The Power of Blue.  
Multi-arc welding is here! One  
dependable engine and two high-  
performance arcs allow operators  
to work independent of each other.  
It’s a one-of-a-kind, go-anywhere  
engine drive.  
Two 14-pin remote controls can  
be used for precise adjustment  
of amperage or voltage along  
with contactor.  
Hot Startprovides positive stick  
electrode starts to make it easy  
to start all types of electrodes.  
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.  
Weld metersdigital ammeter  
and presettable voltmeter allow  
monitoring of welding output for  
each welder.  
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.  
Arc control (DIG) allows the arc  
characteristics to be changed for  
specific applications and electrodes.  
Smooth running 7018 or stiffer,  
more penetrating 6010 electrodes.  
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.  
Thermal overload protection  
prevents machine damage if the  
duty cycle is exceeded or airflow  
is blocked.  
Welder/generator is warranted by Miller for 3 years, parts and labor.  
Engine is warranted by Deutz for 2 years.
