The structure of the carbon dioxide gas welding nozzle

摘要

The present invention is to more fully present invention relates to a nozzle for CO ₂ gas welding a carbon dioxide (CO ₂ ) in order to prevent welding defects due to wind around to ensure that the inlet is formed to be smaller to be discharged by pressing the tip of the nozzle body, the discharge pressure of the shielding gas for welding rising gas Invar relates to a nozzle, according to the present invention is to CO ₂ for welding gas nozzle consisting of a diffuser coupled to the nozzle body and the insulator integrated or screwed to the insulator, the nozzle body while being engaged with the diffuser an insulator coupled with the entrance guide portion integrally with ejected by pressing the front end of the nozzle body for guiding the shielding gas to form a pressure rise tube to ensure that the discharge pressure of the shielding gas is raised, and so as to prevent the welding defect due to wind around what has that feature.
