325 Diesel Welder/Generator 

Trailblazer® 325 Diesel technologies

You need to minimize worksite fuel consumption and noise — and maximize productivity. Which is why you need a Trailblazer 325 Diesel 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.

This diesel welder/generator:

  • Uses the same fuel as your other diesel-powered heavy equipment
  • Complies with jobsite restrictions that prohibit the use of gasoline-fueled equipment
  • Is designed for optimal engine life
  • Delivers exceptional fuel economy

Work more. Save more.

Unbeatable arc 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

Less money spent means more profit for you. Only Miller® Trailblazer machines have 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. With legendary Miller reliability and the inherent longevity of diesel engines, the Trailblazer 325 Diesel is designed to save you money year after year.

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Every year, your outdated welding equipment can pose safety risks while wasting hundreds of productive work hours — and thousands of dollars in profit — by forcing welders to make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 machine, improving safety and productivity because work crews can communicate easier.

More portable, smaller and lighter

The Trailblazer 325 Diesel is up to 24 percent smaller and 10 percent lighter than competitive machines — which means moving it is faster and easier, for more productivity. Because it takes up less space, trucks can carry more equipment and gear, and your crews can be ready for anything.

Cleaner and stronger generator power

Combined with a 25-horsepower engine, the Trailblazer 325 Diesel 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.

Welding Technology Saves Time on the Jobsite

Miller® ArcReach® technology helps save significant time for M&M Welding, since welders can adjust parameters at the weld joint.

ArcReach Technology Helps Ensure Optimal Weld Settings

Easily set optional weld settings for any job at the wire feeder or remote with ArcReach® technology.

Fuel Efficient Welding Equipment Keeps Noise Down

M&M Welding relies on Trailblazer 325 welder/generators with Auto-Speed™ technology to get the necessary power with less noise.
