Precision Transistor Welding Power Supply for Fine Wire & Thin Metal Welding
The JMS1000A is a vertical-format, closed-loop transistor-type welding power supply engineered to deliver ultra-stable, high-frequency energy output for enameled wire welding, thin metal sheet bonding, and plastic column thermal riveting processes. Purpose-built for the precision electronics sector, this system is ideal for applications requiring tight thermal control, minimal heat spread, and reliable weld consistency on small, delicate workpieces.
Combining a fast response time of 0.5ms with a high switching frequency of 100–150 KHz, the JMS-1000A ensures quick and stable discharge, effectively minimizing thermal damage to heat-sensitive substrates such as FPC boards or thinly plated pads.
Key Advantages
- Ultra-Fast Discharge: Reaches stable output in just 0.5ms, minimizing heat diffusion and preventing damage to thin plating or small pads.
- High Switching Frequency: Operates at 100–150 KHz with fine timing control down to 0.01 ms for precise energy management.
- Real-Time Welding Quality Monitoring: Simultaneous display of current, voltage, resistance, power, and heat enables immediate quality checks and data logging.
- Flexible Control Modes: Supports constant current, constant voltage, or mixed-mode operation to suit various process requirements.
Typical Application Fields
✓ Enameled wire welding for micro coils and sensors
✓ Thin copper or tin pad spot welding
✓ Plastic column thermal riveting for lightweight electronics housings
✓ FPC (Flexible Printed Circuit) pad welding
✓ Precision bonding for heat-sensitive substrates and fine metal contacts

Q&A
Q1: Why choose JMS1000A for delicate pad and FPC welding?
A: It's fast discharge and precise energy control prevent overheating, ideal for thin plating and substrates with low thermal tolerance.
Q2: Can I adjust the control mode for different materials?
A: Yes. You can switch between constant current, constant voltage, or hybrid mode to adapt to different wire types, pad sizes, or substrate conditions.
Q3: How does the real-time waveform display help?
A: It lets you monitor actual current, voltage, and heat in every weld cycle, so operators can spot abnormal conditions immediately and adjust settings to maintain high quality.
Q4: Is it suitable for automation?
A: Absolutely. With its RS485 interface, the JMS-1000A can be easily connected to a PLC or MES for remote monitoring, data logging, and integration into modern smart production lines.
