Trailblazer®325 Gas Welder/Generators 

Trailblazer® 325 Gas technologies

You need to minimize worksite fuel consumption and noise — and maximize productivity. Which is why you need a Trailblazer welder/generator. No other gas-fueled 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.

Total control where you work

With optional Wireless Interface Control, you get full control of your Trailblazer welder/generator in the palm of your hand. Change welding processes, adjust parameters, select and save preset programs, turn the machine on/off, get service reminders and more from wherever you are on the jobsite. Extend time between fill-ups and maintenance intervals while eliminating the need to go back to your machine to make adjustments.

Unbeatable welding performance

Miller's proprietary Dynamic DIG™ technology automatically adjusts the amount of current required to clear a short, delivering a smoother, more consistent arc that can be tailored to match the application, material, fit-up and welder technique.

Maximum cost savings

Only Miller®Trailblazer machines have fuel-saving Auto-Speed technology. Add optional Excel power and EFI to save even more on fuel costs, and enjoy a combination of advanced, profit-enhancing features.

Safer, more productive jobsites


Every year, your outdated welding equipment can pose safety risks while wasting hundreds of productive work hours — and thousands of dollars in profit — by forcing welders to make numerous walks to and from their welding power sources. Step up to Trailblazer machines with ArcReach® technology, which allows welders to make parameter adjustments right at the weld joint. The result: safer jobsites, more arc-on time and improvements to your bottom line. You'll also get quieter jobsites with a Trailblazer, improving safety and productivity because work crews can communicate easier.

More portable, smaller and lighter

The gas Trailblazer 325 is up to 17 percent smaller and 10 percent lighter than competitive machines — which means moving it is faster and easier, for maximum productivity. Because it takes up less space, trucks can carry more equipment and gear — so your crews can be ready for anything.

Cleaner and stronger generator power

Combined with a 25-horsepower engine, a Miller Trailblazer 325 offers 10,500 watts of clean, truly usable generator power. 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.
