[0002] The traditional melting electrode welding machine only adopts the DC welding mode, the welding wire is connected to the positive electrode of the welding torch, and the workpiece is connected to the negative electrode of the welding torch. The fuse speed is fast, but the heat of the melting wire and the melting base material cannot be controlled; A certain amount of heat is required to melt the welding wire. At this time, it is easy to cause the base metal to input too much heat, and the plate is easy to deform and perforate; when welding a thick plate, because the base metal needs a large input heat, the fuse time needs to be the same as that of the base material. The melting time of the material is matched, and the welding speed is reduced

technical field [0001] The invention relates to the field of welding machines, in particular to an AC / DC melting electrode welding machine. Background technique [0002] The traditional melting electrode welding machine only adopts the DC welding mode, the welding wire is connected to the positive electrode of the welding torch, and the workpiece is connected to the negative electrode of the welding torch. The fuse speed is fast, but the heat of the melting wire and the melting base material cannot be controlled; A certain amount of heat is required to melt the welding wire. At this time, it is easy to cause the base metal to input too much heat, and the plate is easy to deform and perforate; when welding a thick plate, because the base metal needs a large input heat, the fuse time needs to be the same as that of the base material. The melting time of the material is matched, and the welding speed is reduced. Contents of the invention [0003] In order to overcome the def...
