Welding machine can combine independent welding outputs for 800 amps

Miller Electric Mfg. Co. has introduced the new Big Blue® 700 Duo Pro, a diesel engine-driven welding machine and AC generator that offers independent multiarc 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 800 amps of welding power for running large electrodes, stud welding, and carbon arc gouging (up to 0.375-in. carbons).

Offering multiprocess capabilities (SMAW, GMAW, FCAW, GTAW, and carbon arc gouging), the welding machine offers two independent generator outputs. One 5,500-W-peak/4,000-W-continuous, single-phase generator is fully independent of weld output. The second generator provides 27,000-W-peak and 20,000-W-continuous power.
