Plasma Automatic arc-voltage Height controller THC for CNC Plasma Cutting Machine spare part Ontime AVC118

Model:AVC-118

Brand:Ontime

Instroduction

The AVC-118 is a voltage sensing torch height control system

that is designed for the CNC plasma cutting machines.

During cutting process, the cutting current always keep constant, and the cutting arc voltage will be changed with the

height of torch. When the distance between the torch nozzle and work piece increases, the arc voltage increases, on the

opposite, the arc voltage will decrease. AVC118 plasma arc voltage torch height controller will detect the voltage changes,

then control the distance between cutting torch and work piece via the lifting motor in order to keep the arc voltage within a

given range, so that the height of cutting torch is kept within a corresponding range.
