How to use it: 1. Line first electrode connected, (+, -) Do not pick the wrong pole. 2. Cooling water pipe connected, the water connection from the anode, cathode and down into the water on the principle meet, and the interface is not leaking. Must store enough water in the water before use, must weather bubble through water in the water-cooled pipe before use (before use each time you have to look). 3. Automatic detection devices are recommended to join in the net but the laser tube water system to prevent the laser tube without water while at work due to overheating fault Troubleshooting: the high voltage ignition and discharge: 1. Check around the high pressure head there and moist dirt away from the metal part of the machine is too close; the other is the laser power high-voltage connector device is falling from the seat, and whether an internal high-voltage connector device disconnection and destruction. If above normal, then so is the quality of the laser tube itself is a problem. the laser tube broken, cracked, water head off: 1. Water temperature is controlled in the range of 25 ℃ -30 ℃, the cooling water can not ice cold regions, especially after laser shutdown, may not allow the cooling water retention in the laser tube. 2. Whether luminous work under the control of the water protection; (test will not be as luminous water off and emit light or not) 3. There are no water pipes will fight the demolition of the phenomenon. 4. Whether there will be bubbles within the laser tube. 5. Water pressure is normal; if the direction of flow low prices. Package Included: 1 x Laser Tube
