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.
Aspect 375 is a TIG welding power source for the advanced professional fabrication market in critical welding applications subject to the most rigorous testing requirements, including X-ray analysis.
The Dimension 650 provides both power-intensive output for heavy welding and carbon-arc gouging, as well as precision arc characteristics designed for thin-metal welding, the company says.
The SubArc Digital Series of power sources, interface controls and accessories include digital control and communication electronics designed to improve weld performance and simplify the integration of the equipment in more advanced applications, the company says.
Big Blue 400 Pro diesel-engine welder/generator now has a 400-amp output available in a 300-amp package.
