Introduction:

                SD series are of high performance, self-exciting double-use generators specially designed for generating welding separately, or for welding and moderately lighting simultaneously. This generator is suited for direct coupling or belt driving with a medium speed petrol or diesel, or AC or DC motor.

                      The output voltage of generator is 230V AC, and that of the welding is no greater than 80 volts, its frequency is either of 50Hz or 60Hz. Other rated voltage can also be designed according to the. When the double-use set is used for generator with a 5% speed regulation of the prime mover, underload variation from 

0→100% and 100%→0 cosΦ1.0, the steady-state voltage regulation rate is not greater than ±5%. As load being suddenly changed, the double-use generator can be rapidly adopted and operated steadily. When it is used foe welding, it has a good characteristic performance for welding current to produce a steadily electric arc thus ensured the quality of welding.

                 SD series generator  is of drip-proof, axial ventilation type. The construction of its frame with front and rear end cover is of casting iron. On the end cover of the drive end, there installed a set of tapes spigot holes, which can be fitted wih a prime mover conveniently. At the same time, there are two screen mesh plate on the outlets of the drive and the inlets of the no drive and to provide ample protection to the machine, After removing this screen mash plate at the non drive end, the brushers and slip rings are easy to access.

Description:

• SD series generating and welding dual use sets will be the best to be driven by an internal combustion engine.
• They can be used as mobile or stable power supply unit which is suitable for using in towns, countryside's, boats, workshop for lighting or welding purpose. 
• This series alternator can serve as lighting or as welding individually, furthermore, they can serve both as welding and as illumination simultaneously.
