Is the air threading worth it over a manual serger?

If looper threading is what puts you off serging, yes. The air system threads the loopers with a puff of air, and the built-in needle threader handles the needles. Manual sergers cost less but demand more patience at setup.

Can it sew heavy fabrics like denim?

Yes. PFAFF rates it for heavy material and says it keeps full piercing power at all speeds. Use the heavier HAx1 SP#14 needle for denim and the #11 for fine fabrics.

Does it have automatic tension or a thread cutter?

No to both. Tension is adjusted manually with dials, and you trim threads yourself. Rivals at the top of the range add these, but they add complexity and cost too.

What stitches can it do?

It offers 15 stitches across two needles, covering standard overlock, rolled hem and gathering. Differential feed lets you set the ratio for stretch or for automatic gathering.

What comes in the box?

The machine, foot control, cover, accessory box, double-ended wrench and 20 accessories. Needles are the HAx1 SP type in sizes 11 and 14.

Up to 1300 stitches per minute. That is fine for home garment sewing but slower than high-end sergers aimed at production work.
