New options on Miller Electric Mfg. Co.'s (www.millerwelds.com) Bobcat and Trailblazer gas-powered welder/generators include 23-hp Kohler and 22-HP Robin engines. The company says the increased horsepower allows users to weld faster or to increase deposition rates. Other enhancements include the Auto-Crater feature on Trailblazers that eliminates craterrelated, direct current GTAW weld defect; and a low-fuel shutdown on diesel models that shuts down the engine before the fuel runs out to eliminate the need to re-prime the engine.
