**Enhanced Penetration Force**
Equipped with a powerful 750W servo motor, the MLK-342H delivers strong penetration force even at low speeds, making it ideal for thick materials like leather and heavy fabrics.
---
**Energy Efficiency**
This machine is designed with energy-saving technology, reducing power consumption by about 15% compared to similar models on the market. It combines high-speed performance with low energy usage, making it an eco-friendly choice.
---
**Precise Fabric Positioning**
The dual-step clamp system allows for accurate positioning of fabric, reducing errors and saving time during the sewing process. The clamp can be stopped mid-way and lowered precisely to the desired height.
---
**Easy Pattern Change**
Changing patterns is simple and fast. The clamp can be removed and replaced in seconds, and the feed plate can be easily aligned and secured with bolts. This ensures quick and accurate pattern adjustments.
---
**Large Memory Capacity**
The MLK-342H has a large internal memory capable of storing up to 999 patterns and 500,000 stitches. With SD card and USB support, users can easily transfer and manage data across multiple machines or computers.
---
**User-Friendly Touch Panel**
The LCD touch panel offers intuitive control, allowing operators to monitor sensor inputs, adjust settings, and quickly access frequently used functions. It supports Mitsubishi and Brother pattern interfaces, ensuring compatibility and ease of use.
---
**Low Tension Sewing**
With precise servo control over the feeding device and needle bar, the machine can sew under low tension conditions, maintaining consistent thread tightness and quality.
---
**Perfect Stitch Quality**
Thanks to accurate needle placement and a high-precision feeding system, the MLK-342H produces clean, parallel stitches even at high speeds. It handles thick materials without compromising stitch quality or causing misalignment.
---
**Consistent Bottom Thread Tightness**
Users can easily adjust the pressure foot height based on material thickness, ensuring uniform bottom thread tension and preventing issues like loose or skipped stitches.
---
**Easy Head Adjustment**
The machine head can be adjusted without tilting, thanks to the needle guard mechanism. This makes fine-tuning the needle-to-hook distance quick and convenient.
---
**Clear Field of Vision**
Without a presser foot arm support plate, the machine provides a wide, unobstructed view of the work area, making fabric inspection and positioning more straightforward.
