AC controlled welding power supply: MEA-100A

Best for precision resistance welding of small parts.
Model : MEA-100A

  • Clear display with LED.
  • Up to thirty one schedules can be set.
  • Easy setting by seven press keys.
  • Four welding control systems: Multiple cycle welding/ secondary constant current control, multiple cycle welding / voltage compensated control, single cycle welding/ voltage compensated control, and half cycle welding / voltage compensated control.
  • An automatic maximum current configuration.

    The maximum current setting is automatically configured through test run to optimize the performance of the device.

  • The welding current is monitored using the a toroidal coil.

    The upper and lower current limits can be fixed. This will aid the quality control.

  • Support for export.

    CE and CCC supported. There are also 480V version for USA.
