2.13 INAPPOSITE USE OF LASER OSCILLATOR
Inapposite use and the result are described in each explanation place.
Inapposite major use are described in the following.
(1) The gas with different composition and purity from the
specification is connected with the oscillator. The oscillator does
not work normally and do the protection movement. In the worse
case, the oscillator breaks down.
(2) The gas piping with different material and structure from the
specification is used. A leakage of the laser gas and a defective
composition are occurred. In the worst case, the oscillator breaks
down.
(3) The water piping of the material, which corrodes to water, is used.
Water is blocked by the generation of rust. If cooling water does
not flow in a regulated amount, the oscillator will not work
normally.
(4) Cooling water is not regularly exchanged . Water is blocked by
the generation of rust. Moreover, it is easy for the water fittings
in the oscillator to corrode. In the worst case, the fittings are
damaged and the water leak happens.
(5) The oil of turbo blower and the exhaust pump is not regularly
exchanged. Turbo blower is damaged and the oscillator does not
work. The exhaust pump is damaged similarly.
(6) The filter of the exhaust pump is not regularly exchanged. The
exhaust ability of the exhaust pump decreases. Moreover, white
smoke comes out from the pump exit and the oil leak happens. In
the worst case, the oscillator does not work.
(7) You will touch an unrelated place when usually maintaining. In
the oscillator there are adjustment place. The adjustment place is
the best value when shipping. When the adjustment shifts, the
oscillator will not work normally. It is necessary to adjust it by
service man that was trained.
(8) You open the panel immediately after the oscillator was stopped
and oil is exchanged.
(9) There is a place of the high temperature immediately after the
oscillator stopped. When you touches there, you will do the burn.
After getting cold of the oscillator, open the panel. Refer to safety
in Chapter 2 for the place of the high temperature.
