350A-500A all copper

This is a set of 350A-500A specification gas shielded welding gun all copper insulation sleeves (conductive connecting components), which are the core accessories of high current welding equipment, used to achieve insulation isolation and stable connection of the welding gun conductive system. Its detailed characteristics are as follows:

Material and Structure

Main material: Made of all brass, it has excellent conductivity, thermal conductivity, and mechanical strength, and can stably carry large welding currents of 350A-500A, avoiding the impact of overheating or poor contact on welding performance.

Structural design: Integrated insulation sealing components (black rubber or insulating plastic) are used to isolate conductive components from the welding gun housing and protect electrical safety; The surface is designed with sliding and rolling patterns for easy manual tightening during assembly, ensuring tight and secure connections.

performance advantage

Stable current transmission: The low resistance characteristics of all brass material protect the uniform conduction of welding current to the welding wire, avoiding arc instability or weld defects under high current, and adapting to the high current welding needs of various welding wires such as carbon steel, stainless steel, aluminum alloy, etc.

Excellent insulation: The matching insulation sealing components can effectively isolate the welding current from the welding gun casing, prevent leakage risks, and protect the safety of operators.

High practicality: brass components are corrosion-resistant and resistant to high temperatures (based on actual reports), the insulation and sealing parts are aging resistant and wear-resistant, and are not easily damaged in high-frequency and high current welding operations, reducing the frequency of component replacement.

Application scenarios

Widely used in industrial grade high current carbon dioxide gas shielded welding (CO ₂/MAG welding) scenarios, such as heavy-duty steel structure processing, automotive manufacturing production lines, large equipment welding, shipbuilding, etc., it is a key conductive insulation component of the 350A-500A specification gas shielded welding gun, which needs to be regularly checked for connection sealing and insulation performance and replaced in a timely manner.
