24KD protective nozzle

24KD protective nozzle is a commonly used accessory in carbon dioxide gas shielded welding, mainly used to protect the welding area and conductive nozzle. Here is a detailed introduction about it:

Suitable welding gun models: mainly compatible with the European gas shielded welding gun of Binzel 24KD model, and also compatible with 15AK, 25AK, 36KD, 501D and other series of welding guns.

Material and Performance: Common materials include brass and purple copper. The 24KD protective nozzle made of brass material has good economy and is suitable for conventional welding current; Copper material has good conductivity and high temperature resistance (based on actual reports), can withstand large currents, and has a relatively long service life. In addition, there are some protective nozzles that have undergone coating treatment and have the characteristic of not sticking to welding slag, which can reduce the number of cleaning times and improve work efficiency.

Size specifications: There are usually multiple specifications to choose from, commonly including inner diameters of 1.0mm, 1.2mm, 1.5mm, 2.0mm, etc., to accommodate welding wires of different diameters, such as 0.8mm, 1.0mm, 1.2mm, etc.

Function: Its main function is to isolate splashes generated during the welding process, prevent them from adhering to the conductive nozzle, and affect the conduction of welding current. At the same time, it can also guide the protective gas to evenly cover the welding area, avoiding oxygen and nitrogen in the air from oxidizing the molten pool, thereby protecting the quality of the weld.
