MDA-10000A - Linear DC Weld Controls

Multiple connection of power supplies realizes high power welding at short time. MDA-10000A: 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.

One master unit controls all connected units. It does not necessary to set the weld schedule at each unit anymore. A master unit is an only unit to need to be set and controls all slave units.

All units’ current feedback. The current feedback feature controls to stabilize current collectively from all connected units.

Polarity switchable type: MDB-5000A. Alternate current flow from plus and minus side reduces Peltier effect and shapes nuggets uniformly. Best suited for series welding applications.

Three control types to choose from. Both MDA-10000A and MDB-5000A employ the following three types of control:

  • Constant Current
  • Constant Voltage
  • Constant Current and Constant Voltage

Key Features MDA-10000A - Linear DC Weld Controls

  • Monitor constant current, voltage, or both
  • Connect up to 12 units together
  • Switchable polarity
