Features

Unbeatable arc performance
Wide amperage output with better welding deposition rates 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 — 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 five 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.   Learn More
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-volt inverter-based, pure sine wave power at all speeds, including idle. With Excel power you can operate jobsite tools like grinders at quiet, fuel-saving 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.   Learn More
ArcReach® Technology
ArcReach technology uses existing weld cables to communicate process adjustment commands back to the engine-driven welder. With an ArcReach system, amperage & voltage are conveniently located at the operator's fingertips - not back at the power source.   Learn More
Cleaner and Stronger Auxiliary Power
Combined with a 25-horsepower engine, Trailblazer engine-driven welders offer 12,000 watts of clean, truly usable auxiliary 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 auxiliary power system ensures no interaction between jobsite tools and the welding arc, while advanced auxiliary power 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 Mobile, uses less truck and jobsite space
Trailblazer engine-driven welders are up to 24 percent smaller and 10 percent lighter then competitive machines — which means moving them is faster and easier, for maximum productivity. And because they take up less space, Trailblazer engine-driven welders 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 jobsite requires welding and auxiliary power, it needs a Trailblazer engine-driven welder — because no other diesel-fueled choice is as quiet.
Maximum cost savings
Less money spent on fuel means more profit for you. Every Trailblazer engine-driven welder 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 engine-driven welder.
ArcReach Heater Compatibility
Take charge of your field preheat and bakeout applications up to 600 degrees Fahrenheit (315°C). This system uses induction heating to generate heat in workpieces, so welders can do their own preheating quickly and safely. A part of the ArcReach technology platform, the ArcReach Heater is an accessory for select ArcReach welding power sources.   Learn More
