This semi-automatic soldering system offers a versatile and accurate solution for wire-to-PCB and wire-to-connector soldering tasks. Specifically developed for electronics assembly, cable harness production, and connector fabrication, it consistently delivers high-quality soldering results while easing operator effort and boosting overall throughput.
The equipment comes with programmable soldering parameters, including temperature regulation, adjustable soldering duration, and controlled solder wire feeding length. Its intuitive digital interface enables operators to create, save, and quickly switch between multiple programs, making it adaptable to diverse wire diameters and component types.
It supports reliable soldering of a wide variety of electronic components such as circular connector contacts, male and female terminals, USB and DC jacks, Type-C charging ports, toggle switches, and aviation plugs. The machine ensures stable and precise results when processing socket contacts, crimp terminals, and various insert pins commonly found in aerospace and industrial electronics.
Custom fixtures can be configured for different connector categories—including header pins, three-pin plugs, receptacle contacts, voltage regulator modules, and terminal pins—allowing the same machine to accommodate multiple connector families. Both plug and socket interfaces are supported, providing excellent adaptability across different electrical connection requirements.

With automatic solder wire feeding and precise soldering control, the system minimizes operator dependency while guaranteeing repeatable, efficient results. This ensures consistent quality in soldering connector pins, sockets, and detachable contacts, making it well-suited for volume production environments.
Combining automated processes with flexible manual handling, this semi-automatic soldering machine improves productivity, reduces defects, and secures reliable electrical performance for demanding sectors such as automotive, aerospace, telecommunications, and industrial electronics.
