welding nozzle
The protective nozzle is a key accessory of a CO2 gas shielded welding torch. Its main function is to guide the shielding gas to evenly cover the welding area, prevent oxidation of the molten pool, and protect the contact tip from high temperatures and weld slag damage.
Core Function: The protective nozzle is installed at the front end of the welding torch. It delivers carbon dioxide or a mixed protective gas evenly to the welding area through the nozzle, isolating the weld from air and preventing oxidation, while also reducing damage to the contact tip from spatter.
