Tube Diameter: 50mm; Beam diameter: around 3mm. Working Voltage: 17KV (Trigging Voltage=23KV). First, connect the positive and negative pole on the laser tube to the positive and negative terminals on the machine, and cover with insulating tape. Connect the cooling water pipe, the connection method is to feed water from the positive pole, the negative pole is out of water and keep the water inlet of laser tube under the laser tube and the interface cannot be leaked. Before use, the water reservoir must be filled with water.
After passing through the water, must be no air bubbles in the water-cooled tube. And you might have to readjust the mirrors to the laser head to make your machine work right.
