Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide gas welding machines, in particular to a carbon dioxide gas shielded welding machine. Background Art

[0002] A carbon dioxide gas shielded welder (CO2 welder) is a common welding equipment that uses carbon dioxide gas as a shielding gas to protect the welding area from the effects of oxygen and moisture in the air. CO2 welders are commonly used for metal welding, especially steel welding. Its working principle is to spray carbon dioxide gas into the welding area to form a protective atmosphere, ensure that the welding area is not contaminated by oxygen, and reduce the generation of oxidation and hydrogen cracks. Carbon dioxide gas can also provide additional cooling effects, which helps to control the temperature during welding. CO2 welders usually use a DC power supply, ground the anode, feed the electrode through continuous wire feeding, and spray carbon dioxide gas to form a protective atmosphere. During the welding process, an arc is generated between the welding wire and the workpiece, and welding is achieved by melting the welding wire and the workpiece.

[0003] A carbon dioxide gas shielded welding machine will generate a lot of heat during operation. If the heat cannot be dissipated in time and effectively, the temperature of the welding machine will be too high, affecting its normal operation and life. At the same time, in order to facilitate the fixation of carbon dioxide gas cylinders of different specifications, a carbon dioxide gas shielded welding machine that can dissipate heat from the box and facilitate the fixation of carbon dioxide gas cylinders of different specifications is proposed to solve the above problems, which helps the welding machine to transfer the generated heat in time and maintain the normal operating temperature of the welding machine.
