The Power of Blue®.
Multi-arc welding is here! One dependable engine and two highperformance arcs allow operators to work independent of each other. It’s a one-of-a-kind, go-anywhere engine drive.
Increase profits with this multi-arc machine by completing even your most demanding jobs in half the time compared to conventional engine-driven welders. With two arcs in one engine drive, fewer machines are required for a job.
Double the amperage output with a switch that parallels both outputs to a single side. This provides a safe and easy way to run large electrodes, stud weld, or carbon-arc gouge.
5,500 watts of AC generator power independent of welding output. Two 120 V, 20 A GFCI duplex receptacles. Two 230 V, 20 A duplex receptacles.
Welder/generator is warranted by Miller for 3 years, parts and labor.
Engine is warranted by Deutz for 2 years.
Two 14-pin remote controls can be used for precise adjustment of amperage or voltage along with contactor.
Hot Start™ provides positive stick electrode starts to make it easy to start all types of electrodes.
Weld meters — digital ammeter and presettable voltmeter allow monitoring of welding output for each welder.
Arc control (DIG) allows the arc characteristics to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010 electrodes.
Thermal overload protection prevents machine damage if the duty cycle is exceeded or airflow is blocked.
