Engine Driven Welders - Miller Trailblazer 325 - MillerWelds | MillerWelds

Trailblazer® Engine-Driven Welder

More work. Less fuel and noise.

Fuel-thirsty, noisy engine-driven welders cut into your profits and make jobsites harder places to work. Reduce operating expenses and improve working conditions with a Trailblazer solution. Whether you need gas or diesel, you’ll get industry-leading fuel economy and reduced noise — plus legendary Miller reliability.

Total control where you work

With optional Wireless Interface Control, you get full control of your Trailblazer engine-driven welder 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

Precise arc control allows fine-tuning and lets users quickly dial in parameters to optimize weld quality and maximize productivity.

Lower expenses, less refueling time

Every Trailblazer model includes fuel-saving technology to save you money and keep crews working. Exclusive fuel-saving advantages include Auto-Speed™ technology and Excel™ power. 

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Every year, your outdated welding equipment can pose safety risks while wasting hundreds of productive work hours — and thousands of dollars in profit — by forcing welders to make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

Trailblazer machines are smaller and lighter than competing models, so they can be moved easier and faster. Because they take up less space, trucks can carry more equipment and gear, and your crews can be ready for anything.

Cleaner, stronger auxiliary power

Trailblazer machines deliver 10,500 watts of clean, truly usable auxiliary power. An independent welder and auxiliary power system ensures no interaction between jobsite tools and the welding arc, while advanced 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.


*ArcReach technology standard on Trailblazer 325 models only. Excludes Battery Charge models. Optional on LP model.
