Model Number:GD3-S180 Type:Ultrasonic Cleaner Parts Product name:Ultrasonic cleaner drive board Power:180W Type:Digital Control Voltage:110V The use of circuit board and shock transducer (ceramic chip transducer) is explained. Circuit boards must not be energized without load. No cleaning fluid can be energized during cleaning. The two connection pieces of the shock head can be divided into positive and negative ones. Shake head welding power cord must be welded in two silver layer of one side, the other side is the vibration surface, can be pasted in the wash basin (this is the purchase of ceramic transducer components instructions); silver on the ceramic sheet can not withstand high temperature, soldering iron welding power cord temperature can not the brim, the best use of constant temperature soldering iron, soldering iron temperature set Set it to 250 degrees. The larger side of the shaker head (with a screw hole) can be adhered to the bottom of the cleaning container for the shaking surface. If the screw is welded by argon arc welding and glue is added, tighten it to the bottom of the steel plate. There must be no space at the bottom. The positive and negative poles of the output are connected with the positive and negative poles of the seismon respectively, so they can not be mistaken.
