Blue Star 145 and 185 Series engine-driven welding generators have a five-gallon fuel capacity and auto idle to reduce fuel consumption and noise levels. Useable peak power is 4,500 watts for the 145 and 6,000 watts for the 185. With the optional running gear, the units are one-man portable. The welder-generators occupy little space when truck mounted. The Series is covered by the True-Blue three-year factory warranty.
