The DW200P Micro Spot Welder is a production‑grade spot welding system optimized for speaker coil‑and‑membrane (CCM) assemblies and thin metal sheet welding. It combines a high‑resolution transistor power supply, precise pulse shaping, and a controlled actuator for repeatable micro‑spots. Designed for inline and bench integration, the system supports programmable weld recipes, multi‑pulse modes, optional weld monitoring, and quick electrode changeover for high‑mix speaker production.
Problem: In speaker manufacturing, inconsistent welds on thin metal diaphragms and frames cause poor acoustic performance and high scrap rates.
Cause: Variations come from uncontrolled energy delivery, inconsistent electrode contact force, and inadequate pulse control on conventional welders.
Solution: The CCM welder uses transistor current shaping, sub‑ms pulse control and stable actuator force to apply the minimal required energy for reliable joints while minimizing heat‑affected zones and preserving acoustic properties. Validate recipes via pilot tests and lock them into MES for repeatable production.

Recipe selection: load material preset or create custom profile (current, pulse width, force, pulses).
Electrode contact & force: actuator applies controlled force to ensure stable contact resistance.
Pulse delivery: transistor power supply delivers shaped current pulse(s) per profile.
Cooling & monitoring: integrated cooling reduces accumulated heat; optional weld monitoring logs current/voltage traces for QA.
Target spot size & spot density: select electrode tip diameter and pulse energy to meet spot geometry without overheating adjacent areas.
Material & thickness: confirm recommended thickness range and run a material matrix for pulse tuning.
Force requirement: choose actuator range to ensure stable contact but avoid excess deformation on thin diaphragms.
Throughput: confirm cycle time and actuator speed meet line takt; select model with required PLC/MES I/O.
QA needs: pick the monitoring option if traceability and SPC are required.
Installation: bench or cell mount; connect grounded power, clean compressed air (if pneumatic actuator), and cooling. Follow ESD and handling practices for delicate diaphragms.
Commissioning: perform pilot runs across target materials and thicknesses to create validated recipes.
Maintenance: dress electrode tips regularly; replace worn tips and inspect force sensor calibration monthly in high‑use lines.
Q: What minimum spot diameter can be achieved?
A: Typical minimum spot diameters range 0.2–0.6mm depending on electrode tip and material—confirm with sample tests.
Q: Does the system support multi‑pulse profiles?
A: Yes—single and multi‑pulse modes enable staged energy delivery for fragile substrates.
Q: Can weld data be logged for traceability?
A: Yes—optional weld monitoring records current/voltage traces and exports batch logs for SPC or MES.
