More Information

Easy to Use

Digital interface speeds machine setup and makes it less complicated.

Exceptional Arc Performance

Easy arc starts and less spatter.

Easy Maintenance

With its intuitive design, the daily maintenance of our Trailblazer engine-driven welder is fast and easy.

Easier mobility and uses less truck space and payload

Over 80 pounds lighter and 13 percent smaller than previous models.

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.

Separate weld and auxiliary power

Full auxiliary power at any setting.

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.

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.


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.
