Features

Easy to Use
Digital interface speeds machine setup and makes it less complicated.   Learn More
Exceptional Arc Performance
Easy arc starts and less spatter.
Rotary Screw Compressor
Quiet and durable rotary-screw compressor delivers 30 CFM at 80-160 psi of air at 100% duty cycle while rated at 104° F.  It offers an average of three times the service life of traditional reciprocating compressors. Produces air when you need it; no more down time waiting for an external tank to fill. Airflow can be selected depending on tool requirements. Front panel air pressure adjustment makes it simple to dial in the correct air pressure for specific applications (80-160 psi)
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 180 pounds lighter and 13 percent smaller than previous models.
Battery charge/crank assist
Machine provides up to 150 amps of DC power to quickly charge 12- and 24-volt batteries. Jobsite equipment with weak batteries can get up to 300 amps of crank assist power.
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.   Learn More
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.   Learn More
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.   Learn More
Excel™ power
Power at idle — a Miller exclusive. Unlike competitive machines that provide auxiliary power only at 3,600 rpm (max), Excel power delivers a full 2,400 watts (20 A) of 120-volt inverter-based, pure sine wave power at all speeds, including idle. With Excel power you can operate jobsite tools like grinders at quiet, fuel-saving speeds. 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. Excel power — available only from Miller.   Learn More
