Welding machine is a simple operation, the structure of science, for a wide range of high-quality welding, in the course of regular inspection and maintenance, can effectively extend its life. Before using welding machines, we should check the track is clean, no abnormal object; the power switch is normally safe; solder powder use is smooth; spools are whether the smooth functioning; and to ensure that the welder is in a safe environment. When the welding operation, we need to pay attention to have connected to the mains, the gantry driving power source and the welding power source, the telescopic column is raised, and then the height of the telescopic column is adjusted so that the handpiece is placed weldment opening edge; with weld shape Adjust the height, press the manual switch wire, welding wire sent, scissors cut the wire with iron carbide parts to an acute angle is appropriate, beneficial arcing. In addition, it should be noted that when the door frame is welded in a stable state, prohibiting movement or shaking of the circulatory state flux have a clear grasp ensure all generally prevent clogging phenomenon.
