Arc Voltage Plasma Controller ARC Torch Height Controller THC for CNC Plasma Cutting

Arc Voltage Plasma Controller ARC Torch Height Controller THC for CNC Plasma Cutting Description

It 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 as the setting arc when at beginning the AUTO status. It's suitable for some small plasma.
4. High Sensitivity:adjusting the THC's sensitivity, could realize the arc volt change 1V, the arc voltage output will change 1.5V-4V, and don't occur the vibration. So the lifter's start voltage is closed related to the THC's sensitivity, Our lifter's start voltage is 1.5V-2V.
6. Good stable :XPTHC-4 has 5 sets isolation power inside, to realize the I/O isolation; sampling arc volt isolation; drive isolation; and control isolation.
It is with full function of the Stand alone Arc Voltage Torch Height Controller. But as it's with small body, the motor of the lifter should be less than 20W on the portable CNC cutting machine, light gantry machine and small bench type machine etc.

Specification:
Name:Arc voltage torch height controller ( THC );
Input Power:AC24V10 %, 50Hz/60Hz or DC24V20 %;
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 range: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 ).

SAFETY:
- DO NOT open cabinet of THC unless trained technician.
- DO NOT adjust the sealed resister.
- Turn off Powersupply if when THC is unused.
- DO NOT put liquid on THC.
- Attention Anti-dust work, DO NOT let metal dust into THC.

Installation Note:
- Power supply: AC 24V or DC 24V.
- Please offer the enough power supply : usually , 25W motor , the current couldn't beless than 3A , the AC24V transformer couldn't be less than 50W.
Power supply = 2*motor's power + 10W.
- GND Must follow THC instruction, GND resister4.
- UP / DOWN on THC must be same to Z-axis Lifter.
- To avoid interference, follow cables please use shield cable ( connection between CNC controller and THC, to motor , to voltage divider , to IHS card ) . especially the cable from THC to voltage divider , please use shield twisted pair cable , and shield net connected at THC side.
- The plasma raw arc couldn't connect to the THC directly , must connect to the voltage divider correctly.

Package Included:
1 Set X Plasma Torch Height Controller(as the picture shows )
