Polar switchable type:MD-B4000B．MD-B2000B
- ◆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.
