Trailblazer® welder/generators 

You need to minimize worksite fuel consumption and noise — and maximize productivity. Which is why you need a Trailblazer welder/generator. No other compact machine in the 300-amp class delivers more welding power or more auxiliary power with better fuel efficiency and less noise — for productive, profitable, quieter jobsites.

Work more. Save more.

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.

Fewer refueling trips

No other gas welder/generator in the 300-amp class lets your crews spend more time working and less time refueling — because only Miller Trailblazer welder/generators provide Auto-Speed technology, plus Excel power and Electronic Fuel Injection (EFI) options, to deliver maximum runtime.

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 and Electronic Fuel Injection (EFI) 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.


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 — because no other gas-fueled choice is as quiet.

More portable, uses less truck space


Miller Trailblazer welder/generators are up to 17% smaller and 10% 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.

Cleaner and stronger generator power

Combined with a 25-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.

Video 2 of 2: Trailblazer Sound Reduction Increases Safety, Productivity for InterCon Construction

A quieter jobsite is a safer, more efficient and more comfortable place to work. Miller engineers built the Trailblazer® to run up to 68 percent more quietly than previous models which means your crew can communicate more easily, start jobs earlier, end later, and complete more work around hospitals, businesses and residential areas. Watch this video to see how the sound reduction has improved communication and created a safer, more productive work environment for InterCon Construction.

Structural Steel Welding and the new Trailblazer 325 EFI with Excel Power

Coastal Steel, based in Tacoma, Wash., works with the new Trailblazer 325 EFI with Excel power from Miller. The new welder/generator is helpful for companies like Coastal Steel by allowing welders to work longer without refueling, lowering fuel use and related costs, and by lowering sound output by as much as 68 percent for better communication and work in residential/commercial areas. Independent welder and generator power further ensures welding quality as there is no interaction between the welding arc and power tools.

Video 1 of 2: InterCon Construction Increases Fuel Efficiency, Productivity with Trailblazer 325 EFI

Like many contractors in the utility and construction industries, InterCon looks for ways to be more efficient. With so many projects and employees, saving money through reduced fuel costs or increased worker productivity time on jobsites, for example, can have a big financial impact. To gain more fuel efficiency and to get more power and flexibility for welding materials of different thicknesses, InterCon transitioned to Miller Trailblazer 325 welder/generators with Excel™ power and EFI for their field trucks. The switch has paid off in decreased fuel costs of up to 20 percent and as much as four or five hours of added productivity time each month for InterCon's welding operators. The improved fuel efficiency of Trailblazer 325 welder/generators means fewer stops for gas fill-ups, keeping InterCon operators working longer at their welders, grinders and cutting tools.
