แหล่งจ่ายเครื่องเชื่อมเลเซอร์ Amada miyachi transistor power supply md-a8000b md-a4000b md-a1000b

Standard: MD-A8000B MD-A4000B MD-A1000B 
Polarity switchable: MD-B4000B MD-B2000B
Two channels: MD-C2000B

Clean fine finish in a short time of welding.

Features

• Fast current rises.

  Since the welding current rises 4.5 times faster than that with the *conventional welders, high quality welding can be accomplished in a short period of time on small work pieces.
  * Compared with the conventional model MD-1500E

• No welding transformer needed

  The welding current is directly controlled with fast switching by transistor, so no welding transformer is required.

• Three control types to choose from

  You can choose from three types of control - "constant current," "constant voltage," or "constant voltage and current" - to suit the workpieces.

• Built-in pre-check function

  Applying current on the workpiece before the main current, it is possible to judge whether or not there is a workpiece set on the electrodes, and to evaluate the status of workpiece.

• Polarity switchable type

  This can eliminate the Peltier effect (polarity effect) and provide uniform nugget diameters on series welding.

• Two-channel type

  With this type, it can reduce the cast and save some spaces for time difference welding.
