Jewelry laser welding machine

  1. No consumable part, one time investment
  2. No pollution but Firmer welding
  3. Easy operation, fast welding speed ,save your time to make more profit .
  4. Not many requirements to the operator, only simple training can operate well

What is the advantage of Dowin jewelry laser welding machine?


Adopted imported ceramic condenser cavity, corrosion resistance, high-temperature resistance, long service life.The laser power feedback control system to ensure the stability of laser energy output.


Motic microscope observation operation,clear and more convenient for operation.


The diameter of the laser welding point is adjustable, and the laser welding has high precision and high accuracy.


YAG machine can welding narrow place, deep cavity repair welding, will not hurt the surrounding wall. It will not deform the mold product or sink around the weld pool.Make up for the short comings of traditional argon arc welding, cold welding in the repair of the fine surface of the welding


Special argon gas protection, control system can freely adjust the inlet and outlet time, repair welding site and substrate will not burn oxidation.When welding fine corners, it will not burn edges.
