WATER LEAKAGE DETECTOR FOR COOLING WATER OF PLASMA TORCH

摘要

PROBLEM TO BE SOLVED: To provide a water leakage detector that can directly detect the leakage of the cooling water of a plasma torch with a higher accuracy.

SOLUTION: This water leakage detector for the cooling water of the plasma torch which heats an object with a plasma arc is provided with a detecting means which judges that the leakage of the cooling water occurs when the voltage of the plasma arc exceeds a preset voltage value.
