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 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. 

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.

Cleaner & Stronger Generator 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.

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

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.

Auxiliary Power*

  • 2 x 15 Amp Sockets
  • 1 x 32A
  • RCD Protected

3 Year Warranty 

Welder/generator is warranted by Miller for 3 years, parts and labour.

For details refer to Miller’s True Blue warranty statement. Engine is warranted separately by engine manufacturer.

*Generator auxiliary power is 60Hz, and intended for operating equipment associated with welding, such as angle grinders, drills and floodlights. Some Australian 50Hz equipment incorporating induction motors, such as pumps, fans, air compressors, refrigeration or air-conditioners, may not operate correctly and could be damaged. Refer to appliance supplier or manufacturer to confirm suitability
