Transistor Power Supply

Standard: MDA-8000B MDA-4000B MDA-1000B Polarity switchable: MDB-4000B MDB-2000B Two channels: MDC-2000B Clean fine finish in a short time of welding.

Fast current rises.

+ conventional welders, high quality welding can be accomplished in a short period of time on small work pieces.

+ 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.
