Abstract

The invention relates to a welding gun for protecting carbon dioxide gas. The welding gun comprises a welding gun base and an elbow pipe body arranged at the front end of the welding gun base, wherein a handle is arranged on the welding gun base; a gas pipe joint is arranged at the tail end of the handle through a gas inlet nut in a sleeving way and is connected with a protective gas inlet; a cable is arranged outside the gas pipe joint; a front gun body is arranged in the welding gun base; a mounting hole is formed in the front gun body; the handle and the elbow pipe body are connected by internal threads and external threads on the elbow pipe body; a connecting rod is arranged at the front end of the elbow pipe body in a sleeving way and is connected with a current contact nozzle; a gas outlet is formed in the front end of the connecting rod; a spray pipe is arranged outside the current contact nozzle in a sleeving way; an insulator for insulating the gun body from the spray pipe is arranged between the connecting rod and the spray pipe. The spray pipe is arranged on the welding gun for protecting the carbon dioxide gas, disclosed by the invention, can be used for protecting gas from dispersing; in addition, the welding gun is good in insulating property and is not limited to an operating position, so that the welding efficiency is greatly improved; the welding gun has the advantages of concentrated electric arc temperature, small heat input, high speed and good protection effect.

Description

technical field [0001] The invention relates to the technical field of welding devices, in particular to a carbon dioxide gas shielded welding torch. Background technique [0002] At present, gas shielded welding is widely used in various steel structure projects due to its advantages of high welding efficiency, convenient operation, and high welding quality. Gas shielded welding relies on inert gas to protect the welding pool to obtain qualified welds. Therefore, the stability of the shielding gas flow must be ensured during the welding process. Due to the poor effect of ordinary welding guns, the gas is easy to disperse, and it will cause welding difficulties when used for special welding, which will affect the welding efficiency, the insulation effect is not ideal, and there are defects such as slow speed, non-concentrated temperature, and high equipment investment costs. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
