PLASMA CUTTING DEVICE, AND COOLING METHOD FOR PLASMA TORCH
PROBLEM TO BE SOLVED: To extend the life of a plasma torch by increasing the flow rate of coolant liquid supplied to the nozzle of the plasma torch. SOLUTION: Within the plasma torch (10), an electrode coolant liquid passage (60, 84, 85, 86 and 64) which supplies coolant liquid to an electrode (80),...

description | PROBLEM TO BE SOLVED: To extend the life of a plasma torch by increasing the flow rate of coolant liquid supplied to the nozzle of the plasma torch. SOLUTION: Within the plasma torch (10), an electrode coolant liquid passage (60, 84, 85, 86 and 64) which supplies coolant liquid to an electrode (80), and a nozzle coolant liquid passage (56, 70, 92, 72 and 68) which supplies coolant liquid to the nozzle (88), are provided separately as parallel or independent coolant liquid passages and are mutually electrically insulated from one another. The flow rate of coolant liquid in the nozzle coolant liquid passage is greater than the flow rate of coolant liquid in the electrode coolant liquid passage. COPYRIGHT: (C)2008,JPO&INPIT |
