Unbeatable Arc Performance
Miller® Trailblazer welder/generators deliver a wider amperage output with better welding deposition rates, which means you can get jobs done faster, saving time and money. The Trailblazer also has precise arc control, which allows you to fine-tune the arc to match your personal preferences and quickly dial in the perfect parameters to optimize weld quality and maximize productivity across a variety of applications and welding processes.
Auto-Speed™ Technology - Matches engine speed to load, reducing fuel use and noise.
Matches engine speed to load — a Miller exclusive Get the welding power you need — plus reduced fuel consumption and lower noise levels for a more-profitable, safer jobsite. Unlike competitive machines that operate at 3,600 rpm (max) under any load, Miller-exclusive Auto-Speed technology responds to weld requirements by automatically adjusting engine speed to one of four rpm levels so the engine never works harder than necessary. Refueling time and operating costs are reduced, which means more productivity and profitability. Plus everyone on the jobsite gets a better working environment because noise levels and exhaust emissions are lowered. Auto-Speed technology: available only from Miller.
Excel™ Power (Option)
Power at idle — a Miller exclusive Unlike competitive machines that provide auxiliary power only at 3,600 rpm (max), Excel Power delivers a full 2,400 watts (20 A) of 120 V inverter-based, pure sine wave power at idle. With Excel power you can operate jobsite tools like grinders at quiet, fuel-saving engine speeds. Refueling time and operating costs are reduced with Excel power, which means more productivity and profitability. Plus everyone on the jobsite gets a better working environment because noise levels and exhaust emissions are lowered. Excel power: available only from Miller.
Cleaner and Stronger Generator Power
Combined with a 24.8 horsepower engine, Miller Trailblazer welder/generators offer 12,000 watts of clean, truly usable generator power that is Accu-Rated™, not inflated: tested to deliver uninterrupted peak output for a minimum of 30 seconds for big loads, so you can get more jobs done. An independent welder and generator power system ensures no interaction between jobsite tools and the welding arc, while advanced generator technology virtually eliminates power spikes and other electrical imperfections — so welds are cleaner and jobsite tools can run without interruption, maximizing quality, productivity and profit
More portable, uses less truck space
Miller Trailblazer welder/generators are up to 24% smaller and 11% lighter then competitive machines — which means moving them is faster and easier, for maximum productivity. And because they take up less space, Trailblazer welder/generators let work trucks carry more equipment and gear — so your work crews can be ready for anything.
Safer, more productive jobsites
Quieter jobsites are safer and more productive because work crews can communicate easier, and work can start earlier and end later — even in noise-sensitive areas. If your worksite needs a welder/generator, it needs a Miller Trailblazer welder/generator.
Maximum cost savings
Less money spent on fuel means more profit for you. Every Miller Trailblazer welder/generator has fuel-saving Auto-Speed technology; add optional Excel power to save even more on fuel costs and enjoy a combination of advanced, profit-enhancing features that are only available on a Trailblazer welder/generator.
