MQ Power Corp. has launched a new welder/generator for use by welding supply houses and the rental markets. Operating as a 225 amp welder and a 6 kW 120/240 volt a.c. generator, the Scorcher 225, manufactured for MQ, Carson, Calif., by Denyo Ltd., is the first model to include constant voltage operation and expands the company's line of welders joining 300 and 400 amp models.

Power for the new welder/generator is a water-cooled, two-cylinder Kubota Z482 diesel rated 12.5 hp at 3600 rpm. The engine comes equipped with an automatic idle control, hour-meter, warning light, fuel gauge, pre-heat lamp and self-priming fuel system. A gasoline version of the Scorcher 225 is due later this month.

One of the primary features of the new set is its lower noise level; 68.7 db(A), according to MQ. The set also features 100 percent duty cycle at 200 amps and a brushless generator design for lower maintenance costs. The automatic idler helps reduce fuel consumption, while the self-priming fuel system aids in restarting the unit.

The package is able to operate simultaneously as a welder and generator and has controls for both CV and CC welding. MQ said the set features outstanding arc characteristics, ideal for welding pipe and structural steel. The system is available with an optional over-the-road trailer.
