By using electronic fuel injection instead of a carburetor, two updated welder generator models cut hydrocarbon and nitrogen oxide emissions by double digits.
By replacing the carburetor with electronic fuel injection (EFI), Miller Electric Mfg. Co. has managed to cut hydrocarbon and nitrogen oxide emissions by 33 and 27 percent respectively on each of two updated welder generator models, the manufacturer says. The Trailblazer 302 EFI and Bobcat 250 EFI are the only EFI engine-driven, twin-cylinder welder generators available in the industry, says Miller, improving claimed fuel economy up to 27 percent. Weld output and generator power is increased to 12,000 peak and 10,500 continuous watts on both multi-process machines, which offer stick, MIG, flux cored, AC/DC TIG and gouging capabilities.
