  • Ruffian ES 150G is a lightweight, powerful, all-in-one DC Stick welding machine and AC generator combined
  • As a welder, Ruffian uses inverter technology to provide up to 150 A of reliable welding power at 60% duty cycle in a very stable arc that helps avoid rework
  • As an AC generator, Ruffian uses a 14 HP Kohler® engine to deliver up to 4.5Kw starting power
  • 120 VAC and 240 VAC outlets provide versatility to run lights, grinders, hand tools – even light-duty plasma cutters and MIG/TIG welders – and to use as emergency backup.


  • IP23S


  • Advanced control over arc parameters, including adjustable Arc Force, to optimize the arc - especially with 6010 electrodes
  • Impressive power output of 150A at 60% duty cycle
  • Thermal protection for the welder and generator guaranteeing a long, useful life
  • Latest inverter technology ensures a stable and smooth stick arc that produces the cleanest welds
