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 jobsites.

• Exceptional Arc Performance: Easy arc starts and less spatter.
• Easy Maintenance: With its intuitive design, the daily maintenance of our engine-driven welder is fast and easy.
• Auto-Speed™ technology: Advanced Auto-Speed technology automatically adjusts engine speed to match weld and battery charge demands — reducing fuel consumption, maintenance costs and noise for a safer, more efficient jobsite.
• Easy to Use: Digital interface speeds machine setup and makes it less complicated.
• Separate weld and auxiliary power: Full auxiliary power at any setting.
• QuietPulse™: QuietPulse is activated by changing the waveshape for DC pulse welding, creating a slower, more fluid transition between the background and peak amperage to create the least possible audible noise.
• Dynamic DIG™: Unlike conventional DIG that provides a preset amount of short-clearing current, Miller’s proprietary Dynamic DIG works on a time-based algorithm that automatically adjusts the amount of current required to clear a short. What does this mean? A smoother more consistent arc that can be tailored to match application, material, fit-up, and welder technique.
• ArcReach® Technology: ArcReach technology uses existing weld cables to communicate process adjustment commands back to the engine-driven welder. With an ArcReach system, amperage & voltage are conveniently located at the operator's fingertips - not back at the power source.
