In the welding device, due to the arrangement of the welding mechanism with the impact piece 301, the conductive rod can be subjected to capacitive energy storage welding, and the welding quality of the conductive rod wire with smaller diameter is good; in addition, due to the addition of the lead wire mechanism, the axial direction of the first lead wire tube 201 in the lead wire mechanism and the axial direction of the needle tube 203 are not in the same straight line, so that the device is convenient to install, flexible adjustment and monitoring of the lead wire mechanism are facilitated, the structure of the whole device is more compact, excessive vertical space is not occupied, and meanwhile, the automation degree of the welding device can be improved.
In one embodiment, the lead mechanism may further have a motor 204 disposed on the device body 100 for driving the conductive rod to move in the first lead tube 201, the guide block 202 and the needle tube 203.
