480.00 $
The USB Soldering Machine JA-SD205H is a 24 V automatic soldering machine with a 160 W high-frequency station for multi-wire welding of connectors and harnesses. Stepper-motor tin feed keeps every joint consistent in 24-hour operation. Part of our Desktop Soldering Machine range.
Key Features
- 24-Hour Continuous Operation: Built for high-volume production lines with uninterrupted runtime support.
- 160W High-Frequency Soldering Station: Delivers rapid heat recovery and precise temperature control for consistent weld quality.
- Stepper Motor Tin Feed (376D): Ensures identical solder wire length from first to last — no flow reduction, no inconsistency.
- 4-Position Digital Display: 5-inch green screen — clear, real-time parameter monitoring at a glance.
- Low Standby Power: Welding station standby at 3W; whole machine standby at 13W — significantly lower than market alternatives.
- Dual Tin Dispensing Modes: Pre-dispense before soldering, or dispense during contact — selectable by working mode.
- Flexible Solder Nozzle Positions: Rear delivery, left delivery, or fixed bottom — adaptable to your fixture setup.
- Dual Head Support: Optional dual-head configuration available for long-distance or simultaneous soldering.
- USB Work Light Included: High-brightness USB work light (5V/1A charging port) included as gift.
Product Description
The JA-SD205H is a high-performance, 24V automatic soldering machine engineered for precision multi-wire welding in industrial production lines. Equipped with a dedicated 160W high-frequency CNC soldering station, it delivers consistent, repeatable solder joints across a wide range of components — from connectors and terminals to circuit boards and wiring harnesses. Designed for 24-hour uninterrupted operation with easy parameter control and low operator skill threshold.
By using a precision stepper motor tin control system, the JA-SD205H eliminates the inconsistency of manual soldering while keeping operating costs and noise levels low. The machine supports solder wire diameters from 0.5mm to 1.2mm (1.5mm and 2.0mm available on custom order), with a dedicated nozzle for each gauge to ensure clean, jam-free feeding every cycle.
With manual height and width stroke adjustment (0–50mm range), it adapts quickly to different product batches without tooling changes. A built-in equipotential grounding hole protects sensitive ESD-rated components during the welding process.
