State：
A、
The TORCH RETAINING CAP port on the Isolation-IHS plate connect to the
Torch Retaining Cap directly through pressing-wire hole(label: TORCH RETAINING
CAP).
B、 The WORK port on the Isolation-IHS plate connect to the material-shelf
directly through pressing-wire hole(label: WORK).
C、
GND must be linked with earth perfectly, the area of earth lead must
exceeds 4 mm².
D、 When the Plasma without HF arc, the WORK and GND can be linked with each
other directly.
E、 Connect the JPT2 on the controlling plate to PNP when you adopt the method
of Torch Retaining Cap IHS. As Figure 5 shows(JPT1 was selected the mode of
IHS ,JPT2 was selected the type of Proximity Switch )
JPT1

Figure 5：JPT1 Setting of Slip Wire
Working Process of Torch Retaining Cap IHS： After the high adjusting machine
receive the arc signal from the CNC system, the cutting torch come down immediately;
when the protection reach the steel plate, the high adjusting machine receive this signal
then control cutting torch to a setting height, when it finish, the high adjusting machine
control the Plasma arc automatically. You can adopt the touching-arc Plasma also HF arc
