Multi-arc welding is better than ever!
One dependable engine with two
premium pipe-quality arcs, allow
operators to work independently of
each other with no arc interaction. Full
multiprocess capability provides the
best Stick, MIG, Flux-Cored and TIG
performance available. Multioperator
welding was never easier, simpler or
more versatile. It’s a one-of-a-kind, go-anywhere engine drive.
The Professional Welder’s Choice—
designed with the professional in
mind, the Big Blue 700 Duo Pro is the
best for arc performance, ease of use and reliability.
Double the amperage output. Deluxe
models have a parallel switch that
combines both independent outputs to
a single side. This provides a safe and
easy way to run large electrodes, Stud weld or Carbon Arc gouge.
Increase profits with this multi-arc
machine by completing 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.
Thermal overload protection prevents
machine damage if the duty cycle is
exceeded or airflow is blocked.
Standard features include: Stick, MIG, Flux-Cored,
Lift-Arc™ TIG, and digital preset weld meters,
output contactor control and automatic idle.
