3.5 Working Conditions
Water cooling:
The cooling liquid is pure water with standard water temperature from 10℃ to 50℃. And
the flow rate is 2-5 liters per minute.
Application environment: temperature from 2℃ to 40℃, humidity from 10% to 60%.
Current:
The detection current is 28mA. The max operating current must be controlled at 28mA or less.
And the long-term operating current must be controlled at 26 mA or below. Working life can reach 8,000
hours if the current is 24 mA or less. All current above must be based on the actual current of the ammeter
connected in series on the cathode line. The undesired consequences by illegal operation may as below.
Tips:
The negative electrode will turn yellowish if long-term overcurrent. What’s more, it will shorten
the life.
Please keep the plastic wrap around the high-pressure jacket to prevent dust from entering the vicinity of
the electrode.
3.6 Working Functions
Working functions include cutting and engraving. Taking engraving as an example, 4mA is recommended
to produce pulse with high frequency under preionization state for better engraving.
3.7 Notices
The surface of beam output lens cannot be scrubbed with any tools such as cotton balls, otherwise the
power will be serious affected. Here are several methods for cleaning.
(1) When the lens is contaminated, do not use the laser tube;
(2) Blow the lens surface obliquely with balloon;
(3) If the above no effect, user needs to remove the lens and use a cotton ball with a little alcohol to rotate
the lens.
(4) No need too much alcohol, but the glue layer of the adhesive lens cannot be touched in case of gas
inside escaping.
(5) The laser cannot be used till alcohol evaporating.
(6) Do not scrub the lens with acetone. The best way to protect the lens is keeping the environment clean.
(7) When testing the beam on plexiglass, please keep it 300mm from the mirror.
3.8 Safety
Goggles are necessary when debugging because the laser belongs to invisible beam. Positive electrode
carries high voltage. By the way, users must pay attention to the safety signs.
