Product Description
1.Product name and model
name: Plasma arc voltage height controller PTHC-200 series,
model: PTHC-200DC
2.Working principle and scope of application
Suitable for controlling the cutting torch height of plasma cutting machines with constant current characteristics or within a certain voltage range, suitable for most imported or domestic models.
3.The principle of a plasma arc voltage regulator is to use the basic constant current characteristics of a plasma power source to detect changes in plasma arc voltage to determine the height of the cutting torch during the plasma cutting process, and to achieve automatic height control of the cutting torch.

Product Features
1. Operation transmission method: detect arc voltage enable, complete perforation output;
2. Dynamic perforation function: cutting thick plates effectively improves the service life of vulnerable parts;
3. Partial pressure ratio: 100:1 (default);
4. Accuracy: ± 1V to ± 2V, related to the user's motor response speed and the flexibility of the elevator structure;
5. Adaptable cutting torch lifting speed: 1 meter/minute to 4 meters/minute (please contact the supplier if exceeding this speed);
6. Setting the arc voltage range: It can be modified according to different application scenarios, and it is between 35V and 250V during plasma cutting,
7. Overload protection method: PWM speed regulation, current feedback;Maximum cutting tracking test speed: 10000mm/minute (related to the setting of the starting voltage, speed, and sensitivity of the user's lifting body motor).
Product Application
PTHC-200DC is our new stand alone THC in 2013, comparing to old XPTHCs,
new features as follow:
1.Support Torch retaining cap IHS or Nozzle Contact (ohmic contact) IHS with any HF plasma…..Great anti-interference improvement.
2.PTHC has much higher accuracy than old XPTHCs, standard accuracy is 1V, enough to support HD plasmas. max support 12000mm/min cutting speed.
3.Support Dynamic pierce, collision output to CNC.
