Multi-operator generators are intended to power four or two welding torches of direct current arc welding (MMA). They are suitable for operation at temperate climate conditions within the range of ambient temperature from minus 40°C to plus 40°C the relative humidity 98% for temperature of plus 25°C.
Generators SG-2x250/5,5 and SGE-4x250/5,5 consist of welding generator and built-in auxiliaty asynchronous generator with power of 5,5 kVA, 230 V. Welding generator proper is brushless induction generator having original current control set-up ensuring perfect welding process and excellent formation of welding suture. Additional asynchronous generator, also having no brushes and rotating contacts, ensures ideal wave pattern and is suitable to power the most pretentious users of electrical power.
Generators SGE-2x350/8 are synchronous generators with outputs of alternative and direct current connected with two converters Multi-Weld 350 from company Lincoln (USA) or two converters KCY-320 from company Selma (Ukraine) or corresponding other converters. Alongside manual arc welding (MMA) the generator also provides with automatic welding (MIG-MAG), has control at the place of welding and functions „Hot start" and „ARC Force".
