200A-350A-500A

This is a set of gas shielded welding gun necks that are respectively adapted to current specifications of 200A, 350A, and 500A. They are the core components of welding equipment and are used to connect the welding gun body and the conductive nozzle assembly. Their detailed characteristics are as follows:

Material and Structure

Main material: Made of a combination of copper (front conductive component) and high-temperature resistant (based on actual reports) insulation material (black component). Copper has excellent conductivity and thermal conductivity, and can stably carry welding currents of 200A, 350A, and 500A respectively; Insulation materials are used to isolate welding currents and protect safe operations.

Structural design: It is curved with different curvatures, and the length increases with the increase of current specification, which is convenient for the welding gun to adjust the angle during welding and adapt to different welding positions; One end is connected to the welding gun body through a threaded or snap on structure, and the other end is used to install components such as the conductive nozzle seat and conductive nozzle. The red identification ring and label serve to distinguish specifications.

200A stable current transmission, suitable for small and medium current welding, strong angle flexibility for automotive maintenance, small steel structure processing, etc

350A balances current carrying capacity and operational flexibility, suitable for medium to large current welding steel structure processing, equipment component welding, etc

500A can carry high current, withstand high temperature (based on actual reports) and wear, suitable for industrial grade high-strength welded heavy-duty steel structures, automotive manufacturing production lines, etc

Precautions

According to the current specifications and welding scenarios of the welding equipment, the corresponding model of gun neck should be selected to confirm stable welding current transmission and excellent weld quality. At the same time, the wear and insulation of the gun neck should be regularly checked and replaced in a timely manner to protect welding safety and efficiency.
