Fast rise time
AMADA Transistor-controlled welding power supplies have rise times 4.5 times faster than that of conventional* models. high quality welding can be accomplished in a short period of time on small work pieces.
* Compared with 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.

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
Two weld heads can be controlled by one power supply. It contributes to cost and space savings.
