatible will generally
perform well with the HD3070 system.
