  • Constant Current & Constant Voltage Weld Output
  • Direct Current Weld Output

ArcReach welding technology minimises the non-value added time spent walking to and from the power source - and maximises arc-on time, weld quality and jobsite safety.

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 job-site. 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 five rpm levels so the engine never works harder than necessary. Refuelling time and operating costs are reduced, which means more productivity and profitability. Plus everyone on the job-site gets a better working environment because noise levels and exhaust emissions are lowered.

Fewer Refueling Trips

No other engine driven welder/ generator in the 300 amp class lets your crews spend more time working and less time refuelling — because only Trailblazer welder/generators provide Auto-Speed™ technology to deliver maximum runtime.

Genuine Power

Trailblazer welder/generators offer 10,500 watts of clean, truly usable generator power that is Accu-Rated™, not inflated: tested to deliver uninterrupted peak output of 12,000 watts 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 job-site tools and the welding arc, while advanced generator technology virtually eliminates power spikes and other electrical imperfections - so welds are cleaner and job-site tools can run without interruption, maximizing quality, productivity and profit.

Maximum Cost Savings

Less money spent on fuel means more profit for you. Every Trailblazer welder/generator has fuel-saving Auto-Speed technology. Enjoy a combination of advanced, profit-enhancing features that are only available on a Trailblazer welder/generator.

Dynamic DIG™ Technology

Ultra-adaptive arc control. Unlike conventional DIG that provides a preset amount of short-clearing current,Miller-exclusive Dynamic DIG technology works on a time-based algorithm that automatically adjusts the amount of current required to clear a short. Delivers a smoother more consistent arc that can be tailored to match application, material, fit-up and welder technique.

Unbeatable Arc Performace

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 finetune 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.


Trailblazer welder/generators use up to 24% less cubic space and weigh up to 10 percent less than other welder/generators in their class — 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.

More Productive Jobsites

Quieter jobsites are more productive because work crews can communicate easier, and work can start earlier and end later — even in noise-sensitive areas. Miller-exclusive Auto-Speed technology makes this welder/generator the quietest Trailblazer diesel yet — rated at 70 db at idle (1,800 rpm). If your jobsite needs a welder/generator, it needs a Trailblazer welder/generator — because no other diesel-fueled choice in this category is as quiet. ArcReach® remote control technology eliminates the need to trace or move heavy secondary weld leads bundled with control cords on the jobsite. Complete remote control of welding processes and parameters improves safety by limiting jobsite movement and reducing slip, trip and fall hazards.
