Problems solved by technology

[0023] However, since it is impossible to switch from a double nozzle structure to a single nozzle structure, or from a single nozzle structure to a double Nozzle structure, so it must be prepared separately, and the purchase cost is also increased, so it is very inconvenient
And, the above-mentioned MIG welding torch 200 also has the same inconvenience

Abstract

The present invention provides an adapter kit for converting a welding torch from a single nozzle structure to a double nozzle structure. The adapter kit (20A) of the present invention is configured to be attached to the welding torch (1A) having a single nozzle structure. The adapter kit (20A) comprises: an attachment (7A) configured to be installed on a torch body (5) after detaching a gasket in a state where a torch nozzle (inner nozzle) (6A) is inserted in the attachment (7A), the attachment (7A) having a flow passage for supplying a second shield gas; and an outer nozzle (8A) configured to be installed on the attachment (7A) around the torch nozzle (6A), the second shield gas being discharged through the outer nozzle (8A).

Description

technical field [0001] The invention relates to a welding torch and an adapter set thereof. [0002] This application claims priority based on Patent Application No. 2011-029724 for which it applied in Japan on February 15, 2011, and uses the content here. Background technique [0003] Welding of structures (objects to be welded) using metal or non-ferrous metal as the base material has conventionally used a non-consumable electrode called GTAW (Gas Tungsten Arc welding) such as TIG welding (Tungsten Inert Gas welding) or plasma arc welding. Consumable electrode type gas shielded welding called GMAW (Gas Metal Arc welding) such as MIG welding (Metal Inert Gas welding), MAG welding (Metal Active Gas welding) or carbon dioxide arc welding (Also known as semi-automatic arc welding). [0004] These welding methods generally use a welding torch with a single nozzle structure to generate an arc between the electrode and the object to be welded for welding. In addition, during w...
