Torch Height Control
Automatic torch height control is included on all FastCut CNC models.
The automatic torch height control will precisely maintain the correct height over the work area to create the best possible cut. Updating hundreds of times per second, the height control monitors the arc voltage from the plasma cutter and adjusts the cutting height accordingly.
The height control assembly is built with sealed linear guides and a ball screw drive to produce years of accurate cutting.
A FastCut CNC torch height control senses material by touching, not by grounding. This method removes the need for a ground wire connected to the nozzle, eliminating any risk of the arc jumping to the ground wire and destroying the controller or motors. Also, users can determine pierce height and pierce delay which extends the life of torch consumables.
