[0006] In addition, in order to improve the convenience of handling, the gas shielded welding machine in the related art is usually provided with traveling wheels at the bottom of the housing, but when the above gas shielded welder is in use, as the staff moves on the workpiece to be welded The movement of the welding seam often leads to the insufficient length of the composite cable connecting the welding torch to the welding machine. At this time, the staff needs to get up and push the welding machine to get close to the welding of the workpiece to be welded, which leads to the convenience of use. Therefore, there are certain improvements

Description
technical field [0001] This application relates to the field of electric welding machines, in particular to an all-digital multifunctional double-pulse gas shielded welding machine. Background technique [0002] Welding is an important leading manufacturing process technology in industrial manufacturing, petrochemical industry, west-east gas transmission, transportation equipment, construction engineering, and aerospace. The quality of its technical equipment directly affects the quality, reliability, life and production of products. effects and costs, etc. [0003] Gas shielded welding generally uses meltable welding wire as the electrode, and uses the arc burning between the continuously fed welding wire and the workpiece to be welded as the heat source to melt the welding wire and the base metal. During the welding process, the shielding gas is continuously delivered to the welding zone through the torch nozzle, so that the arc, the molten pool and the surrounding base m...
