Problems solved by technology
[0002] In projects such as pipelines and steel structures, there is a large amount of welding, especially in the environment of high-altitude operations. According to the requirements of the process and the actual welding situation, the welders have to adjust the welding current and turn off the welding from the high altitude to the ground. Power supply; especially in the process of operation, when it is necessary to change the welding process, or change the thickness of the weldment, the material, and the environment, it is necessary to adjust the welding current frequently, which brings a lot of inconvenience to the operation; even in order to save time And worrying about the safety of high altitudes, the welding current has not been adjusted in extreme cases, which has brought great hidden dangers to the welding quality, so that when the pressure test is carried out, welding joints often leak, and even cause pipelines, Collapse accident of steel structure
