    6. PRECAUTIONS TO BE TAKEN WHEN USING THE EQUIPMENT IN WINTER OR AT A COLD REGION If the temperature drops suddenly, cold protection and heat retention for the equipment will be neces- sary. If no heating system is provided inside the plant, it will be necessary to maintain the circulation operation and immediately add antifreeze solution to the equipment without turning OFF the cooling system before stopping the equipment.

  • Page 29: Identification And Handling Of Failures In General

    7. IDENTIFICATION AND HANDLING OF FAILURES IN GENERAL 7-1. High-tension ignition and electric discharge 1) Check the area surrounding the high-pressure head of the laser equipment for dirt and moisture. 2) Check whether the high-pressure head is positioned too close to the metallic part of the equipment. 3) Check inside the high-pressure connecting device for breaking of wire or breakage.

  • Page 30: Cause Of Occurrence Of High-Pressure Discharge And Breakdown Phenomenon

    7-3. Cause of occurrence of high-pressure discharge and breakdown phenomenon 1) If the power supply of the laser equipment and the mains electricity differ in voltage or the power supply which has different specifications (such as in the case of energizing a low-output tube with a high-output power supply) is used, the rated voltage that the laser tube is able to withstand can be exceeded, resulting in breakage of the laser tube.

  • Page 31: Attenuation Of Output

    7-4. Attenuation of output 1) Extremely high water temperature 2) If the water quality is poor, mucous membrane will adhere to the water cooling tube wall after the equipment has been used for an extended period of time to cause a reduction in the cooling effect. 3) If the laser equipment has been operated for a long time under the condition that the maximum op- erating current value of the laser tube is exceeded, the laser tube will be bleached.
