🧰 Miller Trailblazer® 330 Engine-Driven Welder – Kohler EFI w/ Excel™ Power, Battery Charge/Crank Assist & Wireless Interface Control (907832004)

The Miller Trailblazer 330 (907832004) delivers outstanding welding capability and powerful auxiliary output all in one fuel-efficient design. Built for service-truck operators, mobile field technicians and high-demand applications, this model combines EFI (Electronic Fuel Injection), Excel™ Power, Battery Charge/Crank Assist and Wireless Interface Control (WIC) for unmatched job-site control, power and productivity.
At its core is a robust 23.5 HP Kohler gasoline engine featuring EFI and Miller’s Advanced Auto-Speed™ control, which dynamically adjusts RPM between roughly 2,400 and 3,600 based on load. This means quieter operation, lower fuel consumption, and longer engine life—with full welding and generator output when you need it.
With Excel™ Power, you gain up to 2,400 W of 120 V pure sine-wave auxiliary power at idle, ideal for tools, lights or chargers without revving the engine. The built-in Battery Charge/Crank Assist capability provides approximately 150 A battery charging and up to 300 A crank assist, allowing you to keep fleets and equipment moving in the field.
The Trailblazer 330 platform provides up to 330 A DC weld output and up to 12,000 W peak / 10,500 W continuous generator output—giving you the muscle to weld and run tools simultaneously. It supports full multiprocess welding—Stick (SMAW), DC TIG (GTAW), MIG (GMAW), Flux-Cored (FCAW) and Air Carbon Arc (CAC-A)—with a digital interface, built-in ArcReach® capability, and direct-connect spool-gun compatibility for aluminum MIG.
🔧 Key Highlights
- EFI (Electronic Fuel Injection) — fast starts, no choke, smoother operation and high-altitude capability.
- Excel™ Power — up to 2,400 W (20 A) of 120 V pure sine wave power at idle for tools and lights.
- Battery Charge/Crank Assist — approx. 150 A charge and 300 A crank assist to jump batteries or start equipment in the field.
- 330 A DC weld output — professional-grade welding across all major processes.
- 12,000 W peak / 10,500 W continuous generator power — run tools, lights and weld at the same time.
- Wireless Interface Control (WIC) — remote start/stop, parameter adjustment, preset selection up to 300 ft away.
- ArcReach® compatibility — adjust weld amps/volts at the weld leads, no control cable required.
- Direct-connect spool-gun capable — simplified aluminum MIG setup with no external control box.
- Compact & lighter than previous models — easier installation and increased productivity.
