1、Brief Introduction
1.1、Product Model：
XPTHC-100
1.2、Chinese Name：
弧压高度控制器
1.3、Applied Scope：
Apply to most of the import machine or state-owned machine because of the high
controlling of Plasma incision machine with the feature of constant current or the
feature of constant current in certain voltage scope.
1.4、 Working Principle：
The working principle of XPTHC-100 Plasma controller is using the constant
current of the Plasma power to attach the high controlling for the incision cutting torch
through checking the change of voltage to check the high changing of cutting torch in the
incision process.
1.5、Basic Principle：
A、 Automatic IHS：
Divide into checking method of Torch Retaining Cap IHS and Proximity
Switch IHS checking method which has NPN and PNP two types.
B、 Anti-bump of Torch：
After cutting torch bumps into the steel plate in any condition, when examines the
electric circuit movement, will make the cutting torch promote to height.
C、 Automatic High Controlling.
D、 Display the Monitoring Function Of the given arc voltage and the actual arc voltage:
Arc voltage table demonstrates the given arc voltage before the Plasma arc
on, and Arc voltage table demonstrates the actual arc voltage after the process
of getting up the arc and perforation time delay .
E、 All the function of above-water incision and under-water incision of automatic
IHS method:The first invention from our company is under-water incision of Torch
Retaining Cap. The normal order has no special function about this except our
clients request it.
The cutting torch lifts and the Plasma gets up the arc when we have
no IHS: When we don’t use the automatic IHS function we can make the cutting
torch reach the steel plate directly; When we carry on the arc operation,
the cutting torch can promote to be separated from the steel plate
