Data from official source
The Triumph is Baby Lock's flagship serger: it sews from 2 to 8 threads on the same machine body, combining overlock and cover-stitch, with 5 needles and RevolutionAir air threading on both loopers and needles — two buttons, no chasing thread. The Automatic Thread Delivery system works out tension on its own and keeps it set even when the order you thread the loopers in changes.
Stitch width runs from 1.5 to 7.5mm (up to 16mm on decorative stitches) and length from 0.75 to 4mm, both set with a dial; the two-thread rolled-hem converter is automatic, with no plate to remove. The knee lift frees both hands for the presser foot, which is pressure-adjustable and lifts up to 6mm.
It's a combo machine: switching from overlock to cover-stitch still means a physical conversion of the machine (needle, plate, foot), not a simple program change.

02 · Summary
Pros and cons
In favour
- Air threading reaches loopers and needles with two buttons, even with 5 needles to manage
- It sews overlock and cover-stitch on the same machine body, from 2 to 8 threads
- The knee lift frees both hands for the presser foot while you work
- Tension sets itself with the Automatic Thread Delivery system
Worth knowing
- Switching from overlock to cover-stitch still needs a physical conversion of the machine, not a program change source
- With 5 needles and more thread configurations, initial setup asks for more attention than a simple 2-needle overlock
