The electrode connecting body is provided with a protection gas pipe communicating with the gas distributor.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to an argon arc welding torch with a cooling function and a welding device with the argon arc welding torch. Background technique [0002] Argon arc welding technology is based on ordinary arc welding, using argon gas to protect metal welding materials, and through high current to melt the welding materials on the base material to be welded into a liquid state to form a molten pool, so that the metal to be welded and the welding materials reach a A welding technique combining metallurgy, because argon gas is continuously supplied during high-temperature fusion welding, so that the welding material is not in contact with the oxygen in the air, thereby preventing the oxidation of the welding material, so it can weld stainless steel and iron metals. Argon arc welding equipment consists of welding machine, welding torch, control box, water and electricity, ground wire and grou...

AI Technical Summary

Problems solved by technology

[0004] The gas flow of the argon arc welding torch in the prior art is difficult to control, the heat dissipation point of the welding torch is far away from the heat point, the heat dissipation is poor, the tungsten electrode is severely ablated, the arc cannot be accurately controlled, and the operation is also troublesome; due to structural limitations, the energy density of the arc It cannot be further improved, making it difficult to improve the welding efficiency, the welding quality is affected, and the adaptability of welding materials is also affected

In addition, there is still a lack of technology in the prior art that can effectively cool the heating point of the gun body, which makes the temperature of the heating point of the gun body higher, which is not conducive to prolonging the service life of the insulating material and is not conducive to safe operation
