JACK A4C C Single Needle Direct Drive Fully Automatic Drop Feed Lockstitch Industrial Sewing Assembled with Table and Stand Included

Key Features

• NTB System with Octopus Nine‑Brain AI Chip: Processes over 200,000 fabric samples at 10,000 computations per second to dynamically adjust feed force and synchronize thread-taking, catching, and fabric feeding.
  
  
• 0‑Degree Thread Path Technology: Significantly reduces thread tension by up to 30%, minimizing friction and breakage.
• Stepper Motor for Presser Foot Lift and Reverse: Ensures exceptionally quiet operation and smooth control, carried over from the A4B-C design.
  
  
• Direct‑Drive, Energy‑Saving Motor: Built-in, quiet, and efficient for smooth, power-saving operation.
  
  
• Automatic Sewing Functions: Includes thread trimming, foot lift (up to 13 mm), back‑tacking, and needle up/down positioning for streamlined, operator-friendly performance.
  
  
• Enhanced Usability Features: LED lighting for better visibility and optional voice feedback to guide operation.
