Translational torch height controller for a plasma arc torch

摘要

A plasma arc torch is provided that includes a torch body and a torch height controller. The torch height controller includes a movable part mounted to the torch body and a fixed part connected to a robotic arm. The movable part and the torch body are biased toward a workpiece and are translational relative to the fixed part.
