The MD-A10000A/MD-B5000A welding power supplies enable short-time, large-current welding. The MD-A10000A connects up to twelve units (max 120.0kA), with a master unit providing centralized control and current stabilization. The MD-B5000A features polarity switching for uniform nuggets, ideal for series welding. Both models offer Constant Current, Constant Voltage, or combined control modes for stable, splash-free welding. Operating on single-phase 100-240VAC, they deliver up to 30V with precise timing.
