Abstract

The invention relates to a portable rechargeable electric welding machine. The portable rechargeable electric welding machine solves the problems that no-load voltage between trigger weld handles of an existing generating electric welding machine threatens personal safety, the electric welding machine is not within a visibility range of a welder, and safety of an intermediate link is uncontrollable. Five groups of batteries are adopted to serve as a direct-current power source, are in series connection to form a 320V direct-current welding power supply mode, and are in parallel connection to form a non-welded mode. A sixth group of batteries are arranged in a casing and are connected with an alternating current output end through an inverter. A welding module comprises an inversion power output circuit, a transformer, an output rectifying circuit and a main control unit. The direct-current power source is connected with the inversion power output circuit, the inversion power output circuit is connected with the transformer, and the transformer is connected with the output rectifying circuit. Battery packs serve as the direct-current power source, an external power source is not used, the electric welding machine can be placed within a safety rang of an electric welding position, a weld line length is appropriate, pull of a weld line is avoided, danger is avoided, and the electric welding machine is always within the visibility range of the welder, is in a controllable state and is high in safety.

Description

technical field [0001] The invention relates to an electric welding machine, in particular to a portable rechargeable electric welding machine which is powered by a rechargeable DC battery and is easy to carry. Background technique [0002] In electric power construction, electric welding is required for making grounding grids, fixing electrical equipment, and making bridges, and electric welding is also required for emergency repair work involving equipment replacement and installation. Therefore, electric welding construction has become an essential part of electric power engineering. process. [0003] Current welding machines are generally powered by an AC grid, and the power supply is 380 / 200V. Due to the poor construction environment of new projects, the construction unit often needs to provide its own power supply, or the construction needs to provide its own power supply when the equipment fails and the power is cut off during emergency repairs. The welding operation...
