PTHC-II Plasma Arc Voltage Height Controller

PTHC-II plasma arc voltage height controller is equipped with constant current plasma . During cutting course, the current always equals the given current. And the cutting arc voltage will be changed with the fixed speed being the height of torch changing. When the distance gets farther，the arc voltage increases; On opposite, the arc voltage will decrease. PTHC-II plasma arc voltage height controller will inspect the voltage change, then control the distance between cutting torch and material via the lift motor. So that the arc voltage is fixed, the same is the height of cutting torch.
Generally, the instruction will list all the cutting parameters for some type of plasma. The user can refer to these parameters. Adjust the voltage in arc voltage height controller to match the selected current.
The torch height will keep constant under regular speed.In fact,the user should set the arc voltage according to the height of the cutting torch.
In the status of automation ,the arc voltage more high,then the height of the cutting torch more high.

Product Description

The persons who developed PTHC-II arc voltage height controller have many years’ experience in developing and using. They sum up all the characteristics of Arc voltage height controllers which are made in China and Overseas.

1、PTHC-Ⅱ takes the high capability microprocessor as the core. Use of big screen chart and character LCD; American AD company high voltage isolating amplifier；PWM control transfer.

2、Divided voltage ratio matching input:

PTHC-Ⅱ will inspect the input voltage with divided voltage ratio

100:1 We will provide the isolated divided voltage controller ratio

100:1 when buying this product. At the meantime, an isolated divided voltage controller is assembled in the controller to isolate the Two times.

If the plasma controller has the divided voltage controller, the height controller can adjust the inner parameters to match it.

3、The Given Arc voltage and actual Voltage Shown together: The give arc voltage can be adjusted on the control board as per the actual parameter. The actual voltage will be shown automatically

after Arc-on, and kept on dynamic tracking status. On automatically, the error between Actual arc voltage and given arc voltage should be in the range of accuracy.

4、Simple parameter setup interface, big screen chart and character LCD display.
