PURPOSE: A replaceable nozzle for a carbon dioxide welding torch is provided to replace only the front end of the nozzle which is deformed by a high temperature arc and which a welding slag adheres to. CONSTITUTION: A main tube has one end which is installed on a torch body (11); and wraps around a gas diffuser (13) which is installed on the front end of the torch body, and a contact tip which is installed on the front end of a gas diffuser. The guide tube is located in between the main tube and the gas diffuser; and guides a gas, which is discharged from an outlet formed on the outer circumferential surface of the gas diffuser, to the other end of the main tube. |
