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

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