Miller Trailblazer 325 Features

Auto-Speed™ Technology

The Trailblazer 325 welder generator is equipped with Miller-exclusive Auto-Speed technology. It intelligently matches engine speed to load for efficient operation. Unlike competitive machines, it enhances productivity by automatically adjusting engine speed across four rpm levels based on weld requirements. This results in reduced fuel consumption, lower noise levels, and fewer exhaust emissions.

With Trailblazer, expect profitable, quieter job sites, less refuelling time, and lower operating costs.

Experience Peerless Arc Performance

With the Trailblazer 325, you’ll enjoy a wide amperage output and superior welding deposition rates. This means faster completion of jobs, leading to significant time and cost savings.

The precise arc control lets you customise the arc to your preferences, ensuring optimal weld quality and maximising productivity across various applications and welding processes. With the Trailblazer 325, a more productive, profitable, quieter job site is within your reach.

Excel™ Power (option)

Unlike competitive machines, the Trailblazer 325’s optional Excel™ Power, a Miller exclusive, delivers full power at all speeds, even idle. This generator power system ensures a robust 2,400 watts (20 A) of 120-volt inverter-based, pure sine wave power.

Operate jobsite tools like grinders at quieter, fuel-efficient speeds. The result? Reduced refuelling time and operating costs, increased productivity, profitability, and an improved jobsite environment with lower noise levels and exhaust emissions.

Electronic Fuel Injection (EFI) (option)

Boost your productivity with the Trailblazer 325’s optional Electronic Fuel Injection (EFI). This feature guarantees faster, more reliable starts in any weather, eliminating the need for choke adjustments.

EFI-equipped Trailblazer units provide up to 42% fuel efficiency compared to standard models, resulting in significantly reduced fuel consumption. This means less time spent refuelling and more time dedicated to welding, enhancing your productivity and profitability.

Cleaner and Stronger Auxiliary Power

Powered by a 25-horsepower engine, this Trailblazer welder generator provides up to 12,000 watts of clean, Accu-Rated™, truly usable auxiliary power. It’s tested to deliver uninterrupted peak output for a minimum of 30 seconds for heavy loads.

With an independent welder and auxiliary power system, this technology ensures no interaction between jobsite tools and the welding arc. Its advanced auxiliary power system effectively eliminates power fluctuations and imperfections, resulting in cleaner welds and uninterrupted tool operation, enhancing quality, productivity, and profitability.

Experience Ultra Adaptive Arc Control with ArcReach® Technology

Minimise downtime and enhance productivity with the Trailblazer 325’s ArcReach® Technology. Unlike conventional systems, ArcReach welding technology minimises the need for manual adjustments at the power source.

Instead, it uses existing weld cables to relay process adjustment commands directly to the engine-driven welder. This places amperage & voltage control conveniently at your fingertips, streamlining operations and boosting efficiency.

ArcReach Heater Compatibility

Be at the forefront of your field preheat and bakeout applications with ArcReach Heater Compatibility. This feature allows you to control temperatures up to 600 degrees Fahrenheit (315°C) using induction heating, enabling welders to perform preheating quickly and safely.

As part of the innovative ArcReach technology platform, the ArcReach Heater is an exclusive accessory available for select ArcReach welding power sources.

Convenience of Mobility and Space Efficiency

Trailblazer engine-driven welders offer the convenience of being 17% smaller and 10% lighter than their competitors. This allows for faster, easier movement, directly contributing to maximum productivity. Their compact design means less truck and jobsite space is taken up, permitting work trucks to carry additional equipment and gear.

Maximum Cost Savings

Every Miller Trailblazer engine-driven welder is designed for maximum cost savings. With fuel-saving Auto-Speed technology, less money spent on fuel translates into more profit for you. Opt for additional features like Excel power and Electronic Fuel Injection (EFI) to further reduce your fuel costs. These advanced profit-enhancing features are exclusively available on a Trailblazer engine-driven welder, making it an investment that truly pays off.

3-Year Warranty
