Powerful all-in-one tool designed for repair and construction with multiprocess weld quality, auxiliary power, air compressor and battery charge/crank assist.

• Exceptional Arc Performance Easy arc starts and less spatter.
• Easy to Use Digital interface speeds machine setup and makes it less complicated.
• 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 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.
• 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.
• Excel™ power (option) 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.
