Alternating current-direct current arc welding machine

Abstract

The invention discloses an AC and DC arc welding machine. Its structure includes a regulating wheel, a transformer, an upper cover, a lifting ring, a body, a rapid radiator, a handle, a walking wheel and a base. The body consists of eight vertices, four The curved surface is formed into a rectangle, the left and right end surfaces of the body are parallel to each other, the upper and lower end surfaces of the body are symmetrical with each other, the front of the body and the adjusting wheel are movably connected by an interference fit, the adjusting wheel is connected with the handle, and the body The inner cavity is provided with a transformer, the upper end face of the body is gap-fitted with the upper cover, the upper cover is provided with a lifting ring, and there are two lifting rings in total. A rapid radiator is installed in the DC arc welding machine to dissipate the heat generated by the AC and DC arc welding machine when it is working, reduce the temperature of the inner cavity of the machine, prevent the AC and DC arc welding machine from burning out, and increase the service life of the AC and DC arc welding machine. .

Description

technical field [0001] The invention is an AC and DC arc welding machine, which belongs to the field of mechanical equipment. Background technique [0002] The AC and DC arc welding machine is composed of moving iron core transformer, rectifier, reactor, switch and other main components. By changing the size of the moving iron core gap, the current stepless adjustment is realized. It can be used for welding of high carbon steel, alloy steel, copper and cast iron with high technical requirements. [0003] The prior art discloses an AC / DC arc welding machine with the application number: 96247728.1, which can simultaneously have multiple functions such as voltage stabilization, voltage regulation, and DC output. The coil is wound on the annular iron core in layers, and the layers are separated by an insulating layer. The primary coil has several taps, which are used as a voltage-stabilized AC output, and the secondary coil also has several taps. After rectification, filterin...
