Multi-Operator Welder, AC Generator is driven by diesel engine.
December 5, 2011 -
Big Blue® 700 Duo Pro offers 2 independent welding arcs up to 400 A, without any interaction between them, and ability to parallel both to create 800 A of welding power. One 5,500 W peak/4,000 W continuous single-phase generator output, fully independent of weld output, offers peak performance even when welding at 700 A, and second output is rated at 27,000 W peak/20,000 W continuous. Multiprocess capabilities include stick, MIG, flux cored, TIG, and carbon arc gouging.

Miller Introduces the Big Blue® 700 Duo Pro: a Powerful New Diesel Engine-Driven Multi-Operator Welding Generator
New machine offers either independent dual-operator capabilities with up to 400 amps of welding power or the ability to combine both outputs for up to 800 amps with a single operator. Ideal for work in transmission pipeline, process pipe, construction and MRO welding applications, the Big Blue 700 Duo Pro also offers independent generator power for use of power tools and accessories on site without interacting with the welding arc.
APPLETON, Wis., - Miller Electric Mfg. Co. introduces the brand new Big Blue® 700 Duo Pro, a diesel engine-driven welder and AC generator that offers powerful, independent multi-arc welding in transmission pipeline, process pipe, construction and MRO welding applications. The machine offers two independent welding arcs up to 400 amps (no interaction between the arcs), and the ability to parallel both independent welding outputs to create an extremely powerful 800 amps of welding power for running large electrodes, stud welding and carbon arc gouging (up to 3/8-inch carbons).
Offering full multiprocess capabilities (Stick, MIG, Flux Cored, TIG, Carbon Arc Gouging), the Big Blue 700 Duo Pro also offers two independent generator outputs. One 5,500-watt-peak/4,000-watt-continuous single-phase generator is fully independent of weld output and offers peak performance even when welding at 700 amps (no interaction between arc and generator). The second generator (27,000 watts peak/20,000 watts continuous) provides more robust power for high power needs on site.
Multi-Operator System Improves Productivity, Reduces Equipment Costs
The benefit of a multi-operator system like the Big Blue 700 Duo Pro exists in its ability to provide two high-quality welding arcs in one engine-driven unit. This allows you to get the work of two machines done with one (two operators use one machine). An example would be in transmission pipeline welding applications where two welders work simultaneously down opposite sides of a single pipe. In addition to the equipment cost savings of one machine compared to two, the Big Blue 700 Duo Pro uses an estimated 58-percent less fuel than two single-operator units with comparable engine power. It's also easier to transport, produces less noise and fewer emissions compared to two separate machines.
Powered by Deutz's D2011 L04 4-cylinder heavy-duty, low-speed diesel engine, the Big Blue 700 Duo Pro is designed to operate for 10,000 hours before its first basic overhaul. The machine is EPA Tier 4i compliant, runs at a low 1,800 rpm, and is considerably quieter than most comparable machines-rated at just 75 dB at 23 feet under full load. The machine is also 11-percent smaller and 15-percent lighter than Miller's previous dual operator system in this size class.
Excellent Arc Performance in Stick/TIG/Wire Applications
The Big Blue 700 Duo Pro offers excellent Stick performance, even with difficult electrodes such as E6010. The Hot Start(TM) function provides positive Stick electrode starts with all electrode types. Adjustable arc control allows the operator to adjust DIG, which determines how much the amperage varies with arc length. As more industries-such as transmission pipeline construction-begin to move to higher-strength steels, Miller has also enhanced the MIG and Flux Cored abilities of the machine. Matched with a heavy duty Miller SuitCase® X-TREME(TM) 8HD wire feeder, the machine easily runs all wires from .023-inch solid wires up to large diameter 5/64-inch Self-Shielded Flux-Cored wires. In wire applications, the adjustable arc control allows the operator to adjust inductance to control the wetness of the weld puddle. The machine also offers Lift-Arc(TM) TIG with Auto-Stop(TM) functionality, which eliminates sticking, reduces electrode and workpiece contamination, maintains shielding gas coverage and eliminates arc strikes outside of the work area in TIG applications.
The machine is compatible with Miller's advanced wireless remote control technology and features Auto Remote Sense (ARS), which eliminates the confusion of a remote/panel switch. It also features easy-to-access maintenance points and an extensive meter maintenance display panel for monitoring regular service items. Rated for all outputs at 104 degrees Fahrenheit, the machine is built to weld all day and withstand the rigors of welding outdoors and in rough, dirty climates.
