Secondary welding assembly cable socket

The secondary welding assembly cable socket is a key accessory used for cable connection in carbon dioxide gas shielded welding (secondary welding) equipment. Its core function is to achieve integrated connection of welding current, wire feeding motor control line, and protective gas pipeline, protecting the stable operation of the welding process. The following provides a detailed explanation from the aspects of structure, material, performance, and application:

structural design

Multi interface integration: Usually integrates welding current interface (copper conductive parts), wire feeding motor control interface (signal transmission terminal), and protective gas interface (gas path) to achieve "electric gas control" integrated connection, reduce cable clutter, and improve operational safety.

Prefabricated module: adopting modular design, each interface can be independently disassembled and maintained. For example, after the conductive module wears out, only the corresponding components need to be replaced, without the need to replace the socket as a whole, reducing the cost of use.

Quick plug/locking structure: The current interface is mostly quick plug type (such as the European DKJ series), and the connection is confirmed to be firm with the locking design to avoid poor contact caused by vibration during welding; The gas interface adopts threaded or quick plug sealing connection to prevent gas leakage.

Material and Craftsmanship

Conductive components: The core conductive part is made of high-purity copper (purity ≥ 90%), with an IACS conductivity of ≥ 90%, capable of withstanding welding currents above 350A. It has been confirmed that the current transmission loss is small and the arc is stable.

Insulation and shell: The shell is made of high temperature resistant (based on actual reports) insulating rubber (black or red to distinguish positive and negative poles), which has excellent insulation performance and can withstand high temperatures (≤ 150 ℃) and spark splashes in welding environments; The gas passage components are made of brass, which combines sealing and corrosion resistance (based on actual reports).

Careful processing: The conductive contacts are processed by CNC, with a contact resistance of ≤ 0.1m Ω, and the current transmission efficiency is confirmed; The precision of the gas interface sealing surface is controlled at ± 0.02mm to avoid gas leakage affecting the protection effect.

performance advantage

Stable current transmission: Made of purple copper material and designed with low contact resistance, it can stably transmit high currents (350A-500A), avoiding arc instability and weld defects caused by poor contact.

Gas electric synchronous protection: The integrated design confirms the synchronous start/stop of welding current, wire feeding control, and gas protection, improving the coordination of the welding process, especially suitable for automated secondary protection welding equipment.

Strong practicality: Copper conductive components are wear-resistant (based on actual reports), high temperature resistant (based on actual reports), and have aging insulation rubber. The overall service life is extended by more than 30% compared to ordinary split sockets.

Specifications and Applications

Adaptation specifications: The mainstream adaptation cable specifications are 35-50mm ² (current interface), gas interfaces are mostly M10/M12 threaded or quick plug type, and signal interfaces are aviation plug type (such as 4-core/6-core).

Application scenarios: Widely used in industrial grade secondary welding equipment (such as NB-350, NB-500 welding machines), cable connections for automated welding robots, especially suitable for high current, high cycle production scenarios such as steel structure manufacturing and automotive parts welding.

Precautions

During installation, it is necessary to confirm the corresponding connections of each interface (current, signal, and gas interfaces should not be confused) to avoid equipment damage or welding failures.

Regularly check the sealing of gas interfaces, clean the oxide layer of conductive contacts, and confirm stable gas electric transmission.

Choose sockets that match the welding machine and welding gun models (such as European/Japanese interface differences) to avoid compatibility issues.
