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.

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
