The double-gun argon arc welding machine comprises a shell, wherein an operation panel is arranged at the slope position of the front surface of the shell, a direct current output port is formed in the lower end of the front surface of the shell, and a cover plate is rotatably mounted in the middle of the side surface of the shell through hinges; and four rollers are mounted at the edge of the lower surface of the shell in a rectangular distribution manner, lifting handles are symmetrically mounted at the two ends of the upper surface of the shell, an isolation device is embedded into the middle of the rear surface of the shell, and an air inlet connector is formed in the bottom end of the rear surface of the shell. According to the double-gun argon arc welding machine, a smoke absorption device is arranged in the shell of the arc welding machine, particles and partof pollution gas in smoke are adsorbed and purified through an activated carbon adsorption plate, ozone in the smoke is heated and decomposed into oxygen through heating plates, and a temperature sensor can conveniently detect the heating temperature in real time; and then the optimal temperature required by ozone decomposition is accurately controlled, and the decomposition efficiency is improved.

Description

Technical field[0001]The invention relates to the technical field of welding equipment, in particular to a double gun argon arc welding machine.Background technique[0002]Argon arc welding is a welding technique that uses argon as a shielding gas. It is also called argon shielded welding. It is to pass argon shielding gas around the arc welding to isolate the air from the welding area to prevent oxidation of the welding area. The argon arc welding technology is based on the principle of ordinary arc welding. It uses argon gas to protect the metal welding material. Through high current, the welding material is melted into a liquid on the welded substrate to form a molten pool, so that the welded metal and A welding technology in which the welding material achieves metallurgical bonding. Because the argon gas is continuously supplied during high-temperature melting welding, the welding material cannot be in contact with oxygen in the air, thereby preventing the oxidation of the welding...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been resolved: 1. When argon arc welding is carried out inside containers such as oil storage tanks, since argon arc welding will produce a large amount of ozone during the welding process, The ozone in the container is not easy to disperse, so the operator needs to wear a welding mask to operate, but the protective ability of the welding mask is limited, and it cannot completely isolate the air. After ozone is inhaled into the human body, it will cause damage to the human body. However, the internal space of the container is limited, so it is best to place it for ventilation and purification. The adsorption and purification of ozone by the equipment will hinder the operator from performing welding operations, so a new type of argon arc welding machine with ozone purification and adsorption function is needed; 2. Argon arc welding machines usually dissipate heat through water cooling and fan cooling, for To cooperate with fan heat dissipation, heat dissipation windows are required. During construction work in the desert, due to the large wind and sand, it is easier for dust to enter the interior of the argon arc welding machine through the heat dissipation window, which will affect the heat dissipation performance of the argon arc welding machine and seriously cause argon arc welding. The burning of the welding machine, causing property damage
