500A connecting rod - outer wire

This is a 500A specification gas shielded welding gun outer wire connecting rod, which belongs to the core conductive accessory of high current welding equipment. It is used to connect the welding gun neck and the conductive nozzle seat, realizing synchronous transmission of welding current and welding wire. Its detailed characteristics are as follows:

Material and Structure

Main material: Made of purple copper, which has excellent conductivity, thermal conductivity, and performance. It can stably carry a large welding current of 500A and avoid affecting welding performance due to overheating or wear.

Structural design: Adopting an external thread connection structure, one end is adapted to the neck of the corresponding specification welding gun, and the other end is connected to the conductive nozzle seat; There are multiple heat dissipation holes on the surface to enhance heat dissipation during welding, resulting in excellent performance and prolonging the service life of the components.

performance advantage

Stable current transmission: The purple copper material and tight external thread connection design protect the uniform conduction of welding current to the welding wire, avoiding unstable arc 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.

Strong adaptability: compatible with gas shielded welding guns of 500A specification, can match conductive nozzles with diameters of 0.8-1.6mm, meeting the requirements of large-scale current welding scenarios.

High practicality: Copper components are corrosion-resistant and resistant to high temperatures (based on actual reports), and the threaded structure is fatigue resistant (based on actual reports). They 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 component of the 500A specification gas shielded welding gun and needs to be regularly inspected for wear and timely replaced.
