Miller Trailblazer 330 EFI, Excel, Polarity Reversal, WIC Remote #907832006
Reliable engine-driven welders with unbeatable arc performance, providing the smoothest, most stable arc in the industry. Trailblazer exclusive technologies — advanced Auto-Speed™ and optional Excel™ power — deliver superior runtimes, increase fuel efficiency, and improve engine-driven welder performance. No other compact machine in the 300-amp class delivers more welding power or more auxiliary power with better fuel efficiency and less noise — for productive, profitable, quieter job sites.
Polarity Reversing Technology
Advanced polarity reversing abilities allow seamless switching between DCEP (DC+) and DCEN (DC-) polarities. This flexibility empowers welders to effortlessly handle diverse welding tasks, ensuring top-notch performance across materials and techniques. With this feature, craftsmen achieve superior penetration or precise filler material deposition, enhancing efficiency and delivering exceptional results.
Excel™ Power
Unlike competitive machines that provide auxiliary power only at 3,600 rpm (max), Excel power delivers a full 2,400 watts (20A) of 120V inverter-based, pure sine wave power at idle. With Excel power, you can operate jobsite tools like grinders and lights at a quieter, fuel-saving engine speed.
Refueling time and operating costs are reduced with Excel power, which means more productivity and profitability. Plus, everyone on the jobsite gets a better working environment because noise levels and exhaust emissions are lowered.

Features of the Trailblazer 330 #907832006:
As with the previous model 211, the updated model has a Multi-Voltage Plug (MVP) that allows you to connect to either 120 or 230 V power receptacles without the use of any tools.
- Intuitive digital interface with Auto-Set™ makes it quick and easy to precisely set weld parameters for any process.
- Lighter and Smaller - The Trailblazer 330 weighs less than any other engine-driven welder in its class. It’s over 80 pounds lighter and 13% smaller than previous models, so it’s easier to move and takes up less space on trucks.
- Advanced Auto-Speed™ technology automatically varies engine speed from 1,800–3,600 rpm to match weld demands — reducing fuel consumption, maintenance costs and noise for a safer, more efficient jobsite.
- Predictive Maintenance
- Direct Connect Spool Gun Connection
- ArcReach® for parameter control at the wire feeder or pendant without needing a control cord.
- Dynamic DIG™ to optimize arc control for stick welding applications.
- Pulsed TIG with QuitePulse™ creates a slower, more fluid transition between background and peak amperage.
- Excel™ Power delivers a full 2,400 watts (20 A) of 120-volt inverter-based, pure sine wave power at all speeds, including idle.
- Polarity reversing capability to easily switch polarity of the weld studs at the interface.
- Wireless Interface Control so you get full control of your machine in the palm of your hand, from wherever you are on the jobsite, so you can work hassle free.
