    I am working with an old Argon ion laser, so Coherent company is not support this product an more.

    The problem with this laser is that the Cathode current is decreased to 27 A then the laser is turning off by itself with " Fired starter 5x" fault massage. The technical support thinks that the laser tube is old and need to replace by a new one.
    I have checked the water level, interlock, and tube pressure, and every thing is ok. Also, I think there is no problem with the resistance of the four fuses in the power supply.

    Is there any way to fix this laser without changing the laser tube?
