AMADA Micro Welding Section
Fine Spot Welders
Transistor-Controlled Welding Power Supplies
Multiple connection: MD-A10000A, MD-B5000A
Short-time, large-current welding by multiple connection of power supplies.
Features
- ■ Multiple connection of power supplies realizes high power welding at short time!
-
- MD-A10000A ：Maximum twelve units connectable (One master and eleven slave units)
Design your own system to add power supplies as much as you need to obtain enough power.
-
* At left: Customised weld head (Maximum weld force: 20kN)
- ■ One master unit to control all connected units
-
It does not necessary to set the weld schedule at each unit anymore. It needs to set only at a master unit which controls all slave units.
-
- ■ All units' current feedback
-
The current feedback feature controls to stabilize current of all connected units collectively.
- ■ Three control types to choose from
-
- ■ Plarity switchable type: MD-B5000A
-
MD-B5000A：Connection of a master and a slave unit.
Three control types; which are same as MD-A10000A, can be selected.
Peltier effect can be reduced and shape of nugget can be uniformed. -
