PLASMA TORCH, AND APPARATUS AND METHOD FOR MONITORING OF PLASMA TORCH

摘要

Disclosed are a plasma torch, a monitoring device for a plasma torch, and a method for monitoring a plasma torch. The monitoring device for the plasma torch in accordance with an embodiment of the present invention includes a first temperature measuring unit separately measuring the temperature of a first coolant inlet in which a coolant is injected to cool a rear electrode and a first coolant outlet which the coolant heat-exchanged with the rear electrode is discharged from; a second temperature measuring unit separately measuring the temperature of a second coolant inlet in which the coolant for cooling a front electrode facing the rear electrode and a second coolant outlet which the coolant heat-exchanged with the front electrode is discharged from; and a display unit displaying the temperature measured by the first temperature measuring unit and the second temperature measuring unit.
