、Brief Info
1.1 、Product name and model
Arc voltage torch height controller ( THC)
Model: XPTHC-4
1.2、Application
XPTHC-4 supports almost all plasma cutters on market like Hypertherm, Thermal Dynamics…
And it supports all CNC cutting controllers on market like Hypertherm, Burny industrial level controllers
or Mach3 such DIY controllers, because XPTHC-4 can start Auto Height control with or without Auto
enable signal from CNC. But with Auto enable/disable signal from CNC, THC would work better.
1.3 、Basic Parameter and Feature
Input Power：AC24V+10%，50Hz/60Hz or DC24V±20%;
Motor：DC24V DC motor;
Motor Drive：PWM;
Output current：0.1A-1.8A;
Load capacity：Max 20W；
Working temperature
：-10∽60℃；
IHS：Switch IHS & Proximity switch IHS； Do Not support the retaining cap HIS
Work way: check the arc enable output, 200mA optical coupler OC door output
Voltage Divide ratio:
50:1 non-isolation on voltage divider; 1:1 isolation inside of THC
Control accuracy
：
∽
±1V ±3V，depends on the motor and lifter of user.
The speed of lifting
：1000mm/min ∽ 3000mm/min
(Contact the supplier if it exceeds the range
of speed）
；
Arc Voltage rang：50V∽250V，
Over protection：PWM adjusting, current feedback；
Max speed test：12000mm/min（ it’s related to the setting on the lifter’s speed and
motor’s start voltage and sensitivity)
XPTHC-4 is the newest design THC, special for portable CNC cutting machine and small
bench type machine, with 32 ARM processors, and analogous circuit height control together.
Feature:
1, installation: user could install the THC’s operation panel on the work interface, or install
it at the convenient operation place. Install the main body at a suitable station.
2, height controller: could change the auto cutting height at any time
3, two modes of the setting arc volt:
A, Setting arc volt mode: set the setting arc volt on the operation panel, let the THC
work on the setting arc volt status. It’s the traditional work way.
B, sampling arc volt is the setting arc volt: when the THC control the torch finish the HIS
and plasma start, and CNC controller open the AUTO signal to THC, and THC will test the arc
