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.
