Miller Electric's Bobcat and Trailblazer welder/generators now feature engines with more horsepower. Increased horsepower provides more welding output for larger diameter wires, faster travel speed and more generator power under heavier loads. The new engine options are a 23-hp Kohler and 22-hp Robin gas engine. Another enhancement to the Trailblazer, Auto-Crater helps eliminate crater-related DC TIG weld defects. Engine manufacturers warrant the engines separately. All other components are covered by Miller's True Blue three-year factory warranty.
