Welding gun for flux-cored wire

Abstract

The invention discloses a welding gun for a flux-cored wire, comprising a fire necking hole, a bend and a cable sleeve, wherein one end of the fire necking hole is communicated and fixedly connected with the other end of the bend; one end of the bend is fixedly connected with the cable sleeve; and the cable sleeve is internally provided with a welding wire tube and a cable set, wherein the cable set comprises a cable wire and a switch wire. By means of the welding gun, the weight of the welding gun is effectively lightened by removing an air tube in the cable set of the welding gun, and thus the usage loads of users and the manufacture and use cost of the welding gun are reduced; in addition, the repeated protection during welding is also avoided, and the usage of carbon dioxide is cancelled; and therefore the welding gun disclosed by the invention accords with the concept of modern low carbon and environmental protection.

Description

technical field [0001] The invention relates to a welding torch, in particular to a welding torch for flux-cored welding wire. Background technique [0002] At present, the commonly used welding method is carbon dioxide shielded welding. This welding method is to weld the welding wire under the protection of carbon dioxide gas. There is also a device to provide carbon dioxide gas on the machine. The welding machine is expensive, inconvenient to use, and emits a large amount of carbon dioxide, which is not good for the environment. Now, the new type of flux-cored welding wire does not need to use carbon dioxide as a shielding gas because of the protection of the flux core during welding. , There is no special welding torch for this kind of flux-cored wire on the market, and carbon dioxide shielded welding torch is still being used at present. The cable group of this welding torch is equipped with a gas pipe for supplying carbon dioxide, so that the welding is repeatedly prote...

[0002] At present, the commonly used welding method is carbon dioxide shielded welding. This welding method is to weld the welding wire under the protection of carbon dioxide gas. There is also a device to provide carbon dioxide gas on the machine. The welding machine is expensive, inconvenient to use, and emits a large amount of carbon dioxide, which is not good for the environment. Now, the new type of flux-cored welding wire does not need to use carbon dioxide as a shielding gas because of the protection of the flux core during welding. , there is no special welding torch for this kind of flux-cored wire on the market, and carbon dioxide shielded welding torch is still being used at present. Since the cable group of this welding torch is equipped with a gas pipe for supplying carbon dioxide, the welding is repeatedly protected during welding.
