The MV-7A's infinitely variable power control ensures uniform power regardless of tissue variations. The MV-7A has a fully rectified current for optimum simultaneous cutting and coagulation - or either procedure separately. It has new, efficient, cool running circuits and components along with short-circuit-proof output - eliminates transistor failures. This machine is shock and vibration proof with a rugged, simple mechanical design. Each MV-7A unit is factory tested and quality controlled. Features COAG & CUT/COAG modes.
