The resistance rate of the deionized water is required to be higher than 0.5MΩ—cm. After
some time of use, the deionized water’s resistance rate will be lowered down and it may
have impurities, dirt or turbidity that will make the xenon lamp not lightened or pollute the
laser cavity and glass tube, and lower the luminous efficiency. If so, the used deionized
water should be substituted immediately (if the machine is continuously operated, the
deionized water in the system should be replaced once a week).
The heat exchanger works through the Freon to exchange the heat for the cooling water and
carry away the heat in the purified water. A flow controller and over-temperature contactor
are installed in the cooling system to monitor the water that comes into the laser. Once the
flow of the circulating water is insufficient or the water pump in the system works abnormally,
the power for the laser should be turned off immediately so as to avoid the accident that can
be caused by the explosion of the lamp bar.

The parameters aboved are based on 200W channel letter laser welder. Should for 300W and 400W
machine, the current and pulse width should be decreased, the min. current is 50A. Should the laser is
strong, then reduce pulse width, or enlarge the facular.
Whatever the material is, the best welding is the proper facular when focus length is correct. There will be
