The ESAB Ruffian ES 150G is a robust engine-driven welder designed to meet the rigorous demands of field fabrication, civil construction, and agricultural repair. Combining a high-performance DC Stick welder with a versatile AC generator, the Ruffian ES 150G provides a comprehensive solution for remote worksites where grid power is unavailable. At its core lies a reliable 14 HP Kohler Command PRO CH440 gasoline engine, renowned for its durability and consistent power delivery.
Unlike traditional engine drives, the Ruffian utilizes advanced inverter technology to produce a welding arc of exceptional stability and smoothness. This technology allows for precise control over arc parameters, including adjustable Arc Force, which is critical for preventing electrode sticking and ensuring deep penetration when using difficult electrodes like E6010. The machine delivers a rated output of 150 Amps at 60% duty cycle, making it capable of handling heavy-duty welding tasks without overheating or interruption.
Productivity on the job site is maximized thanks to the Ruffian's independent auxiliary power output. The machine provides 4.5 kW of peak AC power (4.0 kW continuous), allowing operators to run grinders, drills, lights, or even small plasma cutters simultaneously while welding. Because the generator voltage is independent of the welding current, engaging power tools will not cause the welding arc to fluctuate, ensuring consistent weld quality. The unit features four 120V 20A GFCI receptacles and one 240V receptacle, all protected by circuit breakers.
Weighing in at approximately 248 lbs and equipped with large industrial-grade wheels, the Ruffian ES 150G is designed for maneuverability across rough terrain. The ergonomic, removable handles distribute weight evenly, making it easy to position the unit exactly where it is needed. A 5-gallon fuel tank ensures extended runtimes, while the integrated engine hour meter aids in tracking service intervals. With a rugged IP23S enclosure, this machine is built to withstand the elements and provide years of reliable service.
