HP103 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. HP103 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.
