Miller Trailblazer 330 EFI Welder Generator, Kohler, Excel Power, Battery Charge

The Miller Trailblazer 330 EFI welder generator with Excel Power and battery charge 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. Its charger supplies up to 150 A DC for 12 V and 24 V batteries, crank assist reaches 300 A, and auxiliary power is 10,500 W continuous.

Battery charge/crank assist helps keep jobsite equipment with weak batteries running: charging output reaches 150 A DC for 12 V and 24 V batteries, and crank assist delivers up to 300 A. Excel Power is also included, and Auto-Speed tunes engine speed to the weld and battery charge load. 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.
