Lay-in Tension Threading

With this useful function, Janome takes some of the pain out of threading the bottom looper. While threading, the left side of the machine opens for convenient access and viewing.

A pre-tension slider control is included in the function, allowing you to thread it in seconds.

Adjustable Differential Feed

On all sorts of textiles, the differential feed eliminates the inconvenient puckering or stretching. With a simple turn of the control dial, you can find the ideal setting for your needs.

The differential feed dogs will keep the cloth flowing effortlessly and smoothly beneath the needles to avoid errors. A broad adjustable ratio of 0.5 mm to 2.2 mm is included.

Retractable Upper Knife

The top knife is readily removable, allowing you to serge clothes or projects without having to clip the raw edges. Threading is also easier and safer with this function, especially when using a serger for the first time.

To retract the blade lower and out of sight, open the door to the left of the throat plate, press the control knob, and rotate it.

The cutting width of the knife may be changed from 3 mm to 5 mm when working on textiles that require edge trimming.


The Janome Harmony 7933 comes with a 25-year mechanical parts guarantee, a 2-year electrical component warranty, and a one-year labor warranty.

The Verdict

The Janome Harmony 7933 is a quiet, well-designed machine with some of the greatest entry-level serger capabilities.

Janome assures that owners will not outgrow this serger by providing a broad selection of helpful attachments that will enhance your skills and the machine’s serging capabilities, in addition to being very easy to operate.

This low-cost home serger is just another reason why Janome continues to be a market leader in the serger business.
