200A connecting rod

The 200A specification gas shielded welding gun connecting rod is a core vulnerable part of welding equipment, used to connect the welding gun neck and 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 200A and avoid affecting welding performance due to overheating or wear.

Structural design: Adopting a threaded connection structure, one end is adapted to the corresponding specification of the welding gun neck, 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 threaded 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 200A gas shielded welding guns (such as some well-known 200A manual welding guns), can be matched with conductive nozzles with diameters of 0.8-1.2mm, meeting the needs of small and medium 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 small and medium current carbon dioxide gas shielded welding (CO ₂/MAG welding) scenarios, such as automotive maintenance, small steel structure processing, equipment component welding, etc., it is a key component of manual gas shielded welding guns and needs to be regularly inspected for wear and replaced in a timely manner.
