The 15AK protective nozzle is the core accessory of European gas shielded welding guns (especially suitable for the Binzel 15AK/14AK series), mainly used for carbon dioxide gas shielded welding (secondary protection welding). By isolating splashes and guiding the protective gas to evenly cover the welding area, it protects the stable transmission of welding current and the quality of the weld seam. It is widely used in industrial manufacturing and maintenance scenarios.
2、 Core functions and advantages
Protection of welding area: Isolate the splashes generated during the welding process to prevent them from adhering to the conductive nozzle or welding area, while preventing the leakage of protective gas and reducing the oxidation of the molten pool by oxygen and nitrogen in the air, making the weld smoother and free of porosity defects.
Stable current transmission: In conjunction with the conductive nozzle, the excellent conductivity of copper material protects the stable transmission of welding current, reduces voltage fluctuations, makes the welding process smoother, and enhances the consistency of weld formation.
Strong practicality: The purple copper material has excellent high-temperature resistance (based on actual reports) and is not easily deformed even after long-term high-temperature operation; The coated version also has the characteristic of not sticking to welding slag, making cleaning more convenient and extending the service life.
Easy installation: Adopting a buckle or threaded design, it can be easily installed and disassembled without the need for specialized tools, and is suitable for different scenarios such as on-site maintenance and mass production.
3、 Applicable scenarios
Adaptation process: Carbon dioxide gas shielded welding (double protection welding), MIG welding (melting electrode gas shielded welding).
Application industries: automobile manufacturing, steel structure processing, hardware parts production, pipeline welding, equipment maintenance, etc; Especially suitable for medium and light welding operations with high requirements for weld quality, such as thin plate splicing, frame welding, etc.
Operating environment: Suitable for both batch production in the workshop and outdoor on-site construction, suitable for AC220V/380V conventional industrial welding machine power supply scenarios.
4、 Precautions for selection and use
Model matching: It is necessary to confirm that the welding gun model is 15AK/14AK European interface to avoid confusion with other models of protective nozzles such as 24KD and 36KD (different interface specifications cannot be used interchangeably).
Material selection: For regular current (≤ 150A) operations, brass options are available (with good cost-effectiveness); It is recommended to choose copper for high current (150A-250A) or long-term operation (high temperature resistance (based on actual reports), long service life); Priority should be given to coating anti sticking products for scenes with more splashes.
Size adaptation: Select the protective nozzle with the corresponding aperture according to the diameter of the welding wire (such as adapting 1.0mm welding wire to 1.0mm specification protective nozzle), to avoid wire feeding jamming or uneven coverage of protective gas caused by mismatched aperture.
Daily maintenance: Clean the welding slag on the inner wall of the protective nozzle in a timely manner after welding to prevent blockage of the airway; Replace the protective nozzle in a timely manner when deformation, damage, or coating detachment is found to avoid affecting the welding quality.
Price reference: The individual price is about 2-32 yuan (due to differences in material, reputation, and packaging), and bulk purchases (≥ 200 sets) can be as low as 5.9 yuan/set or less.
5、 Common supporting accessories
The 15AK protective nozzle is often used in conjunction with the same series of conductive nozzles, connecting rods, splitters, bent pipes, and other accessories to form a complete welding gun gas path and circuit transmission system. When selecting, it can be replaced as a set according to wear and tear to confirm the overall stability of the welding gun performance.
