The AMADA MEA-100B is a high-performance AC welding power supply for precision welding of minute parts, featuring easy operation, a desktop design, and CCC/CE certification. Four welding control systems (secondary constant current, power supply voltage fluctuation compensation) support multi-cycle, single-cycle, and half-cycle welding for precise control. Weld current monitoring (toroidal coil MB-35E-00, programmable limits) and automatic max current programming ensure quality. Technically, it handles single-phase multi-voltage (200-480V AC) up to 86 kVA output. Current accuracy is ±2% against ±10% power supply/load fluctuations. This compact unit (172x390x400mm, 6.5kg) is ideal for stable, high-precision welding.
