🧰 Miller Trailblazer® 330 Engine-Driven Welder – Kohler w/ Excel™ Power (907831001)

The Miller Trailblazer 330 (907831001) adds Miller’s exclusive Excel™ Power to the proven 330-amp platform. You get the smooth Trailblazer arc plus a game-changing ability to supply 2,400 watts of 120V, pure sine-wave power at idle. That means you can run grinders, lights, chargers, and other tools quietly at low RPM—cutting fuel use, noise, and emissions while extending engine life.
Under the hood is a dependable 23.5 HP Kohler gasoline engine with Advanced Auto-Speed™—the machine automatically adjusts between ~2,400–3,600 rpm to match load, keeping things quiet and efficient. The latest design is ~80 lb lighter and ~13% smaller than previous Trailblazers, freeing up truck-bed space and simplifying installs.
A modern digital interface speeds setup and gives clear output/maintenance readouts, and the 330 platform supports ArcReach® so you can adjust parameters from the weld joint through the leads—no control cord required. Meanwhile, you still have full generator muscle on tap: 12,000 W peak / 10,500 W continuous to run big tools while you weld.
Process coverage is complete—Stick (SMAW), DC TIG (GTAW), MIG (GMAW), Flux-Cored (FCAW), and CAC-A up to 1/4″ carbons. The platform also offers direct-connect spool-gun capability for fast aluminum MIG with no external control box.
