Miller Trailblazer 330 EFI Welder Generator, Excel Power, WIC, Polarity Reverse

The Miller Trailblazer 330 EFI welder generator with Excel Power, WIC and polarity reversing is a Kohler EFI gasoline engine-driven welder rated 330 A for stick/TIG and 325 A for MIG/flux-cored at a 100% duty cycle. Wireless Interface Control lets the operator run the machine from anywhere on the jobsite, and auxiliary power is 10,500 W continuous.

Through WIC the operator can switch welding processes, tweak parameters, store and recall preset programs, turn the machine on or off and check service reminders without walking back to the unit, which Miller links to longer gaps between refueling and service. Polarity reversing and Excel Power are also included. ArcReach sends process adjustments over the existing weld cables, Dynamic DIG adapts short-clearing current to the stick application, QuietPulse lowers audible noise in DC pulse welding, and GFCI protection is fitted.

Rated output is 330 A at 30 V for CC/DC stick/TIG and 325 A at 30.25 V for CV/DC MIG/FCAW, over a 20-330 A range, and single-phase auxiliary power is 10,500 W continuous and 12,000 W peak, with weld and auxiliary circuits kept separate. The 23 hp Kohler EFI engine idles at 2400 RPM, Auto-Speed varies it from 2,400 to 3,600 rpm to match weld output, and the tank holds 11 gallons. Weldable metals are aluminum, stainless steel and steel, with a standard lift eye and optional running gear/cart and trailer.
