350A connecting rod inner wire

The internal wire connecting rod of the 350A gas shielded welding gun is a core conductive component of welding equipment, used to connect the neck of the welding gun to the conductive nozzle seat, achieving 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 welding current of 350A and avoid affecting welding performance due to overheating or wear.

Structural design: Adopting an internal 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 heat dissipation holes on the surface to assist in heat dissipation during welding and extend the service life of the components.

performance advantage

Stable current transmission: The copper material and tight internal thread connection design ensure that the welding current is evenly transmitted to the welding wire, avoiding unstable arc or weld defects, and adapting to the welding needs of various welding wires such as carbon steel and stainless steel.

Strong adaptability: compatible with gas shielded welding guns of 350A specification, can match conductive nozzles with diameters of 0.8-1.6mm, meeting the requirements of medium and large current welding scenarios.

High practicality: Copper components are corrosion-resistant and resistant to high temperatures (based on actual reports), thread structures are fatigue resistant (based on actual reports), and are not easily damaged during conventional welding operations, reducing the frequency of component replacement.

Application scenarios

Widely used in medium to large current carbon dioxide gas shielded welding (CO ₂/MAG welding) scenarios, such as steel structure processing, automotive manufacturing, equipment component welding, etc., it is a key component of gas shielded welding guns and needs to be regularly inspected for wear and replaced in a timely manner.
