Miller Trailblazer 330 Diesel Welder Generator, Excel Power, Polarity Reversing
The Miller Trailblazer 330 Diesel welder generator with Excel Power and polarity reversing is a Kubota-powered engine-driven welder rated 330 A at a 100% duty cycle for stick, TIG, MIG and flux-cored work. Weld stud polarity can be switched at the interface, and Excel Power adds 2,400 W (20 A) of 120 V pure sine wave power, idle included.
Polarity reversing switches the polarity of the weld studs from the machine interface. Excel Power is an inverter-based 120 V supply rated 2,400 W (20 A), with pure sine wave output at all engine speeds. ArcReach carries adjustments made at the wire feeder or pendant back to the machine over the existing weld cables, with no control cord. Dynamic DIG tailors short-clearing current to the stick application on a time-based algorithm, and QuietPulse reshapes the DC pulse waveform for quieter pulsed TIG. Setup runs through Auto-Set on an LCD with buttons and knob.
Rated output is 330 A at 31 V for CC/DC stick/TIG and 330 A for CV/DC MIG/FCAW at a 100% duty cycle, over a 20-330 A range and a 15-40 V voltage range. Single-phase auxiliary power is 10,500 W continuous and 12,000 W peak. The 24.8 hp T4F Kubota diesel has glow plugs, idles at 1800 RPM and is varied from 1,800 to 3,600 rpm by Auto-Speed, with an 11 gallon tank. Aluminum, stainless steel and steel are weldable, and weld leads are not included.

Good to know
Engine-driven equipment gives off carbon monoxide: run it outdoors only, away from doors, windows and vents.
