Why the Big Blue 700X Duo Pro Is the Best Upgrade from the Big Blue 600X

Looking to maximize productivity without doubling your expenses? Let’s compare the Big Blue 700X Duo Pro and the Big Blue 600X CC to see why the Duo Pro is the smart choice for high-demand welding environments.

Same Engine, Lower Cost Per Arc

Both the Big Blue 700X Duo Pro and Big Blue 600X CC are powered by the same Deutz engine. That means maintenance costs, like labor, oil filters, and oil changes, remain the same. But here’s the difference: with Big Blue 700X Duo Pro, you get two arcs from a single engine, cutting your operational cost per arc in half.

More AUX Power for the Field

• Big Blue 700X Duo Pro:
  • One 3Ø outlet: 20kW
  • Four 1Ø outlets: 12kW total
• Big Blue 600X CC: Lower total AUX output, limiting flexibility for jobsite tools and equipment.

More Welding Options, Higher Productivity

The Big Blue 700X Duo Pro supports a wider range of welding processes and delivers a strong duty cycle, perfect for demanding operations that require flexibility, uptime, and performance.

Fuel Savings: See the Difference

Even with dual-arc output, the Big Blue 700X Duo Pro consumes far less fuel compared to running two Big Blue 600X units.

That’s a 33% savings in diesel per year while still powering two welding arcs!

Compact Yet Powerful

Despite its advanced capabilities, the Big Blue 700X Duo Pro shares the same external dimensions as the Big Blue 600X, saving you space on-site or in transport without compromising performance.

Why Choose BB700X Duo Pro?

• Dual arc from one machine
• Significant fuel savings
• More AUX power and welding process options
• Same maintenance cost and compact footprint
