Welder Protection System

In the event of an overload, this welder/generator is equipped with an welder protection system . If an overload is detected while operating the welder/generator, the welder protection system will shut down the engine.

Oil Pressure Warning Alarm

In the event of low oil pressure (engine), this welder/generator is equipped with an engine protection fail safe system . If low oil pressure is detected while operating the welder/ generator, the engine protection system will shut down the engine.

If this condition (low oil pressure) should occur, please refer to the engine troubleshooting table in this manual.

Excitation System

The SGW-250SS welder/generator uses a brushless exciter to create rated output electricity. This system will use the mechanical energy generated by the 3600 RPM engine to spin the rotor (or armature) inside the generator (or alternator end).

The motion created by the rotor (which holds copper coils) spins inside a housing of permanent magnets called the "STATOR". A magnetic field is created by the stator and produces an electrical current.

Engine

The SGW-250SS is powered by an air-cooled, 4-cycle HONDA gasoline engine. This engine is designed to meet every performance requirement for generator. Reference Table 1, page 9 for engine specifications.

In keeping with MQ Power's policy of constantly improving its products, the specifications quoted herein are subject to change without prior notice.

Figures 2 and 3 (pages 14-15) show the basic controls and indicators for the SGW-250SS welder/generator.
