Product Description

1. Installation Requirement

   Make sure to follow the operation instructions of model W4 as shown in the illustration. The dedicated power DY*3 should be equipped. The positive pole is in high voltage (the ignition voltage is *4kv). It may cause the following consequence when it is failed to follow the instruction: Arcing; the inner tube will be punctured by electricity and may cause water leakage.  

1. Operation conditions

   ● Water cooling: using purified water; 3 to 5 liter/minute; water temperature: *0℃**0℃.● The operating environment: temperature ***0℃, humidity ****0%.● The working current: test current is *9mA. Maximum working current is *0mA. The running current must be kept below *8mA. The life span can reach *0,**0 hours if the current is kept below *6mA. The ammeter indicating current must be connected to the negative electrode of the laser tube.● When it is working under over-high current for long term, the negative pole will appear brown yellow, and the life span will be reduced rapidly.● To protect dust from going into the insulation sheath, please wrap it with plastic film. 
2. Working Performance ● Cutting function.● Engraving function: Very good, when the working current is 4mA and the tube is in the state of preionization, the laser can be used for high-frequency impulse engraving.
