350A variable diameter protection nozzle

The 350A variable diameter protection nozzle is one of the core components of the gas shielded welding gun, and its detailed introduction is as follows:

Definition and Function

The 350A variable diameter protection nozzle is designed specifically for gas shielded welding equipment with a rated current of 350A. The "variable diameter" structure can guide the protective gas carefully, forming a stable gas curtain during welding, isolating the interference of external air on the arc and molten pool, and effectively avoiding defects such as pores and slag inclusions, protecting the strength and density of the welded joint.

Material and Craftsmanship

Copper substrate: It has excellent conductivity and thermal conductivity, and can dissipate heat at a suitable speed during high current welding at 350A, preventing deformation or damage due to high temperature and ensuring long-term stable operation.

Chrome plating treatment: The surface adopts chrome plating technology, presenting a bright metallic texture. Not only does it enhance performance and corrosiveness, but it also reduces the adhesion of welding slag, making it easier to clean, while improving the practicality and aesthetics of the product.

structural design

Variable diameter channel: The internal aperture is designed with a gradual gradient, which makes the flow rate and distribution of the protective gas from the inlet to the outlet more uniform, and covers the welding pool more extensively, improving the protective effect.

Connection part: A connection structure with threads or sliding patterns (such as the middle section with patterns in the picture), which can be assembled with a 350A welding gun at a suitable speed and firmly, and is not easy to loosen during the welding process, protecting operational stability.

End design: The end opening is carefully processed to protect the visibility of the arc, making it convenient for welders to observe the molten pool and control the welding process in detail. It also allows the protective gas to form an effective gas curtain, which is suitable for various welding process scenarios.

performance advantage

High temperature resistance (based on actual reports) and deformation resistance: able to withstand the high temperature generated by 350A welding current, not easily deformed after long-term use, confirming the continuity of the protective function.

Good utilization rate of protective gas: The variable diameter design optimizes the gas flow field, making the protective gas more efficiently wrap around the molten pool, especially when welding materials such as carbon steel and stainless steel, which can significantly improve the mechanical properties and corrosion resistance of the welded joint (based on actual reports).

Adaptability and practicality: Suitable for high current welding scenarios such as factory batch welding and steel structure welding. Excellent materials and processes make it have a long service life, reducing the frequency and cost of component replacement.
