Arc Voltage Torch Height Controller
1.Application range: the cutting torch height control of plasma cutters having (or within a certain voltage range having) constant current characteristic, most of which are of imported or domestic model.
2.All interfaces are of isolating circuits, improving the anti-interference capability of torch height controller.
3.It is provided with anti-bumping function of cutting torch, wherein, whenever the cutting torch contacts the steel plate, the check circuit will activates to lift the cutting torch to the initial location height.
4.It has over-arc voltage protection function, wherein, when the actual arc voltage is lower than the set arc voltage 30V (adjustable), the over-arc voltage will be cancelled automatically to prevent the cutting torch from touching the steel plate during over wire leading-out and over burning and cutting.
5.It can display the set arc voltage and actual arc voltage on the panel LED for the convenience of real-time monitoring on equipment by operators.
6.It is capable of performing protection cap protected underwater cutting (to be stated when ordering).
7.It is capable of performing cutting torch control, arc ignition test, and controlling over initial location height and punching time through the panel, which is convenient and faster.
