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.
