Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only some sub-embodiments of the present invention. Based on the embodiments in the present invention, other embodiments obtained by the skilled in the art without creative work all belong to the protection scope of the present invention.

Referring to the attached drawings 1-3, an electric separation transmission welding and cutting gun comprises a welding head 1, a cable 2 and a gas pipe 3, wherein the welding head 1 comprises a three-way pipe 4, a pressing cap 5 connected with an upper opening 15 of the three-way pipe 4 and a connecting body 6 connected with a lower opening 16 of the three-way pipe 4, the three-way pipe 4 comprises a main pipe (not marked in the figure) and a branched branch pipe 17, the main pipe of the three-way pipe 4 is internally provided with a penetrating tungsten electrode 7, the cable 2 is parallel to the gas pipe 3, and the gas pipe 3 is separated from the cable 2, so that the protective gas is prevented from being influenced by the cable 2 to form spiral gas, and the welding and cutting effects of the welding and cutting gun are better; the cable 2 and the gas pipe 3 are sleeved with the corrugated pipe 8, and the corrugated pipe 8 has good insulation, is easy to bend, resists high temperature and high pressure, resists dirt and has attractive appearance. The two ends of the gas pipe 3 are connected with metal connectors 9, the two ends of the cable 2 are connected with metal sheets 10, for example, the metal sheets 10 can be copper noses, the metal sheets 10 are connected with the metal connectors 9, branch pipes 17 of the three-way pipe 4 are communicated with the metal connectors 9, and the metal connectors 9 are electrically communicated with the tungsten electrode 7 through the three-way pipe 4.
