The Miller Trailblazer 325 EFI with GFCI, ArcReach and Wireless Interface Control features full remote front panel access; including remote amp/voltage control and engine start/stop. The wireless interface control is a handheld unit that controls all weld parameters, stores custom weld settings, displays real time engine status and service intervals, and acts as a remote engine start/stop. Wireless interface control saves fuel, reduces jobsite noise, and enhances worker safety and productivity by reducing trips back and forth to the welder. In addition, the 907798003 features 20 volt duplex receptacles with Ground Fault Circuit Interruption protection for operation in areas where state or federal law requires GFCI.


The MillerTrailblazer 325 EFI also comes standard with ArcReach®, which allows the Trailblazer to communicate directly with the remote Miller® ArcReach® wire feeder or Stick/TIG remote without the use of a remote control cable. The secret to this technology is built-in circuitry in both the Trailblazer 325 ArcReach welder and ArcReach wire feeder/remote control that passes remote control signals through the welding leads, eliminating the need for costly remote control cables. ArcReach remote control distance is limited only by the length of your welding cable leads. ArcReach allows your MIG or Flux-Cored welding operation to take place further away from the welding power source and reduces downtime and costs by giving the operator full remote voltage and amperage control capabilities at the site of the weld without using expensive remote control cables. The Trailblazer 325 ArcReach MUST be paired with a Miller ArcReach feeder or ArcReach Stick/TIG remote to get the full benefits of this feature.


The Miller Trailblazer 325 EFI features electronic fuel injection, which saves fuel, offers more reliable starting in all operating conditions and lowers emissions. It is a 325 amp, 100% duty cycle DC welder and 12,000 watt AC generator. The Trailblazer 325 EFI features a Kohler 23 horse power, fuel injected engine with Miller’s exclusive Auto-Speed™ technology. Auto-Speed® matches the engine speed with the welding load. This means that the engine can run at optimum RPM rather than full RPM while under load. This translates into reduced fuel consumption, quieter operation and longer engine life.


The Trailblazer® 325 EFI has the most smooth, stable welding arc in the business. It produces X-Ray quality welds whether you are using MIG, Stick or DC TIG welding processes.

Wireless Interface Control

Get full control of your machine in the palm of your hand, from wherever you are on the jobsite, so you can work hassle free. With wireless interface control, you can:

  • Change welding processes
  • Adjust parameters
  • Select and save preset programs
  • Turn the machine on/off
  • View service reminders
  • And more!

Extend time between fill ups and maintenance intervals while eliminating the need to go back to your machine to make adjustments.

Excel™ power

  • Power at idle — a Miller exclusive. Unlike competitive machines that provide auxiliary power only at 3,600 rpm (max), Excel power delivers a full 2,400 watts (20 A) of 120-volt inverter-based, pure sine wave power at all speeds, including idle. With Excel power you can operate jobsite tools like grinders at quiet, fuel saving speeds. Refueling time and operating costs are reduced with Excel power, which means more productivity and profitability. Plus everyone on the jobsite gets a better working environment because noise levels and exhaust emissions are lowered. Excel power — available only from Miller.

Electronic fuel injection (EFI)

  • Improve fuel efficiency for maximum productivity and profitability. Adding EFI to your Trailblazer welder/generator adds multiple benefits. With EFI, you’ll get faster, more-reliable starts in any weather — no choke adjustments needed. EFI-equipped Trailblazer machines are also up to 42 percent more fuel efficient than standard carbureted models, improving profitability. Plus, refueling less frequentl

Auto-Speed™ Technology

  • Matches engine speed to load — a Miller exclusive. Get the welding power you need — plus reduced fuel consumption and lower noise levels for a more-profitable, safer jobsite.Unlike competitive machines that operate at 3,600 rpm (max) under any load, Miller-exclusive Auto-Speed technology responds to weld requirements by automatically adjusting engine speed to one of four rpm levels so the engine never works harder than necessary.Refueling time and operating costs are reduced, which means more productivity and profitability. Plus everyone on the jobsite gets a better working environment because noise levels and exhaust emissions are lowered.

Dynamic DIG™

Unlike conventional DIG that provides a preset amount of short-clearing current, Miller’s proprietary Dynamic DIG works on a time-based algorithm that automatically adjusts the amount of current required to clear a short. What does this mean? A smoother more consistent arc that can be tailored to match application, material, fit-up, and welder technique.

ArcReach® Technology

  • ArcReach technology uses existing weld cables to communicate process adjustment commands back to the welder generator. With an ArcReach system, amperage & voltage are conveniently located at the operator’s fingertips – not back at the power source.

Unbeatable arc performance

  • Wide amperage output with better welding deposition rates 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.

Cleaner and Stronger Generator Power

  • Combined with a 25-horsepower engine, Trailblazer welder/generators offer up to 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.

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 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 jobsite needs a welder/generator, it needs a Trailblazer welder/generator — because no other gas-fueled choice is as quiet.

More portable, uses less truck and jobsite space

  • Trailblazer welder/generators are up to 17 percent smaller and 10 percent 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.
